Easy. Recommended for families.
The route starts at Bruflat and goes to Klevgårdsbygda. Continue southwards along road 251 to the Lunde bridge. From the Lunde bridge you cycle on a gravel road along the western bank of the river Etna. The road narrows after a while and ends up as a path that takes you to Etna Camping.
There are some small ascents in Klevgårdsbygda, but the rest of the route is easy.
