Grødalshaug

At the bottom of Vargavågen on Halhjem lies Grødalshaug, a 30 metres high rocky outcrop between the bay and a moist valley cleft. On the south side of the rock is a steep rock cliff facing the valley, the bog and the stream. On this rock face we find rock carvings from the Bronze Age.

Lysekloster- The monks and nature

Lysekloster was the largest agricultural property in the country when it was phased out during the Reformation in 1537. In its prime this cloister encompassed two-thirds of all the farms in Os. The monks introduced and cultivated new plant species and it was probably they who stocked the waters with fish not indigenous to the area. This legacy from the Middle Ages has left a lasting mark.

Oselva

Oselvo is the biggest waterway on the Bergen peninsula, with sources in Gullfjellet and Sveningen. There is a fall of only 60 metres along the entire stretch from Samdalsvatnet Lake to the sandbank in Fusafjorden. It is rare to see a river like this in western Norway. There is salmon along this entire section of the Oselvo river.

Ulven

In the region of Ulven phyllite occurs with Hordaland's youngest fossils, and a beautiful quartz conglomerate. The phyllite and conglomerate got squeezed into the bottom of an ancient oceanic crust, made of gabbro and greenstone, in the heart of the Caledonide mountain chain.

Sandviksfjellet

On Sandviksfjellet there are old boulders that have been made into mountains. The stones have been stretched out or squeezed together between huge slabs of rock, during slow, but powerfulprocesses of transport. This conglomerate shows, in quite a special way, the enormous powers that were active during the collision between Norway and Greenland over 400 million years ago.

Rambjøra

In Sanddalen and Helldalsåsen the building of houses has increased dramatically. Where there eariery was grazing land, hundreds of families now live. Not far away, lies Rambjøra as an oasis in the built up area.

Møkstrafjordøyane

The sea keeps the bedrock in the outer skerries smooth and clean. When the bedrock is also varied and interesting, the setting is perfect for a discovery tour of these bare-faced outcrops.

Hårteigen

Hårteigen, «the grey signpost», as the name suggests, is a landmark for mountain hikers on the western plateau. The piece of mountain is also a monument for the mighty rock layers that once covered the entire plateau.
