Unwind in Reykjavík’s Hot Springs and Pools

Reykjavík hot springs are not hidden deep in forests or tucked into distant lava fields. Here, they’re folded into everyday life. Steam rises behind schools. Hot tubs sit beside playgrounds. Locals stop by after work, towel in hand, to catch up on the day’s news. It’s Icelanders' version of the village square, just a little warmer.

If you’re visiting Iceland’s capital, a geothermal soak is the quickest way to feel like a local. Some spots are humble neighbourhood pools; others are sleek, modern spas. But at every pool, the water comes straight from the volcanic earth. It’s simple, it’s warm, and it’s how the city breathes.

Before you grab your towel, there are a few local secrets to keep in mind.

What to Know About Reykjavík Hot Springs and Geothermal Pools

First, a small but important distinction. You won’t find wild hot springs bubbling up between cafés and colourful houses in downtown Reykjavík. What you’ll find are geothermal pools, fed by naturally heated water drawn from deep beneath the city.

Iceland runs on this heat. It warms homes, clears winter pavements, and fills neighbourhood pools. The same energy that shapes lava fields also keeps the hot tubs at a steady 40°C (104°F). All while snow gathers quietly on the edges.

Curious how it all works? Step inside Elliðaárstöð. This historic power station in the Elliðárdalur Valley tells the story of Reykjavík’s journey to renewable heat. For a deeper look, head out to The Geothermal Exhibition at the Hellisheiði Power Plant. It’s a futuristic space where you can see massive turbines turning earth-steam into the city’s lifeblood.

Of course, you can’t miss Perlan in the city skyline. Those six silver tanks it sits on? They’re actually storage for the city’s hot water. Inside, the "Forces of Nature" exhibit lets you hear and feel the power of volcanoes and geothermal energy. It’s a great way to understand the heat before you jump in.

Now, back to the pools! Most geothermal pools in Reykjavík offer:

• Large swimming pools for laps
• A variety of hot tubs (usually 38–42°C/100–107°F)
• Steam rooms and saunas
• Chilling cold plunge pools
• Slides and play areas for the kids

The water here is mineral-rich and clear. It lacks that heavy sulfur "egg" scent you might find in the countryside. Most facilities have also received the city’s Rainbow Certification, ensuring an inclusive, LGBT+ friendly environment. Plus, many places have private changing rooms and wheelchair-accessible lifts.

Public Swimming Pools Within the Reykjavík Capital Area

While travellers often flock to expensive lagoons, locals head to the sundlaugar. There are 18 scattered swimming pools in Reykjavík, each with its own personality and its own regulars.

Here are a few you’ll hear about again and again:

• Laugardalslaug: The city’s largest pool. It features an Olympic-sized pool, a giant slide for the kids, and a saltwater tub pumped directly from the Atlantic. If it’s your first Reykjavík soak, this is a generous introduction.
• Vesturbæjarlaug: Tucked away in the West End near the university, this is perhaps the most "authentic" corner of the city. It’s cosy, slightly weathered in the best way, and perfect for people-watching. You’ll sit shoulder-to-shoulder with professors, poets, and families.
• Sundhöllin (Sundhöll Reykjavíkur): Step back into 1937. Located just a stone’s throw from the towering Hallgrímskirkja, this white Art Deco gem is the city’s oldest pool. While the indoor hall is a masterpiece of symmetry, the rooftop deck is the real prize. Soak in the hot tubs while watching the sun dip behind the Hallgrímskirkja church tower.
• Salalaug: If your muscles are weary from trekking through lava fields, head to Kópavogur. Salalaug features the Iðulaug pool, designed with targeted water jets for your calves and back. Even the benches in the hot tubs have built-in air massages. It’s a high-tech hug for your body.
• Seltjarnarneslaug: Perched on the edge of the Seltjarnarnes Peninsula, this is the only pool in the area filled with mineral-rich seawater. The locals swear by its healing properties for the skin. It feels a bit like bathing in a warm, filtered version of the ocean (without the sting of the wind).
• Álftaneslaug: Worth the short drive for the kids. It features Iceland’s only wave pool and indoor slides with neon light shows inside.

For visitors seeking authentic Reykjavík hot springs experiences, these public pools are often the best place to start.

Nauthólsvík: A Golden-Sand Beach With a Geothermal Pool

Can you swim in the North Atlantic? At Nauthólsvík Beach, the answer is a shivering yes. This man-made lagoon is a local miracle, where golden sand meets a sea warmed by geothermal runoff. In the height of summer, the lagoon reaches a balmy 18–22°C (64–71°F). But the nearby hot tubs stay much toastier for those who prefer a gentler soak.

Just beyond the sheltered water waits the open sea. Some swimmers move between the stinging cold of the Atlantic and the embrace of the heated pools back and forth. Would you dare?

Sky Lagoon: A Luxurious Geothermal Spa Experience

Craving a bit of luxury? The Sky Lagoon at the edge of the Kársnes Peninsula is the city’s modern sanctuary. Here, a 70-meter infinity edge spills directly toward the North Atlantic.

The heart of the experience is the 7-Step Skjól Ritual. It’s a rhythmic journey: you begin in the warm embrace of the lagoon before bracing for the cold plunge. From there, you move to a glass-walled sauna with views that stretch to the horizon. Followed by a refreshing cold mist and a signature sea salt scrub. The spa experience finishes with a heavy steam and a shot of tart crowberry elixir.

Top tip: Visiting on 12 August 2026? Sky Lagoon will host a viewing party for the total solar eclipse in Iceland. Be sure to book your slot well in advance!

Hvammsvík: Natural Hot Springs on the Edge of the Atlantic

Searching for more traditional hot springs near Reykjavík? A short drive from the city brings you to Hvammsvík Hot Springs. Located in the scenic Hvalfjörður (Whale Fjord), these eight natural hot springs are built right into the shoreline.

What makes Hvammsvík different is the tide. As the Atlantic rises, the lower pools shift with it. Cool salt water slips in and mingles with the geothermal heat. You can soak in the heat and watch eider ducks float by. If you’re lucky, you might even spot a seal bobbing in the fjord.

When you’re finished soaking, you can go hiking, try paddleboarding, or explore the barn community centre to play table games.

Tips and Reminders When Visiting Geothermal Pools in Reykjavík

To experience Reykjavík like a local and make the most of your time, keep these few things in mind:

• Follow the shower rule: You must shower naked with soap before putting on your swimsuit. This is strictly enforced at every public pool to keep the chemical-free water clean and hygienic.
• Bring swimming essentials: Bring your own towel and swimwear. Avoiding the rental desk can save you around 2,100 ISK per person (plenty for a round of treats afterward!).
• Protect your hair: The water is wonderful for your skin, but it can leave hair feeling like straw. Apply conditioner before you enter the pool and leave it in as a protective barrier while you soak.
• Use the Strætó bus: Navigate the city easily using the yellow bus system. Download the Klappið app to buy tickets and find the quickest route to your chosen pool in real-time.
• Get a Reykjavík City Card: The best value for explorers. It includes free admission to all public swimming pools and unlimited travel on the city buses.
• Limit your time in hot tubs: To avoid feeling lightheaded, take breaks from the hottest tubs (which can reach 44°C/111°F). Always stay hydrated using the free water fountains found poolside.
• Review age limits: Confirm entry requirements before you go. Sky Lagoon is for those 12 and older; Hvammsvík is for those 10 and older; public pools welcome all ages.
• Enjoy a post-pool snack: Complete the ritual. Grab a pylsa (hot dog) with everything or a bragðarefur ice cream from a nearby shop. If you’re downtown, wander over to Hafnartorg Gallery for some of the city's best bites,

Don't be afraid to ask for help. Staff are always ready to guide you through the lockers or the "naked shower" etiquette if it’s your first time.
