The name translates to 'Well of Hell,' a traditional French toponym assigned to narrow, dangerous gorges that were historically feared by locals.
The site serves as a natural drainage point where surface water erosion has exposed layers of Bajocian-aged limestone.
The ravine acts as a wildlife corridor, allowing species that prefer humid, shaded environments to thrive despite the regional agricultural land use.
Le Puits d'Enfer is a deep, narrow gorge carved into the limestone bedrock by the Chambrille River in the Deux-Sèvres department. The site is characterized by its steep, rocky banks and a densely forested valley floor that creates a microclimate distinct from the surrounding plains. The geological formation reveals stratified layers of the Jurassic limestone plateau, common to this region of western France. A wooden footbridge spans the narrowest section, providing a direct vantage point over the river currents below. The area is integrated into local hiking circuits that connect with the wider Haut-Val de Sèvre trail network. Its location near Exireuil marks a notable topographical shift in the otherwise flatter landscape of the Gâtine Poitevine.

Wear sturdy, closed-toe footwear with good grip, as the terrain near the riverbanks becomes slippery when damp.
Bring insect repellent during the summer months, as the shaded valley environment can attract mosquitoes.
Check local weather forecasts before visiting, as high rainfall can cause the narrow gorge to flood or make the wooden paths dangerous.
Attempting to climb the steep, unmaintained banks of the gorge, which pose a significant falling hazard.
Stick to marked trails to preserve the fragile limestone edges and prevent erosion; keep pets on a leash.
