Located at the northern end of Lake Paladru, this wetland is fed by the Courbon stream. It is a true extension of the lake, rich in biodiversity and very pleasant.

Here, you enter a sensitive natural area for a 1-kilometer trail marked with four stations to discover the area's remarkable flora and fauna. A pleasant way to connect the two shores of Lake Paladru, between Paladru and Montferrat.
