As you walk through the serene Parc de Lormoy, you will discover a fascinating collection of wooden sculptures scattered throughout the park. These unique works of art, made from fallen trees, are a testament to the creativity and skill of local artisans. As you walk along the winding paths, you will be captivated by the intricate details and imaginative forms of each sculpture. Take time to appreciate the beauty of nature and the art that transforms ordinary wood into extraordinary masterpieces.

This site consists of 86 hectares of ponds, wet woodlands and peat meadows. Take the time to explore around the ponds and appreciate the rich biodiversity of the marsh.

The Carouge basin is the point of convergence of the Orge, Blutin, Salmouille and Boële. The basin was dug in the 1970s to extract materials for road construction, and also to manage the floods of the Orge. Here you can see many species of birds, such as seagulls, cormorants and ringed plovers depending on the season. The path along the basin is safe and flat.

The bridge over the Orge, near the Bassin du Breuil in Épinay-sur-Orge, is a charming passage that offers a peaceful view of the river and its green banks. Surrounded by trees and paths, this bridge is an ideal place for a contemplative break. The murmur of the water and the serenity of the landscape invite you to relax.
