There, the meadows are dotted with granite balls called "oxen". Large granite blocks with rounded shapes outcrop there. They result from the weathering of the granite into balls under the action of infiltration water.

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.

While specific rules for each natural monument may vary, many outdoor areas in the La Manche region are dog-friendly, especially on trails and in natural parks, provided dogs are kept on a leash. It's always best to check local signage or specific park regulations upon arrival to ensure a pleasant visit for everyone.
The Waterfalls in Mortain are indeed a significant natural feature in the heart of La Manche's bocage countryside, known as the largest waterfalls in western France.

The best time to visit depends on your preferred activities. Spring and autumn offer pleasant temperatures for hiking and cycling, with beautiful foliage changes.
