Kleifarvatn is the largest lake on the Reykjanes Peninsula, known for its eerie beauty and geological intrigue. The lake is fed solely by groundwater, with no visible rivers flowing in or out, adding to its mystique. Following a significant earthquake in 2000, the lake's water level dropped by about 20%, revealing geothermal vents along its southern shore. Since then, the lake has partially refilled, but the event left a lasting mark on the area.​
