Best Geothermal Spas in Reykjavík & Surrounding Areas

Iceland's geothermal wonders have been soothing locals and visitors for centuries. With the capital region sitting atop one of the world's most active geothermal zones, Reykjavík and its surroundings offer an incredible variety of natural hot springs and luxury spa experiences.

 Whether you're seeking an authentic Icelandic tradition or a premium wellness retreat, these geothermal destinations will leave you rejuvenated and connected to Iceland's volcanic landscape.

1. The Blue Lagoon (Grindavík)

Located just 40 minutes from Reykjavík, the Blue Lagoon remains Iceland's most iconic geothermal destination. This man-made marvel was created by runoff from the nearby Svartsengi geothermal power plant, resulting in milky blue waters rich in silica, algae, and minerals.

The lagoon maintains a comfortable temperature of 37-39°C (98-102°F) year-round, making it perfect for soaking even during Iceland's harsh winters. The mineral-rich waters are renowned for their healing properties, particularly beneficial for skin conditions like psoriasis and eczema. Visitors can enjoy in-water massages, silica mud masks, and the lagoon's famous swim-up bar serving refreshing drinks.

Premium experiences: The Ble Lagouon offers several tiers of access, from standard admission to luxury packages that include private changing areas, premium skin care products, and access to the exclusive Retreat Spa with its own private lagoon.

2. Sky Lagoon (Reykjavík)

Opened in 2021, Sky Lagoon represents the newest addition to Iceland's geothermal spa scene. Perched on the Reykjavík peninsula with breathtaking views of the North Atlantic Ocean, this infinity-edge lagoon creates the illusion of floating above the sea.

The lagoon features a unique seven-step ritual called "Skjól," which combines Icelandic bathing traditions with modern wellness practices. This includes a cold plunge pool, sauna, steam room, and body scrub using Icelandic sea salt. The facility's modern Nordic design seamlessly blends with the dramatic coastal landscape, creating an almost otherworldly atmosphere.

Signature feature: The infinity edge design and ocean views make Sky Lagoon particularly magical during sunset, when the sky and water seem to merge in brilliant colors.

3. Vesturbæjarlaug (Reykjavík)

Nestled in Reykjavík's trendy Vesturbær neighborhood, this smaller geothermal pool offers an intimate and local atmosphere. With several hot tubs at different temperatures and a 25-meter swimming pool, Vesturbæjarlaug is perfect for those seeking a quieter geothermal experience.

The pool's location near the old harbor area makes it convenient for exploring Reykjavík's cultural attractions afterward. Many locals consider this their neighborhood gem, offering the same geothermal benefits as larger facilities but with a more personal, community feel.

4. Sundhöllin (Reykjavík)

Built in 1937, Sundhöllin holds the distinction of being Reykjavík's first indoor swimming pool. This Art Deco masterpiece combines historical architecture with modern geothermal amenities. The facility features a beautiful main pool, several hot tubs, and traditional steam rooms.

The building itself is a work of art, with its distinctive white facade and curved lines representing the golden age of Icelandic architecture. Swimming here feels like stepping back in time while enjoying the timeless pleasure of Iceland's geothermal waters. The central location makes it easily accessible from anywhere in downtown Reykjavík.

5. Nauthólsvík Geothermal Beach

For a truly unique experience, Nauthólsvík offers Iceland's only geothermal beach where you can bathe in the North Atlantic Ocean. Located on Reykjavík's southern shore, this golden sand beach is artificially heated using geothermal water, creating a surreal experience of warm ocean bathing.

The beach features both a naturally heated section of coastline and traditional hot tubs for those who prefer guaranteed warmth. During summer months, the ocean temperature can reach a surprisingly comfortable 15-19°C (59-66°F). Even in winter, brave locals take advantage of the heated areas for a truly invigorating experience.

Adventure factor: This is the perfect spot for those wanting to say they've swum in the North Atlantic while staying warm in geothermal waters.

6. Reykjadalur Hot Spring Thermal River

For nature lovers and hiking enthusiasts, Reykjadalur Valley offers the unique experience of bathing in a naturally occurring hot river. Located about 45 minutes from Reykjavík, this geothermal area requires a moderate 3-kilometer hike through stunning Icelandic countryside.

The reward is a natural hot spring river where you can soak in waters ranging from pleasantly warm to quite hot, depending on your position in the stream. The experience of bathing in a wild geothermal river surrounded by steaming vents and colorful mineral deposits is unforgettable. The hike itself offers spectacular views of geysers, mud pots, and the otherworldly landscape that makes Iceland famous.

What to bring: Waterproof bags for your clothes and towels, as changing facilities are basic. The hike can be muddy, so proper hiking boots are recommended.

7. Fontana Geothermal Baths (Laugarvatn)

Located on the shores of Lake Laugarvatn, about an hour from Reykjavík, Fontana offers a more intimate geothermal experience with stunning lake and mountain views. The facility features three interconnected outdoor pools with different temperatures, traditional Finnish-style saunas, and a unique steam room built over a natural hot spring.

What makes Fontana special is its connection to the surrounding landscape. After warming up in the geothermal pools, visitors can take a refreshing dip in the cool lake waters. The facility also offers the opportunity to taste traditional Icelandic rye bread, which is baked underground using geothermal heat in a centuries-old tradition.

Cultural experience: The bread-baking demonstration and tasting provides insight into how Icelanders have historically used geothermal energy for daily life.

Planning Your Geothermal Spa Journey

The best time to visit these geothermal spas is during the shoulder seasons (April-May and September-October) when crowds are smaller but facilities remain fully operational. Winter visits offer the magical experience of soaking in hot waters while snow falls around you, though daylight hours are limited.

Most facilities provide towel rentals and basic toiletries, but bringing your own ensures comfort and familiarity. Swimwear is required at all locations, and many Icelanders prefer minimal, functional swimsuits that dry quickly.

Whether you choose the world-famous Blue Lagoon, the community atmosphere of local pools, or the adventure of hiking to wild hot springs, Reykjavík's geothermal offerings provide the perfect way to experience Iceland's unique relationship with the forces beneath the earth.
