About
Marble Quarry Hiker-Biker Campsite sits at milepost 38.2 along the Chesapeake and Ohio Canal towpath, positioned between the Potomac River and the historic canal. This primitive campsite serves as an overnight stop for those hiking, biking, or riding horseback along the 184.5-mile towpath. The site provides basic amenities including a chemical toilet, picnic table, and grill for cooking. As with all hiker-biker campsites on the C&O Canal, this location operates on a first-come, first-served basis with no fees or reservations required. However, overnight stays are limited to one night only to ensure availability for through travelers. The campsite is located in close proximity to the Potomac River and may be subject to flooding after heavy rains. Water is available seasonally at the site but is non-potable and must be filtered, chemically treated, or boiled before use. Water service is turned off from mid-November through mid-April each year. Fires are restricted to the provided grill or to portable grills positioned off the ground. Firewood may be collected from dead material on the ground for use in the campground only.
