Located beneath the city of Horse Cave, Hidden River Cave was once the source of drinking water and hydroelectricity for the community. Groundwater pollution led to its closing in 1943.

In the late 1980s, the American Cave Conservation Association relocated its national headquarters to Horse Cave to restore Hidden River Cave and open a museum and educational center at the site. A bat rehabilitation center is also in progress. Hidden River Cave is now open to visitors year-round.
