Park in the Lac de Saint-André car park.
The path around the lake is not only marked, but also partly on stilts, so it's impossible to get lost!
(S/E) Follow the trail from the restaurant towards the playgrounds and the fishing port.
(1) Walk along the lake on the wooden pontoons and continue the tour in an anti-clockwise direction.
(2) Return along the cycle path and head back to the car park (S/E).
