Must See/Must go
The Carcans-Hourtin lake is France's biggest natural freshwater lake with over 6.000 ha. The Carcans-Hourtin lake has a 2km-long beach with full amenities at Maubuisson, with a sheltered eastern bank and sandy coves on the western bank. Bordered by the dune and the trees, the lake's preserved environment is a sanctuary for a host of protected heritage species.
The Natural reserve Etang de Cousseau fosters a great variety of natural landscapes. The reserve is located behind the sand barrier beach and the national forest. Follow the 7km-long trail to discover sceneries unaffected by time. You walk through wood-covered dunes looking like rainforests, along humid " barins " ( vast damp areas ) covered by giant ferns, admire the vast marshland which is the summer pasture land of the last " vaches marines " ( a local cattle breed ).
