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.
Solskinstjørni in Osa, just above Haugen farm in Norddalen, is visible only now and again, seemingly always for a period of good weather. Then it disappears abruptly, but its disappearance is not connected to weather conditions.
The steep drop by Fossen cliff has been the biggest challenge for those who wished to make a road over Kvamskogen through the years. Leave the car by the monument on the old road and take a walk down to the bend by the waterfall that Bergen-folk call "The bridal veil". Why is there a waterfall just here?
Much rain, a steep drop and nearness to Bergen meant that the power-making potential of the Samnanger water system was exploited early. Samnanger was thus one of the first power-producing municipalities in western Norway. With its subsequent expansion and new power stations, about 400 gigawatts of electricity per hour were produced on average each year. This is enough to meet the energy needs of 25,000 households.
One does not need much imaginationto see that where the river bends down in Røssebotnen, there has once been a lake. The landscape tells this - more clearly than any book.
