It's a beautiful starting and finishing point.

Viltain Farm then the singletrack further west is a little paradise. Landslide (04/2025) on the way back

Near Maincourt-sur-Yvette, this wood has beautiful rock formations climbing up the first slopes of the Chevreuse valley, just a few meters from the river.

This waterfall is artificial, the mill is located on the left of the photo.

In the morning, the rocks show blue reflections.

It is a beautiful place that is quite cool even in the heat because it runs along the Yvette and several ponds, but it concentrates a lot of people on Sundays on a fairly narrow path. In high season, prefer Saturday for this course

The “Petit Launay” oak (the aulnoye), remarkable for its size and the distribution of its branches, seems to date back to the 15th century. The organizers of the Universal Exhibition of 1900 in Paris wanted to transport it to the capital, which attests to the interest that this Tree already presented. Mr Grisier, mayor of Bures and owner of “Petit Launay” fortunately declined this offer. This estate, a former stronghold from the 14th century, has been better known, since 1810, under the name of "The Virgin". A statuette is still visible on the surrounding wall of the property. It is crossed by the Vaularon, a tributary of the Yvette, hence the humidity conducive to the growth of alders. This tree has been classified in the list of “venerable trees in France”.
