Kerið, a 55 m deep explosion crater about 3,000 years old, in Tjarnarhólar, a group of crater–hills. A must for sightseers. The story goes that when the water level rises in Kerið, it falls to an equal extent in the small lake on the mountain Búrfell in the Grímsnes district, and vice versa. A protected natural feature.
