Hidden River Cave & American Cave Museum
Hidden River Cave
A cave with an underground river right beneath the center of Horse Cave town, once polluted and later restored, with an attached museum on cave science.
Hidden River Cave lies beneath the main street of Horse Cave. Its huge entrance drops steeply, and an underground river flows through the cave. Sewage discharge caused foul odors in the mid-20th century and forced its closure, but after remediation it reopened in the 1990s and became a well-known example of karst groundwater protection. The tour takes about 1 hour and passes a suspension bridge inside the cave, as well as blind fish and other cave creatures. Other activities include caving and zip-lining. Admission includes the American Cave Museum, which covers cave geology, ecology and the history of local cave exploration.
