Spanning a vast area of limestone mountains and valleys, this protected reserve is one of the most important geological sites in Europe.

Covering nearly 1,900 square kilometers, it preserves landscapes shaped over hundreds of millions of years, with visible traces of ancient seas, tropical environments, and shifting continents.

The Réserve Géologique de Haute-Provence is especially known for its rich fossil deposits, including marine fossils and prehistoric remains embedded in the rock. Several marked sites and trails allow you to explore these formations up close.

Beyond the scientific interest, the reserve also offers striking scenery, with cliffs, valleys, and open landscapes that feel wild and largely untouched.

It’s a place where you can combine walking, learning, and exploration, whether you’re interested in geology or just want to experience a more rugged side of Provence.

👉 Local Tip: Visit one of the designated interpretation sites rather than wandering randomly. You’ll understand what you’re seeing much better.
