Toit d'Orsay
The boulders are situated on a private plot, but despite extensive research the owner is still unknown. So, for the moment, your discretion is very much appreciated if you pay the area a visit! It is located in Orsay (Le Guichet) near Paris, about 35 minutes North of Fontainebleau. On this page you find an access map of the area, please park at the designated parking lot drawn on the map, in order to be as discrete as possible! The area, which has been discovered in 2000 by Fabien Marchand, has only a few climbable boulders.
Update (May 2026): the big flake in Quoi de Neuf (acte 1) has collapsed in 2025 and several very hard problems have become obsolete. Fortunately, part of the roof has been reinforced with Sika in Spring 2026 and new versions have been created.
🚊 The access is easy by suburban train (RER B, station Le Guichet).
🚌 It is also possible to use the bus lines 91-6 and 9.
