Walking along the discovery path is the ideal way for everyone to discover how nature has been marked by history.
It provides a remarkable view point over the plain of Valence and also provides the opportunity of discovering the castle ruins, especially the keep.
It offers several stages that allow you to understand the Alpine uprising, the flora and fauna or the rock in the center of Pangea.
This rock sends the hiker some 240 million years back when all the continents were one.
It would still symbolize the center of the original world today.
