Sky Lagoon sits on the edge of Reykjavík, where a long infinity edge seems to pour straight into the Atlantic. It is one of the easiest premium soaks to reach and a wonderful introduction to the Icelandic bathing rhythm.
What to expect
The signature here is the seven step ritual: warm lagoon, a brisk cold plunge, a sauna with a sea view, a cool mist, a gentle scrub, steam, and a final soak. Allow a couple of unhurried hours.
Getting there
About 15 minutes from central Reykjavík by car or shuttle, so it is easy to add to any city day.
Best time to visit
Glorious at sunset year round; winter evenings add a chance of the aurora over the water.
