Delta de la Leyre

Maison de la Nature du Bassin d'Arcachon, 33470 Le Teich

The delta, where the Leyre flows into the Arcachon Basin, comprises a variety of areas where stable sections – consisting of salt marshes, embanked areas, reed beds, grazed meadows – coexist with areas subject to tidal dynamics, sandy banks and mudflats. The river’s fresh water and the ocean’s salt water meet here, creating ideal conditions for specific species to thrive. Situated on one of Europe’s most important migration routes, it is truly a haven for birds. A 9 km trail allows visitors to explore the gallery forest as it runs alongside the Leyre and the wetland plains surrounded by marshes further downstream.
