Green gem in the Grimsel area

From the post bus stop Chüenzentennlen above Handegg, the path initially ascends gently between berry bushes and over wet meadows, then somewhat steeper through rocky terrain. There are beautiful views down into the valley of the young Aare and the opposite side valleys. The ascent to Gelmersee does not involve major exertion.
The circular route around the reservoir is laid out as a mountain hiking trail. Along the southern shore, the route initially follows mostly level paths heading east, then a short ascent follows and subsequently a descent again. The lake lies in a valley whose side walls are quite steep. Therefore, the path often runs only as a narrow path over steep rock slabs along the water. In exposed spots, steel cables provide support.
There are opportunities to rest, for example, on the east shore where the Alplibach flows into a flat mountain meadow with scattered rock blocks, as well as near the location Undrists Diechter around the Diechterbach. There is also a junction there from which a mountain trail leads up to the Gelmer hut (ascent 1 h 35).
The Gelmersee circular route continues to the northern end of the dam. Here is located the mountain station of the Gelmerbahn. Recently, the originally power station-operated, extraordinarily steep funicular railway has also been opened to the public. Those to whom such a downhill ride feels too spectacular and breathtaking can cross the dam and return on foot to Chüenzentennlen.
