Classic limestone slab climbing with amazing runnels, (cannelures.)


2 possibilities: From Glières or Thuy, 1h in each case.

From the N, Glières

Take the road from Thorens to the Glières plateau. Once the road starts go down again take a right turn and then a second right turn after a few 100 metres, (Ablon). Park at the start of this road as vehicle access is restricted. Walk S, direction Thônes, on a shaded track. A little before reaching the Rosiere Chalets, take a path to the right to reach a scree slope leading up to the foot of the cliff.

From the S, Thuy

From Annecy follow the Thones road and leave it for Thuy, (a liitle before Thones.) Take the road through Sapey and about 700m beyond, take the track for 500m to Nant-Debout. Park here, (not many options.) Walk along the GR 96 and the little valley to the Rosière Chalets. After the chalets take the path on the left which lead up to some scree coming down from the foot of the cliff.

The route starts 40m to the left of the top of the scree cone. The name is painted on the rock.


L1 5c A bit strenuous (or A0) then 5b, steep but good holds.
L2 4b/4c Short wall then a nice slab with pockets.
L3 4b/4c A slab then delicate climbing up a runnel, 5b
L4 5b A very nice slab with a runnel a with a difficult move at the end.
L5 4c/5a Beautiful runnels, classic climbing for the grade.


Abseil down the route.


Very well bolted
