Natural spas and hot springs in Iceland

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.

Despite the name, this landmark geothermal bathing pool is far from a well-kept secret: in fact, it’s said to be the oldest hotpot in Iceland, and it’s very popular as it’s easily reached from Reykjavik, and makes an ideal stop for visitors tracing the Golden Circle.

A newcomer to the north coast, near Husavik, this excellent bathing pool complex combines mineral-rich seawater with heat from the Earth’s core.

The hot seawater pools, heated to 38˚C, are said to be good for psoriasis. The heart-stopping ocean views from the waters are good for the soul.

Myvatn Nature Baths at Jardbodin are known as the northern version of the Blue Lagoon – a large outdoor geothermal pool and steam room complex with views of Myvatn Lake.

This coastal pool was once well off the beaten track, but it’s becoming increasingly popular due to social sharing and Instagram. It’s certainly an impressive sight, with views over Drangey Island and Skagafjordur.

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.

An incredible infinity pool located way out in the Westfjords, on the wild Strandir coast overlooking a striking black sand beach. It’s accessed via a rough, unsealed track near Nordurfjordur.

For setting, the Sky Lagoon takes some beating. Opened in 2021, it’s framed between craggy rocks and looks right out to sea, making it feel like a natural feature (although it’s actually man-made).
