Blue Lagoon, Sky Lagoon or a local pool?
The Blue Lagoon is the famous one and the most expensive. Sky Lagoon is closer to Reykjavik. A town pool costs about a tenth as much and is what Icelanders actually use.
Blue Lagoon
On the Reykjanes peninsula, about 20 minutes from the airport and 45 from Reykjavik. Milky-blue silica water, big changing facilities, silica masks and in-water bars. Entry is time-slotted and must be booked well ahead; it is the priciest option by a wide margin. Best used on your arrival or departure day, since it sits between the airport and the city. Opening can be affected by volcanic activity in the area — check before you travel.
Sky Lagoon
In Kópavogur, roughly 15 minutes from central Reykjavik. An infinity edge facing the Atlantic and a seven-step bathing ritual. Cheaper than the Blue Lagoon, far easier to reach without a car, and excellent at sunset or in the dark. This is the best choice if you only have a city break.
Regional alternatives
- Mývatn Nature Baths in Mývatn — similar feel to the Blue Lagoon, a fraction of the crowds, superb for aurora watching.
- Forest Lagoon and Beer Spa near Akureyri — woodland setting overlooking the fjord.
- Secret Lagoon and Fontana around the Golden Circle — small, historic and easy to combine with sightseeing.
- Sky-high value: Vök Baths near Egilsstaðir — floating pools on a lake in the east.
Town swimming pools: the local answer
Every Icelandic town has a geothermal pool with hot tubs and often a steam room, for roughly 1,200–1,500 ISK. Laugardalslaug and Vesturbæjarlaug in Reykjavik are institutions. Shower thoroughly without swimwear before entering — this is strictly observed and not optional.
