Port d'hiver - Passay - Lac de Grand Lieu

Viewpoint

47.7 km

Make your outing a bit unique by crossing the river "L'Ognon" aboard the Martipontain. A barge that allows you to cross to the other side by pulling on the chain that connects it.
Fun in a group, a little more physical on your own!

Site to come and relax, admire the flora and fauna on the shores of Lake Grand-lieu. Arrangement that respectfully blends into the decor for a lovely moment of reverie and history with the Saint-Rachoux fountain located at the entrance.

Lake path between Bouaye and Saint Aignan de Grand Lieu

Highlight (Segment) • Trail

Shaded walking path, accessible to all, along the marshes of Lake Gd Lieu.
At the end, Coté St Aignan, you absolutely must continue to the equally unmissable site of "Pierre Aigüe" in order to admire the most beautiful view of the Lake and its environment.
