If there’s one thing an Icelander is qualified to write about, it’s where to get warm in cold water. We invented the concept. Every town in this country has a pool. Every valley seems to have a spring.

Snow-covered mountains stretch across the horizon, contrasting with the deep blue waters of the ocean. The bright sky and soft clouds add to the serene atmosphere, highlighting the peacefulness of this unique spa experience, where warm geothermal waters meet the crisp Arctic air."

Over the years on Stuck in Iceland, I’ve written about a lot of them — the famous lagoons, the hidden farm pools, the local sundlaug network that visitors almost never discover. What I didn’t have was a single place that listed them all together, so you could plan your whole trip around getting warm.

Now I do. It’s live, and it’s the most comprehensive guide I’ve ever put on this site.

Book a hotel and a flight to Iceland

Vök Baths in East Iceland — the only spa in the country where the pools literally float on a lake. Naturally, hot water bubbles up through the surface of Lake Urriðavatn, and you can slip between the warm pool edge and the cold lake water on the same visit.

What’s in it

55 hot springs, geothermal spas, and swimming pools across Iceland, grouped into four categories: premium commercial spas, wild hot springs, Reykjavík area pools, and notable pools around the country. Every entry has GPS coordinates you can paste straight into Google Maps, plus my honest take on what it’s actually like to visit.

No fluff. No “world-class luxury destination” copy. If a pool is small and rustic, I say so. Is a famous lagoon worth the crowd? I say so. If a wild spring takes a four-hour hike to reach, I tell you that too.

The Secret Lagoon (Gamla Laugin) offers an authentic geothermal bathing experience away from the crowds, with naturally heated water maintaining a comfortable 38-40°C (100-104°F) year-round. Iceland’s oldest swimming pool dates back to 1891.

The good stuff

You’ll find the big names — Sky Lagoon, the Blue Lagoon, and Mývatn Nature Baths. You’ll also find things most guides skip: the Hofsós infinity pool at the edge of the Arctic, the three free hot tubs on the beach at Drangsnes that the village maintains itself, the 1891 Secret Lagoon, and the historic Seljavallalaug tucked under Eyjafjallajökull.

Friends toasting with champagne and beer in a geothermal pool at Hvammsvík Hot Springs in Hvalfjörður, Iceland.
Hvammsvík Hot Springs in Hvalfjörður — a cold beer or a glass of bubbly in a warm pool by the sea is one of the more civilized things you can do in Iceland. The bar serves you straight from the poolside. An hour from Reykjavík, and ten percent off for Stuck in Iceland newsletter subscribers.

Save on the premium spas

Five of the spas in the guide are Stuck in Iceland partners: Hvammsvík, Krauma, Secret Lagoon, Vök Baths, and GeoSea. Newsletter subscribers get exclusive discount codes for all five, ranging from 10% to 15% off.

A couple relaxes in one of Krauma Spa’s geothermal pools, toasting with drinks as steam rises in the background. The modern outdoor spa, surrounded by Iceland’s scenic countryside, features sleek black stone pools with natural hot spring water from Deildartunguhver. A sign indicates the pool’s temperature of 40-41°C (104-106°F), while lounge chairs and greenery enhance the tranquil atmosphere.
Relax to the max at Krauma.
