Natural spas and hot springs in Iceland

  • Iceland

Last updated: 21 March, 2024

Like many Nordic nations, Icelanders are obsessed with bathing in the great outdoors – only here, they have the advantage that many of their favourite swimming spots are as warm as a bath.

Iceland is littered with natural hot springs, or ‘hotpots’, a by-product of the violent volcanic activity that’s continually roiling just beneath the island’s rocky crust. Some, like the Blue Lagoon and Myvatn Nature Baths, are very well-known – but there are hundreds more ‘hot pots’ hidden away deep in the countryside or along the coast which are known only to locals.

Bathing in the hot, mineral-rich waters is said to be good for the body and the mind. The naturally warm waters are especially rich in sulphur and silicate minerals – believed to be beneficial to skin conditions like psoriasis.

Bucket List Experience

Blue Lagoon

Iceland’s most popular – and photogenic – geothermal pool is surrounded by black lava fields and framed by the steaming towers of the Svartsengi geothermal plant. It’s an otherworldly place that looks like something out of a science-fiction movie – and an essential experience to tick off your Icelandic bucket list.

Averaging 37–39°C, the steaming pools are actually a by-product from the power plant, but don’t let that deter you. The waters are rich in minerals and silica, absorbed from the volcanic bedrock, a tonic for skin inflammation.

The psychedelic, blue-green water comes from naturally occurring algae which thrive in the balmy water.

  • Snaefellsnes Peninsula, Iceland

Lysuholslaug geothermal baths

Experience

Snaefellsnes has its own answer to the Blue Lagoon – and while the site isn’t quite as impressive, it’s still a soothing place for a dip. The water often looks a murky green from the minerals and algae, but don’t fret – it’s completely clean, and warm as a bath.

Getting there & doing it

The better-known pools are easy to find, but you’ll need a local guide and/or a decent map to find the more secret ones.

Not all of Iceland’s hot pots are safe to bathe in (some are just too hot, others have unpleasant minerals in them), so it’s not a good idea to just jump in unless you know what you’re doing.

When to do it

Theoretically, you can bathe in the hot pools at any time of year. Many people come for the unique experience of bathing under the Midnight Sun, but midwinter is in some ways even more atmospheric – it’s an unforgettable experience to sit back in the piping hot water and simultaneously watch the snow falling all around.
