Kerið

Kerið is a volcanic crater lake located in the Grímsnes area of Southern Iceland. It is one of the most popular tourist attractions in the region, known for its striking turquoise-blue water set against a backdrop of red volcanic rock. The crater is approximately 55 meters deep, 170 meters wide, and 270 meters long. It is part of the Iceland's famous Golden Circle tourist route, attracting thousands of visitors annually.

The formation of Kerið is believed to be the result of a volcanic eruption that occurred around 3,000 years ago. After the eruption subsided, the magma chamber beneath the cone collapsed, forming the caldera. The lake itself is fed by groundwater, and its vibrant color is due to the mineral content of the water and the surrounding volcanic soil. While the water temperature is cool, swimming is generally not permitted to preserve the site.

Access to Kerið is typically via a path leading down to the lake's edge. Walking trails also encircle the rim of the crater, offering panoramic views. The site is privately owned and managed, and a small entrance fee is usually required for visitors. Kerið's unique geological features and picturesque appearance make it a significant natural landmark in Iceland.
