Ocher is a natural clay pigment colored by iron oxide, which was mined in this quarry until the late 1920s.
The intense colors of the site range from pale yellow to deep purple depending on the iron oxide content.
The trails pass through 'The Giants' Causeway' and other eroded formations shaped by wind and rainwater.
The ocher from these quarries was historically used for paints, textiles, and building dyes across Europe.
The site features a micro-environment where acidic, iron-rich soil supports specific plant species not found in surrounding areas.
Strict conservation measures prevent visitors from leaving the marked trails to protect the fragile vertical cliff faces.
The red pigment is a byproduct of weathering in a warm, humid climate that occurred millions of years ago.
Le Sentier des Ocres is a protected geological site located in a former industrial ocher quarry in Roussillon, France. The landscape is defined by high concentrations of iron oxide in the soil, resulting in vibrant red, orange, and yellow hues. Visitors follow two marked loop trails, ranging from 30 to 50 minutes in length, through natural sandy canyons and sculpted cliffs. The site is part of the Luberon massif, a region historically significant for the extraction and processing of ocher pigments. The trails are carved into soft, friable earth, requiring careful navigation of uneven terrain and sand. Natural vegetation, including maritime pines and holm oaks, grows directly from the mineral-rich sediment. The site is managed by the local municipality to preserve the fragile topography from erosion and unauthorized access. Information panels throughout the path detail the geological formation process and the history of the mining industry that once operated here.

Wear sturdy walking shoes with good grip, as the sandy ground can be slippery and uneven.
Carry plenty of water, as the open canyon landscape provides limited shade during the afternoon.
Avoid wearing white or light-colored clothing, as the ocher dust stains fabric permanently upon contact.
Do not attempt to touch or climb the cliff faces, as they are fragile and pose a rockfall hazard.
Closed annually during the winter months; check local municipal bulletins for exact reopening dates in the spring.
No smoking, no picking up sand or rocks, and strictly stay on marked paths to prevent erosion.
