The Zig et Zag trail is dotted with 8 interactive panels where you can learn all about the life of the bat colonies in the commune of Cessy-les-Bois.
It's well worth making the diversions to this village nestling in the Talvanne valley. The walk starts from the church car park.
Zig and Zag are bats known as the Great Rhinolophus and the Stilt-Eared Bat.
In autumn, the bats gather to hibernate, and this is a unique opportunity to see them all in one place.
To find out more about this species, you can pick up a booklet to accompany the trail at the Bourgogne Coeur de Loire Tourist Office, or at the visitor centres in Cosne-Cours-sur-Loire and Pouilly-sur-Loire.
