Bluespring Caverns, Show cave in Lawrence County, Indiana, US
Bluespring Caverns is a limestone cave system with an underground river flowing through extensive surveyed passages beneath the surface. The water maintains a constant cool temperature year-round, and the cave system stretches across miles of connected chambers and tunnels.
A storm in 1940 created a sinkhole on a local farm, revealing the entrance to this cave system for the first time. This sudden discovery opened access to a vast underground world that had remained hidden until then.
The cave has been a place where families share their land with visitors seeking to explore the underground world, creating a tradition of hospitality and protection. Today, travelers experience this connection between people and the subterranean landscape firsthand.
Boat tours guide visitors along the underground river and take about an hour, with the best conditions in spring and summer months. Bring comfortable shoes and light layers, as the passages stay cool year-round and walkways can be damp.
The cave is home to rare sightless fish and other creatures that have adapted completely to life in total darkness. These underground inhabitants are found nowhere else and make the site special for those interested in nature's adaptations.
