Mont d'Olivet
One of the more unknown areas around. This is located in the south in Nemours on top of a hill. Not extremely stroller friendly approach, but if one makes it, it's a wonderful spot for the entire family.
The area features a few harder problems, some of these harder ones are quite high, but the general theme is easier circuit problems. You can find a blue D circuit 1-27 long here and an orange AD 1-28 circuit. Both are excellent by stone quality and good options as ones "first" circuit for someone. Both circuits features mainly problems with very good landings.
Excellent area also for days when the northern part of the forest is hit by rain and south stays clear.
The area is located on top of the hill with mostly small trees giving shade, so it dries quickly as well, but might be a bit hot for summer months.
The reception up in the area is for most part very good.
Good combination with Les Mammouths if one seeks for some harder problems as well.
