  La Pierreuse, a landscape petrified by time

An itinerary in the natural reserve of the Pierreuse, which invites the reader or the walker to a trip through the memory of Earth. It brings us through millions of years of the history of our planet that she keeps preciously engraved in the rocks. Before being a mountain, the Pierreuse was a sea, with its beaches and tropical islands.
