Doux de Coly (zárva? / reportedly closed)
Access reportedly closed – check before planning. This Périgord resurgence near Saint-Amand-de-Coly is one of Europe's classic long sumps: a bedding-plane gallery at about 8 m runs for 275 m, a shaft drops to -35 m and a deep gallery continues at an average -53 m for over 2 km. Olivier Isler reached 4,250 m by 1998, and German divers pushed it to 5,675 m in 2002.
