To the Schwarzbergchopf (2871m)

At the Mattmark Stausee there is a very nice little peak nearby where you'll get a tremendous view over the Allalin glacier. From the lake itself you'll only see a very small glimpse of the glacier so it's sure worth a visit!
Hike starts at the lake where you follow the right side of the lake and take the first path to the right where you follow a small road up to a small cabine. From there it's a small and sometimes steep path to the summit of the Schwarsbergchopf. Alpinists can go along this route to the Brittanniahütte, the path is well indicated too but requires more equipment.
The return is along the same path.
