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.
In the sunny, steep fjord landscape along Sørfjorden on the east side of Osterøy is the farm Havrå. The small “hamlet” is one of the few undisturbed farming communities that gives us the impression of the large communal yards in West Norway in the 1700s, with houses built close together and strips of arable land.
The troll-like sounds from the Red-throated diver carry long distances between the mountains around Storavatnet. The high-pitched, haunting screeches on quiet evenings in May are a sign that the mating season has begun.
