Bluespring Caverns Poster
Visit Bluespring Caverns and take a boat tour down the longest navigable underground river in the United States! The cave system was discovered as early as the 19th century. Up until 1913, the entrance used was the exodus of a spring which drained into the White River. However, a dam completed in 1913 on the White River closed off this entrance. In 1940, a second entrance was created after a severe storm passed through the area. A small pond on the farm of George Colglazier vanished overnight, becoming a sinkhole, and the present day entrance into the cave system.
