A gravel path through the forest, without potholes, suitable for a touring bike with thicker tires. The path is partially shaded and there are many places to picnic along the path under the trees.

To be practiced outside the wet season so as not to end up underwater. Superb at daybreak.

Among the hedges and the oaks, you may be able to observe nesting birds of prey, rare in the Pays de la Loire. This small forest is pleasant to walk through - the trail is open from May to October.
