Departure from Orsay (Essonne)
Whilst awaiting the opening of Metro Line 18, those working on the Saclay plateau in the Corbeville area who use the RER B can choose between two long, steep flights of stairs or a steep path, on either side of the former La Troche quarry. This gave rise to the idea for this circular route – short but challenging – which can be completed as many times as one wishes and thus provides excellent training ground before tackling climbs of varying lengths during the summer.

Departure from Bures-sur-Yvette (Essonne)
A loop in the Chevreuse Valley, with magnificent landscapes, in a wooded and rural setting close to Paris. The first part is a walk through the woods on the plateau overlooking the Yvette Valley. The return journey, parallel to the outward route, is mainly on flat ground. Most of the walk is well shaded and flat, but there are also some fairly steep ascents and descents. The area is very popular with walkers and mountain bikers, but it is well worth a visit.
