Grødalshaug
At the bottom of Vargavågen on Halhjem lies Grødalshaug, a 30 metres high rocky outcrop between the bay and a moist valley cleft. On the south side of the rock is a steep rock cliff facing the valley, the bog and the stream. On this rock face we find rock carvings from the Bronze Age.

Oselva
Oselvo is the biggest waterway on the Bergen peninsula, with sources in Gullfjellet and Sveningen. There is a fall of only 60 metres along the entire stretch from Samdalsvatnet Lake to the sandbank in Fusafjorden. It is rare to see a river like this in western Norway. There is salmon along this entire section of the Oselvo river.
