Matrehola
On a large gravel terrace in Matredalen (the Matre valley), a couple of kilometres from the coastal settlement Matre, lies Storseterhilleren, at the end of a large stone block that came rushing down from the mountain. The Matre river runs just over 100 metres to the east of the cave.
Lonelva
It is said that the salmon populations with the largest and the smallest salmon in the world both come from the waters that run out into the fjord system around Osterøy. Vosso is supposed to have the largest spawning salmon to be found in any river, whereas Lonelva is said to have the smallest.
Storavatnet- Red-throated diver
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.
Årbakka- The prehistoric site
The prehistoric site at Årbakkasanden with menhirs and burial mounds has been visited, described and illustrated by many learned researchers through the last 350 years. All the same, we still know very little of this unique cultural monument.
Frøyset river network
Frøyset river network is protected from power station-building - not because of its pristine nature - but because it is a typical river network for this part of western Norway.
