The cave is estimated to be approximately 150,000 years old.
It contains 25 distinct species of cave-dwelling organisms, including the cave spider and centipedes.
The interior temperature remains constant at 15 degrees Celsius regardless of external seasonal changes.
The cave holds the nickname 'Subterranean Palace' due to the intricate shapes of its rock formations.
A significant portion of the cave was officially designated as a natural monument by the South Korean government in 1976.
Gosu Cave is a limestone karst cave system in Danyang, South Korea, known for its extensive stalactite and stalagmite formations. Designated as Natural Monument No. 256, the cave spans approximately 1.7 kilometers, with roughly 940 meters open to the public. The cave features a complex interior with high ceilings and narrow passages equipped with metal staircases and walkways. Visitors navigate a vertical incline that rises through the subterranean structure. The cave environment remains consistently cool year-round due to its depth and natural ventilation. Geological features inside include the 'Lion Rock' and the 'Great Hall,' which demonstrate unique rock crystallization processes. The cave is part of a larger geological network common in the Danyang region's karst landscape.

Wear non-slip, closed-toe walking shoes as the staircases and paths are often damp and slippery.
Bring a light jacket, as the humidity and cool temperatures can become uncomfortable during longer stays.
Avoid carrying large bags or bulky backpacks, as the cave passages are narrow and steep.
Attempting to climb off the designated metal walkways or exploring unlit side passages, which are restricted for conservation and safety reasons.
Open year-round, but may close temporarily during extreme weather events or geological safety inspections.
Do not touch the stalactites or stalagmites, as human skin oils can permanently damage their mineral growth; photography is permitted but tripods are generally discouraged in narrow sections.
