The rules on fishing in the mountains are the same as they are in the rest of France. You must have a fishing permit. This can be a one-day, one-week or one-year permit (Adult or Inter-Federation, Women’s Taster, Child/Teenager, or Under 12s Taster).
Anglers can purchase fishing permits all year round in tourist offices as well as specialized shops like France Rurale in Moutiers or online cartedepeche.fr
