Breaking Down the Itinerary

Starting Point & Introduction: The tour kicks off in front of the Sisteron Tourist Office, where you’ll meet your guide. They’ll give a quick overview of the UNESCO Haute-Provence Geopark and explain the fascinating geological history of the region. Knowing a bit about the land’s tormented past helps you appreciate the rugged beauty around you.

Climb to the Trou de l’Argent: Expect a roughly 1.5-hour ascent along a well-defined trail leading up to the limestone massif of La Baume. The climb is steady and at a relaxed pace, accommodating those in good shape but not suitable for anyone with mobility issues. The reward? Views start opening up, and the sense of anticipation builds.

The Cave Passage: Reaching the foot of the Trou de l’Argent involves climbing a metal ladder into a narrow entrance, leading you into a small underground world. The cave itself offers a few natural windows to the outside—ideal for photos and a moment of awe. The underground section isn’t overly long but adds a definite adventure factor, perfect for those looking for a bit of underground exploration.

Ridge Walk & Panoramic Views: After exiting the cave, you’ll hike along the ridge of La Baume, where panoramic vistas of the Alps and the Provencal countryside unfold before you. Standing there, feeling the vertigo but knowing you’re safe, many guests find this moment humbling and exhilarating. The guide’s insights about the local geology and environment enrich this part of the journey.

Descending Through Forests: After soaking in the views, you’ll descend through lush forests on the northern slopes of Montagne de la Baume, which offers a cooler, shaded contrast to the climb. This calmer, wooded section helps balance out the physical effort and lets you reflect on what you’ve experienced.

Summit Aperitif: The tour concludes with a relaxed aperitif at the summit, giving everyone a chance to unwind and share impressions. It’s a lovely way to cap off a full day of adventure.
