Apart from the riding in the eastern regions of France, are there many other more regional areas in the rest of France where people can get good MTB riding?
doh - hadn't thought of looking at trailforks....Massif Central, puy dome area, Pyrenees, Brittany, vosges mountains
Check out Trailforks
brittany ?
Yup .. not really known for it's mountains But there are a few places with some reasonable "hills" where there's some ok downhills (2km max...not vertical ) and you can get in some reasonable elevation changes in not too long a distance. Round lac de Guerledan there's a few hundred k's of trails.
None of the trails seem to be on trialforks .. so strava sadly :

Wikiloc shows 5 routes for your area, @Zimmerframe - perhaps you can say whether they are any good?
All 5 your could do on a road bike sadly ..
