Iceland is a thermal country. Geothermal water heats the houses and fills the swimming pools and pours into geothermal lagoons designed by some of Europe's best architects. Our 5 Icelandic Curator's Picks include the Blue Lagoon (yes, even though), Sky Lagoon (yes, especially), and three lagoons most travelers never reach.
"The water comes out of the ground at 85 degrees Celsius. We have to cool it before we can swim in it."
Iceland's thermal bathing tradition runs through the whole society. Every town has a public swimming pool with hot tubs (heitir pottar) where the country's politics gets decided. The destination lagoons (Blue Lagoon, Sky Lagoon, Myvatn Nature Baths, Secret Lagoon) are tourist-priced; the public pools are not.
Our gold list is the destination tier. The next tier (Sundlaug Reykjavíkur, Vesturbæjarlaug, Laugardalslaug, Seltjarnarneslaug) is in the app for free. Use both: the destinations for the photo, the public pools for the actual local-life experience.
