From the Atoll Achensee, follow the cycle and footpath to the lakeshore. At the pier “Seespitz”, you can choose the lakeside promenade on the right and walk to Pertisau. Alternatively, you can walk across the road and take the elevated panoramic path through the forest. Follow the signposts until you reach the valley station of the Karwendel cable car. If you continue walking to the Langlaufstüberl at the end of Pertisau, you have reached the entry to the Karwendel valleys. The hiking trail along the lake is barrier-free. The return is via the same route.
Tip: Alternatively, you can return to the starting point by bus or by ship to the pier “Seepsitz”.
