Kleifarvatn
Considered one of the best diving spots in Greeland, Kleifarvatn is the largest lake on the Reykjanes peninsula, covering an area of eight square meters. It is about 30 kilometers outside of Reykjavik and has a maximum underwater depth of 90 meters. Kleifarvatn Lake is surrounded by a stunning volcanic landscape of steep, vibrantly colored hills and strange lava formations. It's hard to believe that a populated city is only 30 minutes away from the lake's edge.
On one side of the lake, underwater hot springs were recently discovered about 10 meters from the shore. A large crater in the center of the hot springs spews large amounts of warm water and gases. The pressure created by the air bubbles pushing through the crater on the lake floor causes the surrounding rocks to vibrate slightly. Divers can usually sense these vibrations, which is a unique experience! Because the lake partially freezes over during the winter, diving and fishing activities are suspended.
