Bagnoles de L'Orne.
Unfortunately, our recce didn't allow us enough time to visit this crag.
The topo for La Fosse Arthour lists crags - les Rochers d' Andaines. The 'Foret des Andaines' has Bagnoles de l'Orne almost at its centre. A topo is available - part of a trio of guides for 'Le Gres Armoricain', the other two topos being for Mortain and La Fosse Arthour all coming under the Parc Naturel Regional Normandie Maine. These guides should be available from here - see below.
The topo suggests 120 routes, graded from 3 to 6 and clearly bolted.
The outcrop appears to be in a wooded area to the west of the town but another source reports there is a crag in the centre of the town, near the Hydro.
The cosiroc site may well be worth a look.....More as we get further info.
