Fauvettes Viaduct

Highlight • Bridge

Magnificent viewpoint over the valley surrounded by greenery, accessible by "gravel" paths (roots and stones) through the wood or by "hiking / mountain biking" trails in the valley (it will however be necessary to ascend the elevation on foot in this case).
Built in 1913 for the "Paris-Chartres" line, bombed in 1944, unused, closed, the viaduct was recently renovated for leisure. We see caving groups training there, as well as climbers who practice climbing on the pillars.

The Chemin du Bras Mort cycle path in Bures-sur-Yvette offers a serene and picturesque ride through the natural beauty of the Chevreuse Valley. Following the meanders of the Yvette, this path takes you through lush greenery where you can observe the fauna and flora along the banks.
