In reply to RobbieT:
In that case no, I've only skinned up from the tunnel. However, the summer path up the Montagne de la Côte zig zags up very steep terrain in the trees and I'd imagine it'd be well banked out with snow which it's likely to hold for a long time given its aspect. Having tried on numerous occasions to skin up snowed-up summer paths in forests around Vallorcine I'd say it'd likely be combat skinning! Give it a go and let us know...
