Kerið Crater Lake is a picturesque (and overlooked) rest stop along the Golden Circle in Iceland.
Kerið Crater is located in southern Iceland, along the popular golden circle. It is about 15km north of Selfoss, off of highway 35.
The caldera was formed not by an explosion, but by the depleting levels of magma which collapsed the volcanic cone into the emptied magma chamber. The brightly colored, sapphire water at the bottom of the crater is about the same level as the water table and is not the result of rainfall. The red earth surrounding the crater lake is also a beautiful contrast to the water at the bottom.
The crater is about 55m deep and 3,000 years old.
There is an entrance fee of ~400 IKR. Enjoy the short walk around the crater and one down into the caldera.
