Boissy Vallée de l'Église (Hunting area)
No climbing during hunting season: from mid-September until March.
Sector behind the football field. From the cemetery, cross the football field and continue on the right up the slope. The first boulder is near the top, in a pit exposed to the North, and with the particularity of having pebble inclusions (this is also the origin of the name "Boissy aux Cailles").
