The Moulin Papon Lake dam, via the large Rivoli Park

A route to discover the large Rivoli Urban Park (5), in the shade of the trees, in a preserved biodiversity, and the Moulin Papon Lake dam (10). This lake is used to supply drinking water to the town of La Roche-sur-Yon. The water treatment plant can be seen from the dam. Seagulls and cormorants can be seen on the lake, and from the shore it is not uncommon to spot kingfishers, swallows and swifts in flight. In summer, leisure facilities are available for young and old alike.

Hello
Starting from the Moulin Papon dam, you can take the Vallée Verste route, which winds along the Yon towards La Lardière. A pleasant walk in the heart of the town.

Enjoy your visit!

Thank you for this positive feedback. Many residents in the area are unaware of the possibilities for discovery around La Roche-sur-Yon. This short walk is pleasant without being too long.
