Visitors descend deep underground to Hidden River Cave. There, guides lead 60-minute treks to explore the depth's subterranean river, sharing information on cave formation, as well as the turn-of-the-century hydroelectric system that once powered the town. Guests can then rappel 70 feet down into the mouth of the cave, or be hooked securely into a 280-foot zipline for an aerial look at the cavern.
American Cave Museum & Hidden River Cave
After spending millions of years out of sight, wiling away the time by boring a cave deep into the earth, the Hidden River powered the town above with hydroelectricity before pollution forced it to close off from human eyes again. 50 years later, a recovery project restored Hidden River Cave, and today its depths play host to tours of the generator's remains and the underground river still flowing more than 100 feet below the ground.
Hidden River is one of the largest privately operated caves in the Mammoth Cave area, and along with hands-on exploration, American Cave Museum & Hidden River Cave spreads knowledge and awareness with two stories of educational exhibits. There, visitors explore topics such as prehistoric explorers, the history of saltpeter mining, and how to discern stalactites from walruses stuck in the cavern's ceiling.
