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.
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.
Hardangerfjorden kløyver Hordaland i to. Den etter måten rettlinja fjorden skjer seg liksom på skeive inn i landet. Ikkje som Sognefjorden og Nordfjord – dei krokar og buktar seg innover meir eller mindre vinkelrett på kysten. Hardangerfjordens utforming har røter 400 millionar år tilbake i tida, då den veike sona i fjellet, der isen seinare tok grådig for seg, vart danna. Denne sona stig på land ved Lussand.
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.
They rest there, all as one, the silent witnesses of Western Norway's saga of creation: Precambrian basement, phyllite and thrust sheet. In the end came the glaciers and sculptured the vast landscape. Along the ground or on the horizon, from bicycle or on foot - the landscape tells its story - and it tells it clearer on Rallarvegen than many other places.
When the lush beach area innermost in Ulvikapollen was protected, the bird life was instrumental to the decision. The plant diversity is just as impressive. In Hordaland sea meadows such as this are rare small in size - they are more common in coastal environments.
There are especially many seabirds inwards along the fjords of western Norway. There are not many islets, either, so if the birds want to nest, it is not always easy to find good sites. At Aksnesholmane there is an impressive colony of gulls, and the locality has been protected since 1923.
