Route report (French scale)

It’s possible climb the route directly from Gorezmettlen (1000 meters dl. from the starting point to the summit). Otherwise you can stay overnight at the Sewen Hut.

From Sewen Hut head to North (on your left-hand side when getting to the hut) following a not very obvious trail rising towards a crag (equipped single pitch’s routes). From the crag turn to left following a long level trail leading to a steep and wide scree-slope. Climb it making a wide semicircle towards left to reaching the bottom of a very steep rocky and scree gully (red marks). Climb it, then traverse to right (red marks) skirting the rocks and reaching a huge block, nearby a red mark with a bolt. (1 hour from the hut, 2,20 hours from the parking).

L1 – From the starting point climb the gully, then its right side, leading to some slabs with good holds. Belay on the right. 4b
L2 – Up a good slab, leading to a little overhang; climb it on its left edge, then a fine wall, steep but with good holds, leading towards right inside a steep corner. Climb it and reach the stance. 4c
L3 - A very pleasant and beautiful climb along the characteristic wide corner, sloping at first, then steeper leads to a good stance a bit on the right of the corner. 4b
L4 – Another good and satisfactory pitch inside the corner. Belay on the left under an obvious overhang. 4b
L5 – From the stance climb straight towards the overhang, then skirt it on the right (crux) and reach the stance.
L6 – Easy rocks leading to the beautiful summit. Summit cairn and summit-book.


Best descent: from the little summit scramble down to reach the first abseil’s anchor, then make four abseils on the route. Another way, more complex, is scrambling down towards East (towards left facing out) along the summit ridge to reach a gully coming down at the bottom.
