Le Viaduc des Fauvettes
The Viaduc des Fauvettes is a magnificent section of track in the Vallée de Chevreuse. A demanding vertical climb awaits you all year round in this green haven accessible by public transport. Our ethical topo was produced in collaboration with Jean-Yves Derouck of the COSIROC association. Profits from the sale of our guidebooks are donated to the association to help finance the construction of new routes and the upkeep of the site.
