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!

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.

Window over Lake Grand-Lieu

Highlight • Other

The lake is a natural site and an ornithological reserve and its access is very limited to the public. There are not so many views on this one. You can find them on the lacdegrandlieu.com website
