At 13.6 square kilometres (5.3 sq mi), it is the largest island in the municipality.
The village of Myklebost is located at the south end of the island, where there are ferry connections to Dryna (in Midsund) and Brattvåg and Fjørtofta (in Haram).
Harøy Church is located in the center of the island,[2] just north of the Lomstjønna Nature Reserve.
