Located in Farmington, Pennsylvania, it sits on Chestnut Ridge near Uniontown, about 50 miles (80 km) southeast of Pittsburgh.

The steep slope of some passageways causes an optical illusion known as a gravity hill. The illusion of a ball rolling uphill is an illustration of this effect and a mainstay for the businesses one-hour guided family tour of the network. The business also features other accommodations such as a gift shop, mini-golf course, and panning for gemstones and fossils activities.
