Martin and I were down in Les Ecrins yesterday. We had a great day out near La Berarde climbing the Voie Boell on the Aiguille Dibona. This route is given AD in the British guidebook, but D- in the Jean Michel Cambon guidebook which can be bought locally. It is useful to have both guidebooks as the route finding is quite complex.
We descended via the North Ridge which gives an excellent PD in it’s own right, making the Dibona a summit for Mountaineers of all abilities.
The Refuge du Soreiller is located right at the bottom of the peak and is very friendly. There are a large number of routes and peaks that can be done from this hut making it a great base for a few days.
