Aðalvík is a 7 km wide inlet at the extreme (west) end of Hornstrandir. There used to be the fishing villages of Látrar and Sæból, but the settlements were abandoned in the middle of the 20th century. The last inhabitants moved from Látrar and Sæból in 1952.
The British military built a base on Mt. Darri about Aðalvík, the remains of which you can still see; an anti-aircraft gun, buildings, and a road. West of Látri on Straumnesfjall, military structures were built in 1953, the remains of which can still be seen. An airport was also built inside the village.
Hornstrandir is one of the most beautiful places in Iceland. There are no roads and sporadic cell reception, so you might experience complete tranquillity without interruptions – apart from bird songs and the Arctic fox. You must be well prepared for the hike, but it is well worth it!
