Domfront
We didn't climb here, although we saw climbers on the crag from the road as we headed out toward La Fosse Arthour.
The crag lies on the north side of the N176 just after you turn west from the D962 70km south of Caen. Locally, about 20km south from Flers, and 40km south of Clecy.
The crag was bolted but we only saw it, (100m or so away), from the roadside. There were 10 or so climbers on the crag and it looked well worth investigating.
There is a campsite at Domfront.
More info as I get it - try the web search engines or cosiroc.
There's a topo available here
