The Marsden Tract Group Campground is located at Mile 11.5 on the C&O Canal Towpath, between the Carderock Recreation Area and Angler’s Inn. The group campsites are nestled in the woods between the Canal and the Potomac River and they are a short distance from many recreational opportunities. Fishing, rock climbing, boating and hiking are but a few possibilities while staying at Marsden Tract. (Note: A Maryland Fishing License is required in order to fish in the Canal, if you are over 16. Either a Maryland or Virginia Fishing License is required in order to fish in the river.)

The campground has three group campsites: group campsite #1 will accommodate up to 15 campers; group campsites #2 and #3 will accommodate up to 30 campers at each site.  Each campsite has a picnic table and a fire ring. Portable toilets are located between group campsite #1 and group campsite #2. Potable water is a short walk up the towpath and across the footbridge (may not be available during cold winter months). NO VEHICULAR traffic is allowed on the towpath and access to the campsites is by FOOT ONLY.
