Réserve naturelle nationale du Mas Larrieu

The Réserve naturelle nationale du Mas Larrieu is a protected coastal area where the Tech River flows into the Mediterranean Sea. The landscape features sand dunes, wetlands, reed beds, and marshes that create distinct habitats for wildlife.

The French government established this area as a national nature reserve in 1984 to protect its unique river-to-sea transition zone. This decision preserved a critical ecosystem that might otherwise have been developed or damaged.

This area serves as a vital stopover for migratory birds seeking shelter and food. Visitors can observe numerous bird species passing through during migration seasons and understand why this habitat matters for their survival.

The reserve has marked paths and information boards that guide visitors through different areas. Camping, collecting items, and bringing pets are not permitted to protect the natural environment.

The reserve protects one of the last natural river mouths along the Roussillon coast, where fresh and salt water meet in an undisturbed state. This rare mixing zone creates conditions found nowhere else in the surrounding region.
