Hidden River Cave is located directly beneath the City of Horse Cave in south central Kentucky. The American Cave Conservation Association relocated their national headquarters to Horse Cave in 1987 with the goal of restoring Hidden River Cave and establishing a museum and educational center at the site. Today, thousands of tourist visitors and school children annually tour Hidden River Cave and the American Cave Museum at the caves entrance. The cave, which has been called "the greatest cave restoration success story in the United States" is now open year-round to visitors.
