At the bottom of the Osa fjord there is a cultural landscape marked by great contrasts; the wide terraces and the river delta at the fjord contrast with the steep hillsides in the background, where Norddalen leads up to the mountain. There are two farms here. Osa and Sævartveit – the farm at the river mouth and the hollow by the sea.
There is no place in Hordaland where there are so many over-wintering song swans as in Tjeldstømarka. And there are few places in the county that have had this birdfowl as a guest for as long.
