Indian Echo Caverns
Indian Echo Caverns are limestone caves that are open to the public through guided tours. The known portions of the cave intersect at two passages: the "eastern" and "northern" caverns, which meet at right angles and form a large space known as the "Indian Ballroom." The large, accessible caverns were thought to have been utilized by Native Americans for storage and shelter. The caverns are a part of the same geological system which are responsible for sinkholes stretching from Hummelstown to Palmyra and as far south as Middletown.
