Cave of Reveillon

The Cave of Reveillon is a pit cave that descends through a deep vertical opening into the earth, showing the characteristic steep drop of a sinkhole formation. The site combines this shaft structure with a losing stream, where surface water visibly enters underground channels.

The cave formed over millions of years through the erosion of limestone in the Quercy region by water and natural forces. This sinkhole developed as part of the underground landscape that characterizes this area of France.

The cave carries the regional Occitan name Cròs de Revelhon, reflecting how locals have traditionally connected with this natural feature. The name itself shows the importance this geological formation holds within the local landscape and community knowledge.

The site is accessed through marked paths near Alvignac that lead to the cave entrance. Visitors can orient themselves easily once at the location to explore the formation safely.

Here visitors witness a remarkable phenomenon where surface water abruptly enters underground channels and vanishes from sight entirely. This interplay between visible waterflow and hidden subsurface drainage makes the location an interesting example of how water shapes the Quercy landscape.
