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.
