About Lake Kleifarvatn
Lake Kleifarvatn is Iceland's geothermal lake dive on the Reykjanes Peninsula, with a black-sand shore entry, bubbling hot-spring craters, and a volcanic landscape that makes the site feel more otherworldly than recreational. It is a cold-water shore dive where current checks, water-level checks, and drysuit planning matter as much as the dive profile.
