Bjoreidalen is one of the classic bird localities on Hardangervidda. It is especially known for its wading birds, with as many as 17 of the 19 wader species that nest in Hordaland.
At Fruo, nature has built its own little "Chinese wall ". Some kilometers south of the Vøringsfossen waterfall, there are a number of moraine ridges, the longest and most notable of their kind in Hordaland.
The Eidfjord terrace is a gigantic ridge that reaches up more than one hundred metres from the city centre in Eidfjord. It serves as a powerful natural monument left behind by the ice when it retreated.
The Ruff lek on Langvassmyrane is the only known phenomenon of its kind on Hardangervidda. Every year it attracts hens from the whole plateau. The marsh is also the richest wetland in the county. This green oasis is located in a rocky moraine landscape a few hours walking distance south of Dyranut.
Much of the sand and gravel that the town of Etne is built on was laid down at the end of the Ice Age and is evidence of melting glaciers and roaring meltwater rivers. The uncompacted material in the big terraces leave their unmistakeable mark on the wide elongated valleys.
In Skånevik there are marks left from the ice edge that advanced during the thousand-year cold spell (Younger Dryas) that marked the end of the Ice Age roughly 11 500 years ago. The glacier first proceeded out into Åkra Fjordand and around Vannes and thereafter sent an arm in toward Skånevik. Here, the glacier lay down an end moraine up against the mountainside.
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.
