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.
