Keriðs

Kerið is a volcanic crater lake located in the Grímsnes area of Southern Iceland. It is one of the most popular tourist destinations in the region, known for its striking turquoise water and the vibrant red volcanic rock that forms its caldera. The lake itself is approximately 55 meters deep, 170 meters wide, and 270 meters long. The water level fluctuates depending on rainfall and groundwater.

The crater is believed to have formed approximately 3,000 years ago. Unlike many other volcanic craters, Kerið is not the result of an explosive eruption. Instead, it is thought to have formed when a magma chamber beneath the volcano emptied and the overlying structure collapsed. The surrounding rocks are composed of a dark, porous lava. A thin layer of water has accumulated in the crater over time.

Visitors can walk around the rim of the crater, which offers panoramic views of the lake and the surrounding landscape. A set of stairs provides access down to the water's edge, allowing for a closer inspection of the colorful mineral deposits and the water itself. The volcanic nature of the site is evident in the distinct geological features. Kerið is privately owned and a small entrance fee is typically charged for access.
