Flateyri on the bay Önundarfjörð has been a trading post since 1792, and temporarily became a major whaling center in the 19th century. The nature at and near Flateyri is worth exploring.

Geologically this is considered to be the oldest part of the West. In October 1995 an avalanche hit the village, destroying 29 homes and killing 20 people. Since then a deflecting dam has been built to protect the village from any further avalanches.
