Búðir is the name of the village located at the inner end of the 15-km-long Fáskrúðsfjörður fjord.
Búðir was the main port for French fishermen in East Iceland both prior to and well after the turn of the century. At Búðir there was a French consul, a French hospital and a French chapel.
The mountain slopes in Fáskrúðsfjörður are partially grown with bushes, including wild aspens on the north coast.
Sandfell mountain is a cone-shaped, rhyolite mountain on the south side of the fjord, rising to a height of 743 meters. When molten rhyolite lifts older layers of lava, so-called laccolith is formed. Sandfell, about 600 m thick, is a famous example of this and is in fact one of the best visible examples of the Tertiary period in the northern hemisphere. A hike to the top of Sandfell is extremely enjoyable and takes 2-3 hours.
Skrúður is a grassy but rockbound island east of Fáskrúðsfjörður. It has an abundance of bird life, including puffins, kittiwakes, various black birds from the Alcidae family, gannets, storm petrels and Leach´s petrels. Skrúðshellir cave at Skrúður is the largest "puffin cave" in the world.
