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 tourist attraction in this area is Lake Paladru, which stretches from the village of the same name in the north to Charavines in the south. If you walk around the lake from a distance rather than on the paths directly along the shore, the hills offer some very beautiful views of the landscape. But not only that: on the outskirts of Bilieu – on the eastern shore of the lake – we pass a small sacred monument: a simple wayside cross made of two massive wooden beams (without a body or INRI inscription), which already shows the wear and tear of wind and weather.

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.

A very popular lake to visit during the summer months when the lake is quite refreshing. Every year, there is a time trial around the lake.

A completely crazy climb, you have to be crazy to try it! Absurd percentages! But what pride to reach the top... plus, the climb is part of the official route of the 2025 French Championship!

The traffic-free gravel trails around Lac de Paladru offer a mix of surfaces. You'll encounter segments of hard coating, gravel, and paths through undergrowth, such as in the Bois d'Amour.
