Crêt Pourri

Crêt Pourri is a mountain summit in the Jura Massif that overlooks the town of Saint-Claude and the surrounding valleys. From this vantage point, hikers can see across the Flumen Valley and toward Mount Bayard.

The summit formed over millions of years through geological processes that shaped the entire Jura Massif. Rock formations here preserve evidence of ancient environmental changes in the region.

The hiking trails around Crêt Pourri incorporate several heritage elements including the Vaucluse Chapel and the Devil's Bridge.

Wear sturdy hiking boots and bring water, as the trail climbs steadily through wooded terrain with few spots to rest. The best time to visit is late spring through early autumn when paths are dry and weather is more stable.

The rocks contain oolitic and marly limestone that preserves signs of a tropical lagoon environment that existed here millions of years ago. This geological feature makes the summit of interest to anyone curious about Earth's ancient past.
