Dyrhólaey is a 120 m high tuya that was formed in at least two eruptions around 100,000 years ago.

Dyrhólaey was protected in 1978 by the Icelandic government for its great natural beauty, its birdlife and to maintain this popular tourist destination. The reserve covers an area of 147.2 ha. A ranger resides in the area year-round and handles the infrastructure, nature preservation and visitor education.
