Located at the northern end of Lake Paladru, this wetland is fed by the Courbon stream. It is a true extension of the lake, rich in biodiversity and very pleasant.

Here, you enter a sensitive natural area for a 1-kilometer trail marked with four stations to discover the area's remarkable flora and fauna. A pleasant way to connect the two shores of Lake Paladru, between Paladru and Montferrat.

A beautiful bridge that crosses the Rhône and demarcates a departmental boundary. It even offers a view of a castle!

The small rest area created here, with its very unusual design, invites passersby not to roll by carelessly: Behind the backrest of the bench rises a remarkable piece of craftsmanship: on one side, a flower stem bearing an unfolded blossom; and from the other, a bee flies towards it. An original idea, and rightly documented here several times with photos.

Here we encounter three stone cubes stacked on top of each other, each smaller than the one below it. The gray cubes each have a white field in the center of their sides, with a cross carved into it, painted blue and standing out against the gray/white background. This construction forms the basis for the present small sacred monument: above it rises a radiant gold figure of the Madonna. From this prominent position, the Virgin Mary – venerated in France almost always under the title "Notre-Dame" ("Our Lady") – gazes far into the country, and has done so for more than 120 years. @Rainer N. has already explained the date and reason for its construction in his short post.
