Dyrholaey is a 120 m high and precipitous headland. A large, natural gate has been eroded through its southernmost part. When the sea is calm, big vessels can sail through it and in 1995, two adventurers flew in a small aircraft through it. The view from the highest points of the headland, where the 1927 lighthouse is standing, is excellent on a fine day.
In earlier times fishing outfits were operated from the lower parts of the promontory and ideas about a harbour construction there have been weathered. South of the promontory are freestanding cliffs in the ocean, one of which looks like a petrified elephant. It is highly interesting to watch the bird life in the cliffs, especially the puffins. English fishermen and sailors called the promontory Portland or the Blow Hole.
Dyrholaey is on the Saga trail for South Iceland.
