CLIMBING ON BOULDERS IN SAINT JACQUES
You can find them at the end of the asphalted road, at the entry of the inter-farm road to Nana.
The interesting rocks are three.
The triangular rock is outfitted above a cement stake. You can easily climb it from the mountain side and there are numerous interesting slab passages.
The highest big rock is evident and offers 3 free routes, also usable as aid routes. The difficulties from the right side are: 5+, 6b+, 7b.
