France tightens rules on overnight stays in high-altitude Mont-Blanc nature reserve

The prefecture of Haute-Savoie has implemented stricter regulations for overnight stays, known as bivouacking, within the Contamines-Montjoie nature reserve, France's highest reserve located in the Mont-Blanc massif. These new rules, in effect until September 15, come in response to a significant rise in visitor numbers and uncontrolled bivouacking practices.

From June 15 to September 15, bivouacking is forbidden in areas below 2,500 meters and in sensitive zones crucial for wildlife and natural habitats. Overnight stays are now tolerated only between 7 p.m. and 9 a.m. in two designated areas, which can accommodate a total of 90 tents. A recreational area is also available, according to the reserve's manager, Asters. This reserve typically attracts around 200,000 visitors during the summer.

The prefecture noted a "significant increase" in visitors, leading to "numerous infractions" related to bivouacking. The municipality of Contamines-Montjoie highlighted issues such as noise pollution, waste and wild toileting, and the degradation of fragile natural habitats. They also pointed out increasing conflicts between visitors and pastoral activities within the reserve.

This tightening of rules reflects a broader challenge faced by mountain regions: balancing public access with the protection of delicate ecosystems. Other areas, like the Écrins National Park, are also examining bivouacking regulations, with one park noting a doubling of overnight stays in four years, sometimes reaching up to 215 tents per night in certain locations.
