From Sant. Moritz

From the departure station of the Signalbahn cable car 1774m, large paid parking lot, follow the ski runs past the forest belt of God Laret and reach the huts Alpina 1903m, then continue up to the upper station of the Signalbahn cable car 2130m, continuing on paths through the middle of the alpine pastures of Alp Giop, now with a traverse to the north reach the upper station of the little train of Corviglia 2486m. Climb near the 2526m contour and with a traverse to the west on a gentle ascent, enter Valletta Schallatain, follow this little valley in places along the ski runs and reach Fuorcla Schallatain 2873m.

From Fuorcla Schallatain 2873m in a north direction reach F.Grischa 2960m approx., now climb the loose debris couloir to the left of the summit up to its top and on easy rock steps, now more solid, leaning slightly on the north side, the summit is reached shortly.

Descent by the ascent route, or it is possible to descend along the northeast ridge until finding a steep slope of debris on the right south that allows one to descend to the basin below to the southeast of the summit down to about 2980m and then return to F.Grischa, or descend toward the chairlift of Pizzin 2688m and return to the ascent route after a traverse toward Lej Alv 2533m, where an ample water storage basin is still under construction and will be included in this basin.

When in the basin to the southeast of the summit it is possible to climb Piz Corviglia 3060m, however one must descend to about 2840m and then on ganda in a north direction first traversing in a gentle descent then climb to Fuorcla Persa 2925m and by its south slope on some easy rock passages the summit on the right is reached, descent along the ascent route, or descend over easy but steep terrain with loose stones or on snow on its north slope into the Chüdera basin, from where, besides descending to the valley from this basin, it is possible once at about 2900m to traverse north over debris or snow to the base of the steep couloir of loose rocks to the left of Piz Glüna, climb this couloir without great difficulty for about 80m of elevation gain (pay attention to loose stones). Once the pass is reached, climb now on more solid rock with a few short passages of 1/2° and along the west ridge climb to the summit tending to stay slightly on the left side of the ridge crest.

Descent by the ascent route.
