The gorge was formed by the erosion of the Luberon mountain's limestone massif.
The narrowest passages in the canyon require hikers to navigate between walls only a few meters apart.
The site is prone to rockfalls, which necessitates periodic safety inspections by local communes.
The gorge is located within the protected territory of the Luberon Regional Natural Park.
Water is rarely present in the canyon floor, as it is a karst system that drains rapidly underground.
The temperature inside the gorge remains significantly lower than on the plateau above due to limited sunlight exposure.
Gorges de Regalon is a narrow, limestone canyon located in the Luberon Regional Natural Park, carved by water erosion over millennia. The trail runs approximately 2 kilometers through a deep gorge where the walls reach heights of up to 30 meters. The narrowest section, known as the 'Stroit', features rock walls that are only a few meters apart. The route involves navigating rocky, uneven terrain, including minor scrambling and traversing a dry riverbed. Flash flooding is a primary geological and safety hazard, leading to frequent closure of the site by local authorities during and after rainfall. Vegetation in the canyon is distinctly cooler and more humid than the surrounding scrubland, supporting diverse micro-habitats. The canyon serves as a popular destination for hikers seeking geological exploration in the Vaucluse department.

Wear sturdy, closed-toe hiking shoes with good grip to manage slippery or loose stones.
Check local weather reports immediately before departure, as the site is strictly closed following heavy rain.
Carry a headlamp or flashlight if you intend to explore the deeper, shaded sections where light penetration is minimal.
Attempting to enter the gorge during or after rainfall due to high risks of falling rocks and flash flooding.
Frequently closed by municipal decree during periods of high fire risk or following heavy rainfall; verify access status via the Cheval-Blanc town hall website before arriving.
Stay on marked trails to prevent erosion, do not discard waste, and respect the fragile geological environment.
