Göschenen - Lochberglücke - Realp

From the Gasthaus Dammagletscher at the Göscheneralp reservoir, walk over the dam crest to the southern lakeshore. Then hikers follow the path to the junction at point 1927 (from here the route corresponds to a T4 hiking trail with white-blue marking) and ascend towards the pass. On the right side, the crystal cave at Planggenstock can be seen. At the Alpergensee, the path continues uphill to about 2690 m above sea level, then keeping right to the Lochberglücke. 

The return path follows the ascent path through the Realp forest down to the village of Realp with 160 inhabitants or alternatively down to the Albert-Heim Hut. From there, you walk on the hut trail or alternatively over the Schafberg to Tiefenbach at 2106 m above sea level, where you can take the bus to Realp.
