Indian Echo Caverns

Indian Echo Caverns is a show cave in Derry Township (Dauphin County) near Hummelstown. The limestone caves are open for the public to visit via guided tour.
The entrance to the caverns used by modern visitors is located in a bluff along the Swatara Creek. The known portions of the caverns represent the intersection of two passages: the "eastern" cavern and the "northern" cavern, which meet at right angles to form a large space known as the "Indian Ballroom." Given the large and accessible natural openings the caverns were likely utilized by Native Americans for storage and shelter, however no evidence of such use has survived. The location was previously known as Wilson Cave, Hummelstown Cave, Stoverdale Cave, Giant's Cave, and Indian Cave. It was renamed Indian Echo Cave but has more recently been known as Indian Echo Caverns.

The same geological system of which the caverns are a part is responsible for many sinkholes in an area stretching from Hummelstown to as far as Palmyra, and as far south as Middletown.
