Signal de Saint-Pierre

Signal de Saint-Pierre is a summit in the Vaucluse Mountains with an elevation of 1,256 m (4,124 ft), the highest point in the Luberon Regional Nature Park. The mountain consists of limestone formations and offers far-reaching views from the top across the landscape below with its plains and distant ranges.

The mountain formed during the Mesozoic era through geological processes that created massive limestone deposits. Over time, water erosion shaped underground caverns and channels, forming the karst landscape system that exists there today.

The slopes have been shaped by lavender growers for centuries, whose traditional farming methods still define the landscape today. Visitors walking upward encounter small lavender fields and old dry stone terraces that speak to this long agricultural tradition.

The ascent follows marked hiking trails accessible from road D40, with parking available near the base of the mountain. Visitors should wear sturdy footwear and bring adequate water and sun protection depending on the season.

Lavender growers in this region produce a significant share of French fine lavender oil, thanks to the elevation and local climate that create particularly aromatic varieties. The area is recognized by perfume makers and distilling specialists worldwide.
