[3] Located in the community of Farmington, it sits on the Chestnut Ridge near Uniontown,[4] roughly 50 miles (80 km) southeast of Pittsburgh.

[12][13] Even so, by the 1930s, it was a popular attraction for church groups and visiting guests of area residents, who arranged for tours headed by Don Helmick and other knowledgeable guides.

[20] It was then purchased from the Cales later that same year by Emmett J. Boyle Jr. and Ned J. Nakles, two lawyers from Greensburg and Latrobe, who made several safety and entertainment value-related improvements, including the installation of roughly twenty-five miles of electrical cable that supported a new theatrical lighting system.

Operators offer a three-hour tour, which includes gravity hill, as well as the cavern's lower branchwork, which is unlit.

The cavern grounds also offer visitors access to a gift shop, mini-golf course, the opportunity to pan for gemstones, and fossil-study activities, and also serve as a wildlife viewing locale during operations to tourists.
