This small sector, at 2km from the railway station of Etrechy (RER C) has been rebrushed and repainted by Pascal Etienne in 2011, who has added 20 orange problems.
Access: park the car in front of the gymnasium of Le Quartier du Roussay. Follow la rue des frères Kennedy for 150m and then a path between two houses parallel to the road. 150m further, another path leads to the sector.
