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.
A barren belt where almost nothing grows, runs through the forest on the east slope of Gullbotnen. But, along the west side of the main road there is a fertile zone that flourishes with several finicky plant types. The contrasts arise from the extreme variations in the nutrient content of the bedrock.
Few other places in Hordaland, or even the whole country, get as much rain as in the Samnanger mountains. The mountains here simply attract wetness. The weather station on Kvitingen has continuous measurements all the way back to 1900, and the measurements have documented several records for the county. The station is therefore much used as a reference for the rainfall in western Norway.
