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.
On the farms Kjerland and Røynstrond, east of the river that flows into the fjord, we find many decorative painters who belong to the so-called sòlekistemålarane in Hardanger: Knut and Mikkjel Røynstrand and Johannes Jonsson Kjærland.
In the Middle Ages the farmers were under obligation to transport state officials. The bishops were entitled to 18 horses when they travelled about on visitations, and the king could requisition free transport.
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.
The road along the north side of the Hardanger fjord - between Øystese and Eide in Granvin – was literally built “by hand”. The construction work started in February 1933, and on 9 October 1937 Crown Price Olav opened the stretch of road between Øystese and Ålvik at Fyksesund bridge.
For many years the Folkedal scythe had a good reputation. Immediately above the highway through Folkedal there is a long brick building, on the inner side of the river. Here production of scythes went on to the beginning of the 1950s.
