Best Geothermal Pools and Hot Springs in North Iceland: From Mývatn Nature Baths to Secret Spots

Discover North Iceland's most rewarding geothermal bathing experiences, from the milky-blue Mývatn Nature Baths to tucked-away natural hot springs where you'll soak surrounded by Arctic wilderness.

Mývatn Nature Baths: North Iceland's Crown Jewel

The Mývatn Nature Baths near Reykjahlíð offer a quieter, more intimate alternative to the famous Blue Lagoon, with the same milky-blue geothermal water rich in minerals. Set against a dramatic backdrop of lava fields and steaming vents, this lagoon maintains a temperature of 36-40°C year-round and draws mineral-rich water from a borehole nearly 2,500 metres deep. The facility includes changing rooms, a steam bath carved into a lava cave, and a small café serving Icelandic snacks.

Visiting Mývatn Nature Baths works best as part of a full day exploring the Lake Mývatn area, which includes the Hverir geothermal area, Dimmuborgir lava formations, and Grjótagjá cave. Staying overnight in Reykjahlíð or nearby Akureyri gives you flexibility to visit the baths during quieter morning or evening hours when day-trippers from other regions have left. Booking accommodation in Akureyri, Iceland's northern capital just 90 minutes away, provides a comfortable base with restaurants and services while keeping you close to North Iceland's geothermal wonders.

GeoSea Geothermal Sea Baths in Húsavík

Perched on a hillside overlooking Skjálfandi Bay in Húsavík, GeoSea offers a unique experience where geothermal water meets ocean views. The infinity-edge pools use naturally heated seawater drawn from boreholes below the town, rich in minerals and maintained at a comfortable bathing temperature. From the pools, you'll watch fishing boats return to harbour, and if you visit between May and September, you might spot humpback whales breaching in the bay below.

Húsavík is Iceland's whale-watching capital, and pairing a morning whale-watching tour with an afternoon soak at GeoSea makes for an unforgettable day. The town offers several guesthouses and hotels within walking distance of both the harbour and GeoSea. For those exploring the Diamond Circle route through North Iceland, Húsavík serves as an ideal overnight stop between Lake Mývatn and the Ásbyrgi canyon.

Secret Natural Hot Springs Worth Finding

Grjótagjá cave, made famous by a Game of Thrones filming location, is a small fissure with a stunning blue geothermal pool inside a lava cave near Lake Mývatn. While the water is now too hot for safe bathing (around 50°C), the cave remains worth visiting for its otherworldly beauty and geological significance. For actual bathing, locals head to Stórагjá, a similar fissure pool about 1.5 kilometres east of Grjótagjá, where temperatures hover around a more comfortable 38-43°C and bathing is permitted in designated areas.

The Laugafell hot spring in the Highlands northeast of Varmahlíð offers true isolation for adventurous travellers with 4x4 vehicles, though it's only accessible during summer months when Highland roads open. Closer to main routes, the Hveravellir geothermal area between Reykjavík and Akureyri features simple natural pools where you can bathe surrounded by steaming fumaroles and colourful mineral deposits. These off-the-beaten-path experiences require more planning and appropriate vehicles, but reward you with a sense of discovery that crowded tourist pools cannot match.

Forest Lagoon: Akureyri's Newest Geothermal Experience

Opened in 2021, the Forest Lagoon sits on a hillside above Akureyri with sweeping views across Eyjafjörður fjord. This modern facility blends seamlessly into the birch and pine forest, with an infinity edge that creates the illusion of the warm water flowing directly into the fjord below. The lagoon uses geothermal water from boreholes in the Vaðlaheiði tunnel, and the on-site bar serves Icelandic beer and light refreshments you can enjoy while soaking.

Akureyri makes an excellent base for exploring all of North Iceland's geothermal attractions, with comfortable hotels, supermarkets, and restaurants that smaller villages cannot offer. The town sits roughly equidistant from Mývatn Nature Baths to the east and the Tröllaskagi peninsula hot springs to the west, putting you within an hour's drive of numerous bathing options. After days spent driving the Diamond Circle or exploring remote hot springs, returning to a proper hotel in Akureyri provides welcome comfort and convenience.

Practical Tips for Geothermal Bathing in North Iceland

Iceland takes pool hygiene seriously, and all public bathing facilities require you to shower thoroughly without a swimsuit before entering the pools. Bring your own towel and swimsuit, as rental fees at popular sites can add up quickly. Natural hot springs have no facilities whatsoever, so pack everything you need including water, snacks, and a towel. Check temperatures before entering any natural pool, as some geothermal areas have dangerously hot water that can cause serious burns.

Winter bathing offers a magical experience when you can soak in 38°C water while snowflakes land on your face and the Northern Lights dance overhead, but roads to remote hot springs become impassable from October through May. Summer brings midnight sun bathing opportunities, with enough daylight to visit pools at 11 PM when they're nearly empty. Booking accommodation in towns like Akureyri, Húsavík, or Reykjahlíð gives you the flexibility to visit geothermal sites at different times and return to comfortable lodging after long soaks in the mineral-rich waters.

Questions, answered

What's the difference between Mývatn Nature Baths and the Blue Lagoon?

Mývatn Nature Baths in North Iceland offers a similar milky-blue geothermal bathing experience to the Blue Lagoon near Reykjavík but with fewer crowds, lower prices, and dramatic lava field surroundings. Both use mineral-rich geothermal water, but Mývatn feels more intimate and less commercialised, making it ideal for travellers exploring the Diamond Circle route who want a premium geothermal experience without the tour-bus atmosphere.

Can you safely bathe in all of Iceland's natural hot springs?

No, many natural geothermal pools in Iceland are dangerously hot and unsuitable for bathing. Always check the temperature before entering any natural spring, and never enter water that's steaming heavily or lacks other bathers. Stick to well-known bathing spots like Stórагjá near Mývatn or maintained facilities like Mývatn Nature Baths and GeoSea for safe, comfortable temperatures. Grjótagjá cave, despite its fame, is too hot for bathing and posted as such.

Where should I base myself to visit North Iceland's hot springs?

Akureyri offers the best combination of accommodation options, restaurants, and services while positioning you within 60-90 minutes of most North Iceland geothermal sites including Mývatn Nature Baths, GeoSea in Húsavík, and Forest Lagoon. For those focusing specifically on the Lake Mývatn area, staying in Reykjahlíð puts you right next to Mývatn Nature Baths and numerous natural hot springs, though with fewer dining and shopping options than Akureyri provides.
