Lagoon Land

A guide to Iceland’s geothermal lagoons

Born out of fire, made for bathing.

Iceland is a volcanic island, warmed from below, and people have bathed in its hot water for over a thousand years. Today that water fills some of the world’s most beautiful lagoons, by the sea, in the forest and high in the mountains.

What’s new

Opened and reopened

Iceland is in the middle of a lagoon boom. Here’s what has opened, or been rebuilt from the ground up, in the past twelve months.

The boom isn’t over. These are the next openings to look forward to.

Lagoon science

Hot water, cold island

Iceland sits on a seam in the planet: the Mid-Atlantic Ridge, where two tectonic plates are slowly pulling apart. The same forces that keep splitting the island open, around thirty active volcanic systems, also heat the water underneath it, and Icelanders have been bathing in it since the first settlers arrived. In the 1200s the saga writer Snorri Sturluson had a stone-lined hot pool at his farm in Reykholt. Snorralaug is still there, and you’ll find a copy of it at Sky Lagoon.

What has changed is the scale. Over the past few years a new generation of geothermal lagoons has opened all around the country: ocean-edge infinity pools, baths in birch forests, pools that fill and empty with the tide, baths floating on a lake, and pools fed by a road tunnel. Older favourites have been rebuilt and expanded, and a few small local baths carry on much as they always have.

Lagoon Land gathers every one of them in one place. Use the map to see where they are, read why each one is worth the drive, and book your visit when you’re ready.

Where the water comes from

Found by accident

A road tunnel that hit a hot-water vein, seawater too mineral-rich to heat houses, a power plant’s run-off pond. Some of the best lagoons were never planned.

Litli Geysir

All of Secret Lagoon’s water comes from the hot springs around it, and a little geyser at the edge of the field erupts every few minutes.

Lagoon etiquette

  1. 1

    Shower first, without your swimsuit

    It’s the house rule at every Icelandic pool and lagoon, and attendants do keep an eye out. Many lagoons have private cubicles.

  2. 2

    Book a time slot

    Nearly every lagoon sells timed entry. Sunset in summer and evenings in aurora season sell out first.

  3. 3

    Look after your hair

    Silica and minerals are lovely for skin and hard on hair. Condition well, and keep your head above water.

  4. 4

    Leave the silver at home

    Sulphur in geothermal water tarnishes silver and copper. Take off rings and jewellery before you get in.

  5. 5

    Drink water

    Hot water dehydrates you faster than you’d expect. Use the drinking fountains and go easy at the swim-up bar.

  6. 6

    Dress for the walk

    In winter the walk from the changing rooms can be well below freezing. Bring flip-flops and a robe.
