Hraunhafnartangi and Rifstangi are the northernmost points of Iceland, at the edge of the arctic circle. Hraunhafnartangi derives its name from the natural harbor which is mentioned in 13th-century literature. Þorgeirsdys, a stone mound found on Hraunhafnartangi, is believed the burial mound of Þorgeir Hávarsson who was slain there in an epic 11th-century battle chronicled in Fóstbræðrasaga.

Visitors who bring pictures of themselves by Hraunhafnartangi lighthouse can receive a certificate from local service providers of having been to the northernmost point of the Icelandic mainland.

A sign on the gravel road No. 870 indicates to the most northern point of the mainland of Iceland. A short walk follows the coast with a rich birdlife. The Arctic Circle lays just 3 km further north. Please be very careful, if you climb up the huge stones to "see" the Arctic Circle - the ocean sometimes sends strong waves and stones are slippery.

The elder duck is protected under Icelandic law. All access to the nesting area and its surroundings is prohibited between April 15th and July 14th.
