The main population and administrative centre of the municipality is the town of Fosnavåg, located on the island of Bergsøya. The municipality is entirely composed of islands located north of the Rovdefjorden. It includes the main islands of Bergsøya, Leinøya, Nerlandsøya, Remøya, Runde, Skorpa, Flåvær, and the eastern part of Gurskøya, plus many smaller islands. The island of Runde is especially notable for its large seabird colonies (and Runde Lighthouse), while Skorpa is famous for its role as a station for the Shetland bus. The islands are connected together via a series of bridges including the Runde Bridge, Remøy Bridge, Herøy Bridge, and Nerlandsøy Bridge.
