Scramble up the grey blocky rocks to the base of the crack. Clip the cemented piton anchor. Follow the crack, interrupted by small overhangs, up to the belay (3 pitons). (35 m, V)
Diagonally to the left, then up to the dihedral/gully that you follow until an overhang forces you to move slightly to the right. Follow the short dihedral that ends on a ledge with the belay (2 bolts, chain & ring). (30m, IV-)
Reach the dihedral to the left of the belay and follow it. At its end, a gully leads to a ledge with a small cave. Move a little to the right to the belay (2 bolts). (25m, IV+)
Climb directly above the cave, following the crack on the left. (2 pitons). (20m, V)
Follow the dihedral gully up to the saddle. Along the ridgeline you reach the top of Torre Stabeler with the anchor (cemented piton). (40m, IV)
overcome the overhang above the belay, then continue on simpler rocks in a slight oblique to the right up to the belay (glue in bolts x2 and ring). (25m, IV, 1 piton, 1 bolt)
Diagonal to the right in the direction of a black corner that you follow for a few meters. Traverse the slab to the left, bypassing a yellow overhang and climb up to the comfortable belay at the base of the overhanging yellow wall (glue in bolts x2 and ring OR old belay on 3 pitons). (25m, IV+)
Climb the dihedral above the belay until below the overhang; traverse for about 2 meters to the right and pass it. Above this, follow some easier blocks to the anchor (glue-in bolts x2 + ring). (30m, V+/IV A0, 12 pitons, some dodgy).
Climb the slab (unprotected) aiming for the obvious left slanting chimney at the end, which goes to the belay (2 bolts + chain). (35m, V+, 8 pitons, 1 intermediate anchor)
