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 Halnefjorden, a few hundred metres east of Halne mountain lodge, lie the remains of two stone sheds – Halnelægeret. Some generations ago the cattle drovers stopped here in the summer; they were the cowboys of their time. But Halnelægeret already had a long history before the cattle drovers came.
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.
After the ice age, Granvin Fjord reached all the way up under Skjervsfjossen waterfall. Just a thousand years later, as a result of the rising of the land after the ice melted, this whole inner part of the fjord freed itself of the sea and became Granvinsvatnet lake. In spite of this rise in elevation, this waterway is still navigable for fish: Sea trout have wandered into Granvinsvatnet in more recent times and evolved to become freshwater trout. And salmon and sea trout made the journey 13 kilometres up the Storelvi river.
Flowering lime is one of nature's blessings: The nectar gives clear honey. The flower is used as folk medicine. From the inner bark of the lime tree one can make strong rope. Elderly folk can still tell how they got a weather report from the lime tree. If it smelled strong, it was probably going to rain. Lime often grows together with elm, ash and other tree species of the deciduous forest. Pure lime forests are rarer. Granvin has Hordaland's biggest lime forests.
One of the most magnificent deciduous forests in Hordaland grows along the border with Kvam. The rich growth comes from the phyllite and mica schist bedrock, together with a good climate. Along the fjord the summer is warm but not too dry, and in winter it is not too cold for plants that do not tolerate the frost.
Folkedal, which today is like a small “detour” from the main highway, was in the Middle Ages centrally situated in one of the most important roads between Hardanger and Voss. This is the road that Olav Haraldsson travelled in 1023, when he came from the royal farm at Avaldsnes for a meeting with the Voss inhabitants about the new belief. The road passes across the mountain pasture Krossaset and down Bordalen to Vangen.
The old stone church at Eidfjord has an open position on the terrace at Lægreid. In a diploma from 1310 it transpires that Torgeir on Sponheim donated a gift for the erection of the church in Eidfjord. Thus we can assume that the church was under construction at the time. The elements in the style confirm such a dating.
