Sky Lagoon

Sky Lagoon is a geothermal spa on the shore at Kársnes Harbour in Kópavogur, the town that borders Reykjavik to the south, within easy reach of the capital. It opened in 2021 and offers a large outdoor lagoon of warm geothermal water at around 38 to 40 degrees, with an infinity edge that seems to merge with the sea.

The setting is the main attraction. From the water you look out across the North Atlantic, and on clear days you can see distant mountains, including the glacier-capped volcano Snæfellsjökull and the peak of Keilir. The design draws on Icelandic landscape and building traditions, with turf walls and a turf house, a cave-like tunnel entrance and colours chosen to echo the grey-blues, greens and creams of the surrounding nature.

The signature experience is the Seven-Step Ritual, a sequence that alternates warm and cold water, dry heat and fresh air. Its stages include a cold plunge, a sauna, a cold mist, a body scrub and a steam room, and the whole sequence is designed to relax and refresh, so take it slowly and finish with more time in the lagoon.

Sky Lagoon suits couples, friends and anyone who wants the geothermal bathing experience without travelling far from Reykjavik. It is especially atmospheric at sunset and, in winter, after dark, when you may be lucky enough to see the northern lights on a clear night. Booking a time slot in advance is strongly recommended, particularly at weekends and in summer, and the website lists the packages, age rules and current opening hours.

Weather is part of the experience: soaking in warm water while wind, rain or snow blow across the lagoon is something many visitors remember most. Wear flip-flops between the changing rooms and the water if you have them, and keep your phone in a waterproof pouch or leave it in your locker.

Kópavogur is a short drive or bus ride from central Reykjavik, and transfer options are listed when you book. Bring a swimsuit; as in all Icelandic pools and lagoons, you shower without a swimsuit before entering the water. Remove jewellery, tie up long hair to protect it from the minerals, and drink plenty of water. Allow two to three hours in total for the visit.
