With distinctive red volcanic rock slopes, measuring 170 meters wide, 270 meters in circumference and 55 meters deep, Kerid crater lake is a 3,000 year old volcanic crater lake in South Iceland on the Golden Circle route. The actual lake itself is relatively shallow, between 7 and 14 metres, depending on rainfall and other factors, but as a result of minerals from the surrounding soil, the water is a unique and strikingly vivid aquamarine shade of blue. Take an easy hike around Kerid crater and enjoy the spectacular view!
Although there are other crater lakes in the area, Kerið is famous for being one of the lakes with the most caldera still intact. A unique factor about this crater is that it is (only) about 3000 years old, so is about half as old as the geological features that surround it! There’s an easy hike around the rim of the crater, so you can get really close if you like! Alternatively, there is a ladder down to the lake.
