"Reviewers describe Marble Quarry Hiker-Biker as a spacious, attractive, and generally quiet C&O Canal campsite that works well for cyclists, hikers, and paddlers needing an overnight stop. It’s considered “typical” for the C&O but on the better end, with level tent areas and a nice setting near the river, though occasional train noise and inconsistent water pump function are noted."
