Lake Kleifarvatn

Lake Kleifarvatn is a beginner-friendly freshwater dive site on Iceland's Reykjanes Peninsula, located in a hauntingly beautiful volcanic landscape. This deep lake sits within an active geothermal zone, with hot springs bubbling up from the lava rock bottom, creating otherworldly scenes of rising gas bubbles and shimmering heat distortion underwater. The visibility varies but can be exceptional, revealing the lake's dramatic volcanic substrate of dark lava rock formations, fine black sand, and geothermal vents. While marine life is minimal—limited to arctic char and stickleback—the geological experience is utterly unique. The lake's surface is surrounded by barren lava fields and mountains, adding an almost lunar atmosphere to the dive experience. Dry suit certification is essential as water temperatures are cold year-round. Lake Kleifarvatn offers one of Iceland's most unusual diving experiences, a geological adventure where the Earth's volcanic forces create an underwater landscape found nowhere else.
