Trou du Diable

Trou du Diable, or Devil’s Hole, is a cave in Portneuf Regional Natural Park near Saint-Casimir, Quebec, recognized as the province’s second-largest cave with just over a kilometer of dry underground galleries. Its passages include vortex-shaped formations in the pot gallery, large chambers, underground tributaries, and relatively small concretions that point to the importance of dissolution in its formation. The cave also holds a strong place in local folklore, with stories linking its waters, sounds, and vapors to the damned, purgatory, and hell. Today it is valued both as a natural laboratory for scientific study and as a landscape tied to one of Quebec’s enduring cave legends.
