Mountain and winter sports Essonne

The viaduct of Fauvettes is located in a green and wild valley between forest of chestnut trees and meadows. Built at the beginning of the 20th century, it is a railway viaduct disused since the 1939-1945 war on which a simple hiking trail now passes. The building has 11 pillars of millstone about forty meters high, which makes it the highest site in the Ile-de-France. Closed since 1997, it was reopened in 2004 for climbing and caving. A trail is organized there every year in October.
