Walk around the ornithological reserve of Teich

The walk starts from the parking lot of the bird sanctuary of Le Teich and then goes along the sanctuary. Why not visit directly the ornithological reserve? Because we are not passionate about birds and the entrance fee for the ornithological reserve at 9,60 euros seems a bit high. So we take a path that goes along the reserve. The problem: there is not really a way back, we have to go back on our steps. So we decided to go towards the Arcachon basin and to come back afterwards. You need one hour of walking without hurrying to reach the basin of Arcachon. The walk is easy, everything is flat, be careful for cyclists, the path is narrow.
