L'Odyssée des Fossiles

who invites you to board an extraordinary vessel: the Nautilus. Destination? The high alpine peaks at 2,500 metres, for an expedition where science meets legend.

Whether you're a curious hiker or on a family outing, you’ll be guided by a seasoned mountain professional who leads you through this fascinating world. He takes you along the hidden trails of the Désert de Platé — a lunar-like plateau sculpted over time by glaciers and flowing water. Beneath your feet, the ground seems to whisper the story of an ancient ocean floor. Embedded shells, fossilized textures, and etched limestone slabs unfold like open-air archives from millions of years ago.

And all around, the magic continues. The horizon reveals the mighty Mont Blanc, towering in the distance, while life quietly reclaims its place in this mineral world. Playful marmots dart between rocks, butterflies dance on the breeze, and raptors soar overhead… Life reveals itself when you least expect it. Thanks to your guide’s insights, young and old alike uncover the hidden wonders of this timeless landscape — and learn how to protect it.

A true alpine adventure, led with passion and expertise.
