The route starts from Høyanger Bus Terminal. Follow the walkway up past Hydro and exit right by the bus shelter on the hilltop. Here you follow the stairs 1268 steps straight up alongside the penstock. From approx. step 600, there is a fantastic view of Høyanger. The tunnel at approx. step 1000 is also an amusing experience. Continuing, follow the penstock a little farther on the left until you reach a bridge and cross it. From there, Sommerstien is marked until you reach the Grimsosen Dam. It may be a little wet some places along the trail, and certain places may also be steep
and slippery. When you get out of the forest, there are several nice places where you can sit down.
From the dam, follow a gravel road and Fjellvegen mountain road down again to Høyanger. You can also go across the dam and continue up to Toppenhytta cabin (approx. 1.5 hours extra).
