Iceland is a paradise for hot spring lovers! Imagine soaking in a steamy natural pool, surrounded by rugged volcanic landscapes, northern lights dancing above. From world-famous spas like the Blue Lagoon to remote, hidden gems, Iceland offers some of the world’s most breathtaking geothermal bathing experiences. In this guide, I’ll take you through the best hot springs and hot tubs in Iceland, from luxurious resorts to off-the-beaten-path natural pools. Whether you’re a first-time visitor or a seasoned traveler, these spots are must-visit for a truly Icelandic experience. Let’s dive in!
The Science Behind Iceland’s Geothermal Hot Springs
Ever wondered why Iceland is full of geothermal pools and natural hot springs? It all comes down to the island’s fiery origins. Iceland sits on the Mid-Atlantic Ridge, where the Eurasian and North American tectonic plates slowly pull apart. This creates a hotspot of volcanic activity, heating underground water and pushing it up to the surface. The result? Steamy, mineral-rich hot springs scattered across the country, from the famous Blue Lagoon to remote gems like Hrunalaug and Landmannalaugar hot pools.
The geothermal energy powering these springs isn’t just about warm water—it’s a complex process involving underground reservoirs, porous volcanic rock, and extreme pressure. As rainwater seeps into the ground, it travels deep beneath the surface, where it’s superheated by magma. When the pressure builds up enough, the hot water rises back up, forming bubbling geothermal pools and, in some cases, even dramatic geysers like Strokkur.
The Benefits of Geothermal Bathing
Taking a dip in one of Iceland’s hot water pools isn’t just relaxing—it comes with a host of health benefits. The high mineral content, especially silica, sulfur, and magnesium, is known to improve skin health and soothe conditions like eczema and psoriasis. This is why the Blue Lagoon’s silica mud masks have become a skincare sensation.
Beyond skincare, hot spring therapy helps muscle relaxation, improves circulation, and relieves stress. Many visitors to Iceland claim they feel completely rejuvenated after soaking in the natural hot tubs around the country. And it’s not just anecdotal—studies show that thermal pools can help reduce inflammation and even boost metabolism. No wonder Icelanders have been enjoying their sundlaugar (public geothermal swimming pools) for centuries!
Why Hot Spring Temperatures Vary
Not all Iceland geothermal pools are created equal—some are comfortably warm, while others are scalding hot! This depends on how deep the water has traveled underground and how much cold groundwater mixes in before reaching the surface.
- Blue Lagoon & Sky Lagoon: Maintained between 37-40°C (98-104°F) for optimal relaxation.
- Myvatn Nature Baths: Slightly hotter, usually between 38-41°C (100-106°F).
- Reykjadalur Thermal River: Cooler near the entrance, hotter the further upstream you go.
- Landmannalaugar hot pools: Can vary significantly depending on recent rainfall and geothermal activity.
- Hrunalaug Hot Spring: A cozy 38°C (100°F) but can fluctuate with weather changes.
Some natural hot pools in Iceland can reach dangerous temperatures, exceeding 80-100°C (176-212°F). That’s why it’s always important to check local conditions before taking a plunge. Many of the best hot springs in Iceland are well-regulated, but for remote spots, a quick water test with your hand or foot is a must!
Iceland’s geothermal wonders are more than just a tourist attraction—they’re a natural gift shaped by volcanic forces. Whether you’re soaking in the Secret Lagoon, hiking to the hot river in Reykjadalur, or exploring hidden hot tubs off the beaten path, you’re experiencing one of Earth’s most powerful geological processes firsthand.
Best Hot Springs in Iceland (Natural & Commercial)
Blue Lagoon – Iceland’s Most Famous Hot Spring
If there’s one hot spring in Iceland that everyone has heard of, it’s the Blue Lagoon. This geothermal spa isn’t just famous—it’s practically an Icelandic icon. The first time you see it, it almost looks unreal. The water has this striking milky-blue color, which comes from its unique mix of silica, algae, and minerals. Not only is it breathtaking, but it’s also incredibly soothing for the skin.
One of the biggest draws of the Blue Lagoon is its luxurious spa experience. Sure, you can just soak in the warm 38-40°C (100-104°F) waters, but why stop there? Most visitors swear by the silica mud masks, which you can slather on your face while floating under the Icelandic sky. There’s also an on-site sauna, steam cave, and waterfall massage area, making it more of a wellness retreat than just a hot spring. If you really want to take it up a notch, check out the Retreat Spa, where you’ll get access to exclusive private hot pools, in-water massages, and even a floating therapy experience.
Best Times to Visit & Ticket Pricing
The Blue Lagoon is open year-round, and each season offers a unique experience. Summer (June-August) means long, bright days where you can soak up the Midnight Sun, while winter (November-March) is perfect for watching the Northern Lights dance above the steamy waters. But no matter when you visit, one thing is certain—it’s always crowded.
To avoid the masses, book your tickets in advance and aim for an early morning or late evening slot. The first time slot of the day (usually around 7 AM or 8 AM) is the best if you want peace and quiet. Alternatively, a visit after 8 PM can offer a more serene experience.
As for pricing, the Blue Lagoon isn’t cheap, but it’s worth it. Ticket prices vary depending on the package you choose:
- Comfort Package (€64-80) – Includes entrance, a silica mud mask, towel, and one free drink.
- Premium Package (€86-100) – Adds a second mask, slippers, a bathrobe, and a glass of sparkling wine if dining at Lava Restaurant.
- Retreat Spa (€210-500) – Full access to the exclusive Retreat Lagoon, private changing rooms, and premium spa services.
Pro Tips:
- Book early – Tickets sell out fast, especially in peak season.
- Bring your own towel if you don’t want to pay extra for rentals.
- Rinse thoroughly before and after swimming—the high silica content can make your hair stiff if not washed properly.
- Try visiting in winter for a chance to soak under the Northern Lights—an experience you’ll never forget!
While some travelers find the Blue Lagoon too commercialized, there’s no denying that it’s a must-visit geothermal pool when in Iceland. Whether you’re here for the mineral-rich waters, spa treatments, or just the Instagram-worthy scenery, it’s an experience you won’t regret!
Sky Lagoon – A New Geothermal Luxury
If the Blue Lagoon is Iceland’s most famous geothermal spa, then Sky Lagoon is its sleek, modern rival. Opened in 2021, this geothermal hot pool has quickly become one of the best hot springs in Iceland, attracting visitors who crave a more exclusive and authentic Icelandic bathing experience. The highlight? Its stunning infinity-edge lagoon that blends seamlessly into the Atlantic Ocean, creating the illusion that you’re floating at the edge of the world. Whether you’re soaking at sunset or under the Northern Lights, the views here are nothing short of spectacular.
The Icelandic 7-Step Ritual: A Deep Relaxation Experience
Unlike other Iceland geothermal pools, Sky Lagoon isn’t just about soaking—it’s about wellness and tradition. The spa features a unique 7-Step Ritual, inspired by classic Icelandic bathing culture. Each step is designed to boost circulation, detoxify the body, and deeply relax the mind.
Here’s what the experience looks like:
- Warm Up in the Infinity Lagoon – Let the geothermal water melt away tension as you take in the panoramic ocean views.
- Cold Plunge – A quick dip in an icy plunge pool helps awaken your senses and improve circulation.
- Sauna with a View – Step into a stunning glass-walled sauna with an ocean view, where the dry heat helps cleanse toxins.
- Cold Fog Mist – A refreshing mist cools the body, preparing you for the next step.
- Salt Scrub Exfoliation – A rejuvenating body scrub leaves your skin soft and glowing.
- Steam Room Relaxation – The warm steam helps open pores and enhances the effects of the scrub.
- Final Rinse in a Warm Shower – The final step washes away impurities, leaving you completely refreshed.
This ritual is what sets Sky Lagoon apart from other Icelandic hot springs, offering a full sensory spa experience rather than just a soak in hot water pools.
Why Sky Lagoon is Becoming a Top Competitor to the Blue Lagoon
With its sleek, modern design and authentic Icelandic spa experience, Sky Lagoon is quickly challenging the Blue Lagoon’s dominance. While both are geothermal spas, they offer very different atmospheres.
| Feature | Blue Lagoon | Sky Lagoon |
|---|---|---|
| Scenery | Volcanic lava fields | Oceanfront infinity view |
| Crowds | Very busy, high tourist volume | More exclusive, limited capacity |
| Mineral Water | Silica-rich, milky-blue water | Saltwater blend, natural ocean feel |
| Experience | Spa & soaking | 7-step wellness ritual |
| Best for | First-time visitors, Instagram shots | Luxury spa-goers, deep relaxation |
Sky Lagoon is less crowded than the Blue Lagoon and offers a more serene, exclusive feel. Many visitors even prefer it over the Myvatn Nature Baths and Secret Lagoon, praising its intimate ambiance and luxury spa treatments.
If you’re looking for a modern yet authentic hot spring experience in Iceland, Sky Lagoon should be at the top of your list. Whether you’re indulging in the 7-Step Ritual, enjoying the breathtaking infinity pool, or simply soaking under the midnight sun, this geothermal spa is redefining luxury hot tubs in Iceland.
Secret Lagoon – The Oldest Hot Spring in Iceland
If you’re looking for a geothermal hot spring in Iceland that offers an authentic, rustic charm, the Secret Lagoon (Gamla Laugin) should be on your list. Unlike the ultra-modern Blue Lagoon and Sky Lagoon, this natural hot pool keeps things simple and traditional. Nestled in Flúðir, right in the heart of Iceland’s famous Golden Circle, it’s the oldest swimming pool in Iceland, dating back to 1891. What makes it special? Steaming geothermal vents, bubbling hot pots, and an untouched natural setting that transports you back to Iceland’s early bathing culture.
A True Natural Experience with Steaming Geothermal Surroundings
The Secret Lagoon isn’t a man-made spa—it’s a naturally heated geothermal pool, surrounded by moss-covered lava rocks and active hot springs. As you soak in the warm 38-40°C (100-104°F) waters, you’ll see small geysers bubbling and steaming just a few feet away, adding to the otherworldly atmosphere. The water here is rich in minerals, making it great for skin health and muscle relaxation after a long day of exploring.
One of the most unique features is Litli Geysir, a tiny geyser that erupts every few minutes, releasing bursts of steam into the air. Unlike crowded tourist-heavy hot springs, Secret Lagoon offers a more peaceful, laid-back experience where you can fully connect with Iceland’s geothermal wonders.
Perfect Stop Along the Golden Circle
One of the best things about Secret Lagoon is its location. It’s just a short detour from the Golden Circle, making it a perfect stop after visiting Þingvellir National Park, Gullfoss Waterfall, and Geysir Hot Springs. Instead of fighting the crowds at major tourist attractions, you can unwind in one of Iceland’s hidden hot springs and soak under the northern lights in winter or the midnight sun in summer.
A Hot Spring with Historical Charm
Beyond its natural beauty, Secret Lagoon carries a rich historical significance. It was Iceland’s first public swimming pool, used by locals for generations before modern spas took over. The pool was abandoned for years but was restored in 2014, preserving its original charm while improving facilities like showers and a small café. Unlike flashy resorts, this place remains simple, authentic, and deeply connected to Iceland’s bathing traditions.
Why Choose Secret Lagoon?
If you want a hot spring experience that’s less touristy than the Blue Lagoon, cheaper than Sky Lagoon, and more natural than Myvatn Nature Baths, Secret Lagoon is an excellent choice. It’s a blend of history, nature, and relaxation, all in one scenic location.
💦 What to Know Before Visiting:
- Entrance Fee: Around 3000 ISK (€20-25) per person
- Opening Hours: Open year-round, best visited in the morning or late evening for a quieter experience
- What to Bring: Swimsuit, towel, and waterproof sandals (or rent them on-site)
- Best Time to Visit: Winter for Northern Lights viewing, summer for a secluded soak under the Midnight Sun
For those who prefer a traditional, no-frills geothermal soak, Secret Lagoon remains one of Iceland’s best-kept secrets. It may not be as flashy as the Sky Lagoon or as famous as the Blue Lagoon, but it offers something even more special—a chance to experience Iceland’s hot spring culture just as locals did over a century ago.
Myvatn Nature Baths – The Blue Lagoon of the North
If you’re heading to North Iceland and want a geothermal spa experience without the crowds and high prices of the Blue Lagoon, Myvatn Nature Baths is the perfect alternative. Often called the “Blue Lagoon of the North,” this hidden gem offers milky-blue, mineral-rich waters set against a stunning volcanic landscape. Located near Lake Mývatn, this hot spring provides a more intimate and natural setting, making it one of the best geothermal pools in Iceland for those seeking relaxation with fewer tourists.
A Less Crowded, More Authentic Hot Spring Experience
Unlike the Blue Lagoon, which can feel like a high-end spa resort, Myvatn Nature Baths has a more laid-back and local vibe. While the mineral content of the water is similar—rich in silica, sulfur, and geothermal minerals—the experience here feels more natural and peaceful. The pools are carved into a lava field, creating a unique geothermal oasis that feels like it’s straight out of Iceland’s Viking past.
One of the biggest advantages of Myvatn Nature Baths is that it’s less crowded. Since it’s located in North Iceland, far from Reykjavik’s busy tourist spots, it tends to attract fewer visitors, even during peak season. This makes it an ideal hot spring for those looking for serenity and space to truly unwind.
Unbeatable Views Over a Volcanic Lake
What makes Myvatn Nature Baths stand out is its breathtaking location. As you soak in the warm 36-40°C (97-104°F) waters, you’ll be treated to panoramic views of Lake Mývatn, one of Iceland’s most stunning natural wonders. The area is surrounded by volcanic craters, lava formations, and steaming geothermal vents, making it one of the most scenic hot pools in Iceland.
If you visit during winter, you might even get lucky and see the Northern Lights while floating in the warm water—something you won’t experience at more crowded spots like the Secret Lagoon or Sky Lagoon.
Cheaper Than the Blue Lagoon but Just as Beautiful
Another major plus? Myvatn Nature Baths is much more affordable than the Blue Lagoon. While a standard Blue Lagoon ticket costs anywhere from €64-100, entrance to Myvatn Nature Baths is around 5000 ISK (€35-40), making it one of the best budget-friendly hot springs in Iceland.
💦 What to Know Before Visiting:
- Entrance Fee: Around 5000 ISK (€35-40) per person
- Opening Hours: Open daily, including late-night hours for Northern Lights viewing in winter
- Facilities: Showers, changing rooms, steam baths, and a café with local Icelandic snacks
- Best Time to Visit: Sunset or night-time for the most spectacular views
Is Myvatn Nature Baths Worth Visiting?
If you’re traveling in North Iceland, Myvatn Nature Baths is absolutely worth a visit. It offers the soothing, mineral-rich waters of the Blue Lagoon but with fewer people, lower prices, and a more rugged, natural setting. Whether you’re exploring the Diamond Circle, hiking near Hverfjall Crater, or just looking for a quiet hot spring experience, this is one of the best geothermal pools in Iceland to soak in.
Best Natural Hot Tubs and Hidden Gems
Seljavallalaug – Iceland’s Oldest Swimming Pool
Hidden in a breathtaking mountain valley on Iceland’s South Coast, Seljavallalaug is one of the country’s best natural hot tubs and a true hidden gem. Built in 1923, it’s the oldest man-made swimming pool in Iceland, yet it remains incredibly untouched and rustic. Surrounded by steep, moss-covered mountains, this remote geothermal pool offers a unique off-the-beaten-path experience, far removed from the commercialized Blue Lagoon or Sky Lagoon.
A Remote, Mountainside Pool with Stunning Scenery
What makes Seljavallalaug so special is its dramatic setting. Nestled in a secluded valley near the famous Eyjafjallajökull volcano, the pool is fed by natural geothermal water that keeps it warm year-round. However, unlike hot springs like Myvatn Nature Baths, Seljavallalaug is not artificially regulated, so its temperature fluctuates with the seasons. Expect the water to be lukewarm rather than piping hot—perfect for a long, relaxing soak while soaking in the majestic Icelandic landscape.
The pool is completely free to visit, and since it’s not part of a spa or tourist attraction, there are no crowds, no reservations, and no entrance fees—just pure Icelandic nature. If you’re looking for authentic geothermal bathing, this is one of the best hot springs in Iceland to experience.
Getting There: A Short Hike to Serenity
One reason Seljavallalaug remains a hidden gem is that you can’t just drive up to it—you’ll need to hike about 15-20 minutes from the parking area. The trail is relatively easy, following a gravel path alongside a small river, but it can get muddy or icy depending on the season.
💡 Pro Tips for Visiting:
✔ Wear waterproof hiking boots – The trail can be wet and rocky, especially after rain.
✔ Bring warm clothes – Iceland’s weather changes fast, and there are no heated facilities nearby.
✔ No changing rooms – There’s a tiny, run-down hut near the pool, but it’s not well-maintained. It’s best to wear your swimsuit under your clothes for a quick change.
✔ Pack snacks & water – There are no shops or cafes nearby, so bring what you need.
Is Seljavallalaug Worth Visiting?
If you’re an adventurous traveler looking for one of Iceland’s most unique hot pools, Seljavallalaug is absolutely worth it. While it doesn’t offer the steaming geothermal luxury of Secret Lagoon or the oceanfront views of Sky Lagoon, it provides something even rarer: a true wilderness experience. Imagine floating in a warm mountain pool, with nothing but rugged cliffs and Icelandic silence around you—it’s the kind of place that makes you feel like you’ve stepped back in time.
For those seeking a natural, secluded hot tub experience, Seljavallalaug remains one of Iceland’s best-kept secrets.
Landmannalaugar Hot Springs – A Hiker’s Paradise
Deep in Iceland’s Highlands, surrounded by the vibrant rhyolite mountains of Landmannalaugar, lies one of the most stunning natural hot springs in Iceland. Unlike commercialized geothermal spas like the Blue Lagoon or Sky Lagoon, these hot pools offer an entirely raw and untouched experience. After trekking through some of the most dramatic landscapes in Iceland, there’s nothing better than soaking in the steamy geothermal waters of Landmannalaugar, surrounded by lava fields, rolling hills, and bubbling vents.
A Geothermal Oasis in the Rhyolite Mountains
Landmannalaugar is famous for its otherworldly scenery, where shades of orange, pink, green, and yellow blend together across the mountains. These colors come from the volcanic rhyolite rock, a rare geological feature found in only a few places on Earth. At the heart of this rugged wilderness, the Landmannalaugar hot springs offer a perfect natural retreat for weary hikers and adventure seekers.
The geothermal pools here are naturally heated by volcanic activity, and the water temperature varies between 36-40°C (97-104°F), making it perfect for a long, relaxing soak. The hot springs are completely free, and there’s no spa infrastructure—just pure, Icelandic nature at its finest.
A Must-Visit for Hikers on the Laugavegur Trail
Landmannalaugar is the starting (or ending) point of the Laugavegur Trail, Iceland’s most famous multi-day trek. This 55 km (34-mile) hiking route takes trekkers through volcanic deserts, steaming geothermal valleys, black sand plains, and glacial rivers, offering some of the most breathtaking landscapes in Iceland.
Many hikers start or finish their trek with a dip in the Landmannalaugar hot springs, using the mineral-rich waters to soothe tired muscles after days of trekking. Even if you’re just visiting for a day hike, taking a soak in these natural hot tubs is an absolute must-do.
Best Time to Visit & Accessibility Tips
Since Landmannalaugar is located in the Icelandic Highlands, it’s only accessible during summer (June to early September). The F-roads (mountain roads) leading to the area are closed in winter due to harsh weather conditions, making it impossible to reach without a super jeep or guided tour.
🚗 How to Get There:
- By 4×4 Vehicle: The F208 road leading to Landmannalaugar requires a high-clearance 4×4, as it involves river crossings and rough terrain. Small rental cars are NOT allowed.
- By Bus: The Reykjavik Excursions Highland Bus operates in summer, offering daily trips from Reykjavik.
- By Tour: Several companies offer super jeep or guided hiking tours to Landmannalaugar from Reykjavik.
💡 Pro Tips for Visiting:
✔ Bring a swimsuit & towel – There are no rental options at the site.
✔ Prepare for unpredictable weather – Even in summer, temperatures can drop suddenly in the Highlands.
✔ Pack extra food & water – There’s a small mountain hut nearby, but no restaurants or shops.
✔ Be cautious of algae-covered rocks – The bottom of the hot spring can be slippery.
Why Visit Landmannalaugar Hot Springs?
If you’re looking for one of Iceland’s most remote and beautiful geothermal pools, Landmannalaugar hot springs are a must-visit. Whether you’re an experienced hiker tackling the Laugavegur Trail or simply an adventurer seeking off-the-beaten-path hot springs, this geothermal paradise offers a raw, natural experience unlike any other. Soak in the steamy waters, take in the colorful mountain views, and embrace the untamed beauty of Iceland’s Highlands!
Reykjadalur Hot River – A Natural Thermal Stream
For those seeking a truly untouched geothermal experience, Reykjadalur Hot River is one of the most incredible natural hot springs in Iceland. Unlike traditional hot tubs or geothermal pools, this is a naturally heated river nestled in a steaming valley just outside of Reykjavik. The name Reykjadalur literally translates to “Steam Valley”, and as soon as you arrive, you’ll understand why—geothermal vents, bubbling mud pots, and rising mist make the landscape look like something out of a fantasy novel.
What makes Reykjadalur unique is that the entire river is warm, meaning you can find your own little hot tub-like spot to relax in. The further upstream you go, the hotter the water gets, while downstream, it cools down as it mixes with cold mountain runoff. This gives you complete control over finding the perfect temperature for your soak!
A Scenic Hike Leads to This Geothermal Wonder
Unlike commercial hot springs like the Blue Lagoon or Sky Lagoon, Reykjadalur Hot River requires a bit of effort to reach—but that’s part of what makes it so special. You’ll need to hike about 3 km (1.8 miles) from the parking lot, but the journey is breathtaking.
The moderate hike takes about 45-60 minutes one way, with stunning views of rolling green hills, waterfalls, and steaming geothermal vents along the way. While the trail is not too difficult, there are some steep sections, so good hiking shoes are recommended.
🚶 Hiking Overview:
- Distance: ~6 km (round trip)
- Time: ~1.5-2 hours (plus soaking time)
- Difficulty: Moderate (some steep sections)
- Trail Condition: Gravel path, well-marked but can be slippery in wet weather
Completely Free – Just Nature at Its Finest
One of the best things about Reykjadalur Hot River is that it’s completely free. There are no entrance fees, no spa facilities, and no crowds of tourists with pre-booked time slots. This is Iceland at its most natural, offering a geothermal bathing experience that feels wild and untouched.
Unlike hot tubs in Reykjavik or geothermal spas, Reykjadalur has no artificial structures, just a few wooden platforms and walkways to help visitors access the river more easily. The rest is all pure Icelandic nature—steaming hills, warm currents, and endless tranquility.
Best Times to Visit & What to Bring
While Reykjadalur is open year-round, the best time to visit is during the summer and early fall (June-September) when the hiking trail is dry and easy to navigate.
Winter visits are possible, but the trail can be icy, muddy, and treacherous, so crampons and proper winter gear are a must. The payoff? Soaking in a steamy river while surrounded by snow-covered mountains!
💡 What to Bring:
✔ Swimsuit & Towel – There are no changing rooms, so you’ll need to change behind a rock or come prepared in your swimsuit.
✔ Good Hiking Boots – The trail can be slippery, especially after rain.
✔ Water & Snacks – No shops or cafés nearby, so pack your own.
✔ Warm Clothes for After – Iceland’s weather can be unpredictable, and you’ll want dry layers after your soak.
✔ Waterproof Bag – Protect your valuables while you’re in the water.
Why Reykjadalur is a Must-Visit Hot Spring
If you love adventure, hiking, and hot springs, Reykjadalur Hot River is one of the best natural hot tubs in Iceland. The combination of a scenic hike, completely natural thermal waters, and a crowd-free atmosphere makes this a must-visit geothermal experience.
Unlike the Secret Lagoon or Myvatn Nature Baths, which offer structured soaking areas, Reykjadalur is wild, free, and entirely up to nature’s design. Whether you visit under the Midnight Sun in summer or surrounded by snow in winter, soaking in this geothermal river will be one of the most unforgettable experiences of your trip to Iceland!
Hrunalaug – A Cozy Private Hot Spring
If you’re looking for a secluded, picturesque hot spring in Iceland, Hrunalaug is a hidden gem that feels like something straight out of a fairytale. Unlike the large, commercial geothermal spas like the Blue Lagoon or Sky Lagoon, this tiny, natural hot tub offers a truly intimate and peaceful experience. Tucked away in the countryside near Flúðir, not far from the Secret Lagoon, this small geothermal pool is perfect for those who want to escape the crowds and soak in pure Icelandic nature.
Small but Incredibly Picturesque
What makes Hrunalaug so special is its charming, untouched beauty. The pool is nestled in a grassy valley, surrounded by rolling green hills and a natural stream. The crystal-clear geothermal water flows from a nearby hot spring, keeping the pool at a perfectly warm 38-40°C (100-104°F). There are no artificial structures, just rocky edges and a rustic wooden shelter that adds to its cozy, old-world charm.
It’s one of the smallest hot springs in Iceland, with enough room for about 5-8 people at a time, making it an incredibly private and tranquil spot. If you’re lucky enough to visit when it’s empty, you’ll have one of the most peaceful hot tub experiences in Iceland all to yourself.
A Peaceful Dip Away from the Crowds
One of the biggest perks of Hrunalaug is that it remains relatively quiet compared to the more famous geothermal pools. While places like the Myvatn Nature Baths and Secret Lagoon attract tour buses and large groups, Hrunalaug is much more off-the-beaten-path.
It’s perfect for those who prefer a silent, meditative soak in nature rather than a bustling tourist attraction. The surrounding scenery is breathtaking, and if you visit during sunset or late at night, you might even catch the Northern Lights dancing above while you relax in the warm waters.
Private Land – A Small Donation is Required
Unlike public geothermal pools, Hrunalaug sits on privately owned land, and the owners have done a great job preserving its natural beauty. To help with maintenance and conservation, visitors are asked to pay a small donation (around 1000 ISK / €7 per person).
This fee helps keep the area clean and open to visitors, as some hot springs in Iceland have unfortunately been closed due to overcrowding and damage from tourism.
💡 Important Tips for Visiting:
✔ Respect the Land – Pack out all trash and leave no trace.
✔ No Changing Facilities – Be prepared to change in your car or behind a rock.
✔ Limited Space – Arrive early in the morning or late at night for the best chance of having it to yourself.
✔ Bring Cash for the Donation – While digital payments are sometimes accepted, cash is easier.
✔ Keep It Quiet – This isn’t a party spot—come to relax and enjoy nature in peace.
Is Hrunalaug Worth Visiting?
Absolutely. Hrunalaug is one of Iceland’s best natural hot tubs, offering a quiet, picturesque, and intimate geothermal experience that’s hard to find elsewhere. If you’re visiting the Golden Circle or Secret Lagoon, it’s well worth a short detour to experience this cozy, private hot spring. Whether you’re looking for a romantic soak, a solo escape, or a peaceful moment surrounded by nature, Hrunalaug is one of Iceland’s most magical geothermal treasures.
Hot Tubs and Geothermal Pools in Iceland’s Towns & Hotels
Iceland isn’t just about remote hot springs—it also has a rich bathing culture centered around sundlaugar, or public geothermal pools. While many visitors focus on big-name hot springs like the Blue Lagoon or Secret Lagoon, locals tend to prefer their neighborhood geothermal pools, which offer a more authentic and budget-friendly experience. Additionally, many hotels and lodges across the country feature private hot tubs that let you soak under the northern lights in total peace. Whether you’re looking for a local swimming spot in Reykjavik or a luxury geothermal spa, Iceland has plenty of hot water experiences to choose from.
Iceland’s Unique Sundlaugar (Public Pool) Culture
In Iceland, geothermal swimming pools are a way of life. Thanks to the country’s abundant geothermal energy, nearly every town has at least one public sundlaug (swimming pool) with naturally heated water. Unlike typical swimming pools, these hot tubs and pools are warm year-round, making them a social hub for Icelanders. Whether it’s summer or the middle of winter, locals gather at these pools to relax, chat, and even discuss politics.
💦 What to Expect at a Sundlaug:
- Multiple hot tubs at different temperatures (usually 38-42°C / 100-108°F)
- Lap pools with naturally heated geothermal water
- Saunas and steam rooms
- Cold plunge pools for contrast therapy
- Affordable entrance fees (usually 1000-1500 ISK / €7-10 per visit)

Leave No Trace: Protecting Iceland’s Fragile Ecosystem
Iceland’s geothermal pools and hot springs are a gift of nature, but many are delicate environments that can be easily damaged by careless tourism. Following Leave No Trace principles is crucial for preserving these spots:
✔ Pack Out What You Pack In – Take all trash, plastic bottles, and personal items with you. Many natural hot springs in Iceland don’t have trash bins, so be responsible.
✔ Avoid Using Soaps or Shampoos – Even biodegradable products can disrupt the natural mineral balance of hot springs. Rinse off before entering a geothermal pool.
✔ Stick to Marked Trails – Many hot springs, especially in the Highlands, are surrounded by sensitive moss and lava formations that take decades to recover from damage. Stay on designated paths to avoid harming the landscape.
✔ Respect Wildlife & Nature – Iceland’s geothermal pools are often home to small ecosystems. Avoid disturbing the hot water pools or leaving food scraps that could impact the local environment.
Respecting Local Customs and Bathing Etiquette
Hot springs and public geothermal pools (sundlaugar) are an essential part of Icelandic culture, and locals take their bathing traditions seriously. Understanding and respecting these customs will help you blend in and avoid awkward moments.
✔ Always Shower Naked Before Entering a Hot Spring or Pool – This is non-negotiable in Iceland. Public pools like Laugardalslaug or Myvatn Nature Baths require visitors to thoroughly wash without swimsuits before entering the water to keep the pools clean.
✔ Keep Noise Levels Low – While some hot springs are social spots, many visitors seek peace and relaxation. Avoid playing loud music or having disruptive conversations.
✔ Limit Time in Small Natural Hot Springs – If you’re at a hidden hot tub like Hrunalaug, be mindful of others waiting to enjoy it. These small pools can only accommodate a few people at a time.
✔ Ask Before Taking Photos – Many visitors come for a peaceful soak, not a photoshoot. If you’re in a public geothermal pool, be respectful and avoid taking pictures of strangers.
What to Bring: Towel, Swimsuit, and Flip-Flops
Being prepared can make your hot spring experience more comfortable and enjoyable. Iceland’s geothermal pools range from luxury spa facilities to wild, remote hot rivers, so pack accordingly.
✔ Swimsuit – Required at all public geothermal pools and hot tubs in Reykjavik. Some remote hot springs like Seljavallalaug and Reykjadalur have no changing rooms, so consider wearing it under your clothes.
✔ Towel – Some hot springs, like Blue Lagoon, offer rentals, but most natural pools require you to bring your own. Microfiber towels are great for hiking trips.
✔ Flip-Flops or Water Shoes – Many natural hot springs in Iceland have rocky or slippery bottoms. Flip-flops or water shoes are helpful, especially at places like Reykjadalur or Landmannalaugar.
✔ Dry Bag for Valuables – If you’re visiting hot rivers or remote pools, a waterproof bag helps keep your phone, wallet, and camera safe.
✔ Warm Clothes for After Your Soak – Iceland’s weather changes rapidly, and getting out of a hot spring into cold wind can be a shock. Bring layers, a hat, and gloves, especially in winter.
Best Times to Visit to Avoid Crowds
Iceland’s geothermal pools have become incredibly popular, and some places—especially the Blue Lagoon and Secret Lagoon—can get crowded. Here’s when to visit for a quieter, more peaceful soak:
✔ Early Morning (Before 9 AM) – The best time to visit popular hot springs like Sky Lagoon or Myvatn Nature Baths is as soon as they open. Morning visitors often get the pools to themselves.
✔ Late Night (After 8 PM) – Many geothermal spas in Iceland stay open late, offering a quieter atmosphere. Plus, in winter, this is the best time to soak under the Northern Lights.
✔ Off-Peak Seasons (Fall & Spring) – September-October and April-May are less crowded, with cooler air making the hot water pools even more enjoyable.
✔ Weekdays Over Weekends – Local geothermal pools like Laugardalslaug or Hofsós Swimming Pool are busiest on weekends when Icelanders take their weekly soak. Visit on a weekday for fewer people.
✔ Remote Hot Springs Require Planning – Places like Landmannalaugar and Hrunalaug have limited space. Try to visit off-hours or during shoulder seasons to avoid crowds.
Enjoy Iceland’s Hot Springs the Right Way
Iceland’s hot springs, geothermal pools, and natural hot tubs are among the country’s greatest treasures, but they can only stay that way if visitors respect nature, local customs, and fellow travelers.
