Discover the fabulous voyage of the mysterious boulder called "Pierre à Martin" and be amazed by the view on the Leman lake.
The Hill of The Madonna overlooks the field where you find the Pierre à Martin. The vines, like the mysterious erratic block, are the legacy of a glacial epoch:
with its advances, retreats and final melting, this giant transformed the landscape and shaped its soils… What more is needed to fuel the legends !
