GEOLOGICAL HISTORIES
A landmark site of the Normandie-Maine Park, the Monts & Marches site of Saint-Léonard-des-Bois evokes 600 million years of history that formed the rocks and landscapes of the territory. At the end of this journey, imagine at the bottom of an ocean, beneath the burning clouds spitting by volcanoes, in a shallow sea, under a tropical climate in the time of the dinosaurs. You could have been here with mammoths during cold periods during which the piercing pierces are still visible today.
From the church of Saint-Léonard-des-Bois, you take this marked trail that takes you to the heights of the Sarthe by revealing the astonishingly mountain character of the Mancelles Alps.
