Tips from the Community

Eric Mn
August 4, 2025, Moulin de Rambourg sur l'Yon

The Rambourg mill, located in Nesmy near La Roche-sur-Yon, is a rare early 20th-century watermill still equipped with its original mechanisms. It ceased its milling activity in 1981 and has since been restored and opened to the public for guided tours during the summer, from July 1 to August 31, every day except Saturday. The interior of the mill can only be seen during these guided tours, allowing visitors to understand the traditional workings of the mill. The site also offers a bucolic setting conducive to relaxation, with a ford, picnic area, and walks along the banks of the Yon. The mill participates in Heritage Days with specific activities.

In the south of La Roche-sur-Yon, the Yon takes on a green air that invites calm. Here, a charming path allows you to stay close to the water. Be careful, however, to have a bike with suitable tires.
