Swimming banned in 76 Pyrenees National Park lakes due to heatwave and fragile ecosystems

The Pyrenees National Park has implemented a strict ban on swimming and all aquatic activities in 76 of its lakes, effective since June 2, 2026. This measure, established by two prefectural orders, targets lakes, ponds, and streams situated above 1,000 meters in altitude within the park's core zone. The protected area spans over 45,700 hectares across the Béarn and Bigorre regions.

The park cites several reasons for these restrictions, primarily driven by a significant increase in visitor numbers. Concerns include potential chemical and organic pollution from soaps, sunscreens, and insect repellents. Additionally, the park aims to protect its delicate biodiversity, reduce noise and visual pollution, and ensure public safety in a naturally unpredictable environment. Activities like "aquarando" and "ruisseling" (stream walking) are also prohibited in watercourses, with only fishing, canyoning, and kayaking permitted under specific conditions.

This decision follows a similar ban implemented last summer in the lakes of the Néouvielle Nature Reserve due to over-tourism. While these high-altitude water bodies are now off-limits for swimming, the park is relying on public awareness campaigns through social media and on-site outreach. However, those who violate the ban face a fixed fine of 135 euros. Meanwhile, developed water bodies and thermal leisure centers in the valleys remain open to the public.
