Blue, you didn't expected to be right : I have grown up just near this mount ... And spent a lot of time in this woods, building "cabanes" in complete freedom !!!
It is located in the center of France (departement 43) and its name is "mont Miaune" just near the river LOIRE , and a 1063 m high mount... GPS : 45°13'18.81"N , 3°58'10.81"E...
