Chastillon

Chastillon is a rocky summit rising above Trigance, a small village at the heart of the Verdon Regional Natural Park in southeastern France. Reaching close to 1,199 metres, the peak has long served as a natural lookout over the Jabron valley and the surrounding Provençal hills.

What makes Chastillon worth the climb?

The summit holds the remains of an oppidum, a fortified pre-Roman settlement built by the Celto-Ligurian peoples who once inhabited this part of Provence. Its builders took full advantage of the terrain, placing the stronghold on a steep escarpment backed by cliffs that made the position naturally defensible. Archaeologists have traced similar Celto-Ligurian traces — huts, small villages, defensive enclosures and connecting paths — across five sites around Trigance, and Chastillon is the most visible and accessible of them.

How do you get there?

The hike typically starts right from the village of Trigance, since the peak rises directly above it. The path crosses dry, partly wooded, partly bare slopes typical of the Verdon landscape, with loose stone underfoot in places — sturdy footwear is a good idea. The climb is steady rather than technical, and manageable for anyone with an average level of fitness, though the final approach is steep enough to feel like a proper effort.

What will you see once you're up there?

From the top, the view opens onto a wide plain and the ring of hills surrounding Trigance, alternating between forest cover and bare rock depending on the season and exposure. It's one of the rare spots where you can take in the rooftops of the medieval village, the Château de Trigance perched on its own rocky spur below, and a broad sweep of Provençal countryside stretching toward the wider Verdon massif — all without moving from one viewpoint. The oppidum ruins themselves are modest, but standing among them makes it easy to picture defensive life on this ridge long before the Romans ever arrived.

When should you visit?

Spring and early autumn bring the mildest temperatures and the clearest visibility, making them the best windows for the climb. In summer, the exposed upper sections heat up quickly, so an early morning start is worth planning for. Winter brings wind but also solitude — a welcome contrast for anyone visiting after the Gorges du Verdon's busier summer crowds have gone.

Frequently asked questions

Is there a marked trail to the top of Chastillon? Yes — the route begins in the village of Trigance and follows terrain typical of the Verdon hills. Checking a map or asking at the local tourist office before setting off is a sensible precaution.

Is Chastillon the same place as the Château de Trigance? No. Chastillon is the hill topped by the remains of a prehistoric oppidum, while the Château de Trigance is a separate medieval castle, now a hotel, standing on its own rocky outcrop in the village itself.

How long does the hike take? Times vary with fitness and pace, but a round trip usually takes a few hours — it's worth setting aside half a day to allow for rest stops and time to take in the views.

Is the climb suitable for children? The steep, stony sections make it better suited to older children already used to hill walking rather than very young kids.
