Today, only one quarry still extracts the “Bleu de Vire” granite. It is used to produce cobblestones for pedestrian areas in cities, tombstones for funerary monuments and for high technology (space conquest, robotics). Hikers will encounter pierced granite stones along this route.

the ornithological reserve of 4 hectares is of remarkable interest thanks to many species nesting in the wetlands: great crested grebe, little grebe, mallard duck, coot, lesser plover or even the reed bunting. Three observatories have been installed on the edge of the lake to better admire these birds without disturbing them.
