Originating from the southwestern mountains of Pennsylvania, Sideling Hill Creek tumbles its way down the steep, forested, shale cliffs of western Maryland before it finally spills into the Potomac River.
The preserve has several trails so visitors can explore the variety of species and natural communities that exist at Sideling Hill Creek Preserve. Admission is free.
