Cabin John Stream Valley Trail

Cabin John Stream Valley Park Trail Map LocatorDescription

This trail is located near major highways but still offers an unexpected sense of solitude and natural beauty. The hiker-only portion of the trail from River Rd. to MacArthur Blvd. is one of our Best Natural Areas.

The Potomac Appalachian Trail Club helps maintain the trail. Since the trail is in an urban area, users must be careful when crossing roads as they carry high volumes of vehicular traffic. A portion of the trail traverses Cabin John Regional Park.

Unless noted otherwise on the map, trails marked “Natural Surface” and “Hard Surface” are "Shared by All" trails which includes hikers, bikers and equestrians. Additional information about permitted uses of Park trails is available on our Trail User Information page.
