Furthest north in the island community Rongevær, at the entrance to Fensfjorden, lies Krossøy. Belonging to the farm are the islands of Krossøy, Husøy, Kårøy, Lyngkjerringa, Søre Kjerringa, Rotøy and Kuhovet. All of them have been inhabited. On Krossøy itself today there are four holdings. The marine use environment here is one of the best preserved along the West Norwegian coast.
Bruosen is one of the few river harbours in the county. As landing place for the churchgoers, this place and the boatshed environment follow a tradition that goes back to the Middle Ages, but the country store of today is much younger.
