From La Roche-sur-Yon, the greenway follows a former railway line that winds through the countryside around La Roche-sur-Yon and passes through the towns of La Génétouze, Aizenay, and Coex. Beyond this point, this lovely route can even lead to the ocean. To do so, you must use a shared path for 6 km, then rejoin the St. Hilaire de Riez greenway.
