Evanger (from Old Norse ålvangr, “vang”, “voll” (field) where the horses may graze) is the place where the river from Vangsvatnet, the Voss watercourse, runs out into Evangervatnet. From here Teigdalen valley runs to the north, towards Eksingedalen, and from here there is a short distance to Bergsdalen in the south.
The permanently-protected Mosneselva River, with its meltwater from Folgefonna, runs out into Åkra Fjord by the roadless and uninhabited Mosnes. Those who once lived here were forced to surrender to the ravages of Nature. In the autumn of 1962 there was a flood so great that the people were driven from their farms.
