Randonnée géologique - Le karst de La Pierre Saint-Martin

Under our feet, the mountain continues to transform itself... Led by a geologist and supervised by a mountain leader, this outing invites you to explore a spectacular landscape shaped by time and water. Along the way, we'll cross this vast karst plateau carved out of Cretaceous limestone, in search of the geological clues that tell the story of this exceptional territory. Chasms, fissures, lapiaz and shapes sculpted by erosion will gradually reveal the secrets of a landscape in perpetual evolution. We'll see that this story didn't stop millions of years ago... it's still going on today.

350 m ascent. Bring: suitable clothing, sun protection, picnic and water.
