Long gravel path, very smooth except for a short, slightly grassy section but relatively dry for most of the year. Really enjoyable on a mountain bike or gravel bike.

This beautiful section of the circuit in the heart of the Grandlieu marshes can only be used by bike in summer (as it is covered in winter).

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.

The church is actually called Saint-Médard. Saint-Médard, the contraction of which gave Saint-Mars.
