Conewago Falls

Conewago Falls is a series of waterfalls along the Susquehanna River in Lancaster County, Pennsylvania. The water cascades over diabase rock formations that create drops and rapids across a wide stretch of the riverbed.

These falls formed through natural geological processes along the Susquehanna River and were altered by the construction of the York Haven Dam in 1904. That dam changed how water flows over the rapids and through the landscape.

Native American tribes, including Susquehannock, Iroquois, and Lenape, used elm bark canoes to navigate around these falls for trade purposes.

Access to the falls is available through the Falmouth Access area managed by the Pennsylvania Fish and Boat Commission, which can be reached from Collins Road off Route 441. The best viewing happens after rain or during high water flow, when the waterfalls are most powerful.

The diabase rocks at the falls contain numerous potholes formed by underwater sand erosion processes during the Ice Age period.
