St Germaine le Vasson
Didn't visit this crag on our recce but it's down for a visit next time. This crag is about 5km north of Potigny (la Breche au Diable) and 15km south of Caen on the N158 - turn off west on the D239 at St. Grainville-Langannerie for about 2km. It appears that there are 10 or so routes in the 6 - 7 grades. I get the impression that this crag is not bolted and not particularly high - possibly only 5 metres or so.
The site here has some information.
