Info & Topo from Bleau,info
One of the furthest south locations but well worth a visit.
Small but popular venue just outside the suburbs of Nemours. North facing and shaded so can hold moisture but perfect for a warm day. Beware the Mosquitos in the summer.
Get here before 11am or in the evening to miss the crowds.
In Saint-Pierre lès-Nemours (easily accessible from Larchant by the D16), take the Rue des Hêtres and drive along the dirt track for 300m. The circuits are close to the parking lot.
