The central mound, the Rocher de la Vierge, was formed when the Vis River abandoned its original meander loop to take a shortcut through the limestone bedrock.
The village of Navacelles at the bottom of the gorge has been continuously inhabited since the Neolithic period, supported by the river's irrigation potential.
The site is part of a larger geological formation where the Vis River flows underground in several sections before resurfacing.
The cliffs surrounding the cirque reveal horizontal strata of Jurassic limestone, documenting millions of years of sedimentation.
The area is home to rare Mediterranean flora and fauna that thrive in the microclimate created by the deep-valley insulation.
Cirque de Navacelles is a massive natural erosion amphitheater carved by the Vis River into the limestone plateaus of the Causse du Larzac and Causse de Blandas. The site features a 300-meter-deep canyon containing a central rocky spur, the Rocher de la Vierge, which remains as a remnant of an ancient river meander. Located within the Causses and Cévennes UNESCO World Heritage area, the landscape is managed to preserve its traditional agropastoral character. Visitors primarily access the gorge via cliffside viewpoints such as the Belvédère de Blandas. At the base of the gorge lies the small hamlet of Navacelles, which is situated on the alluvial fan created by the river's former path. The area is part of the Grand Site de France designation, recognizing its geological and cultural significance. Waterfalls, such as the Cascade de la Vis, are fed by the river that circumvented the spur during geological shifts.

Bring sturdy hiking boots for the steep trails leading from the rim to the valley floor.
Pack adequate hydration and sun protection, as the limestone cliffs provide limited shade during midday.
Visit the Belvédère de Blandas first for a panoramic perspective before driving down to the hamlet.
Attempting to drive a large campervan or RV down the narrow, winding access road into the valley floor, which is restricted and dangerous.
Respect private property within the hamlet of Navacelles and follow marked trails to protect the fragile limestone soil from erosion.
