The Capital Crescent Trail is the main artery of D.C.’s network of walking, jogging, and cycling routes. Built on the former rail bed of the Georgetown Branch of the B&O Railroad, the 11-mile trail connects the Georgetown neighborhood of D.C. with the Maryland suburb of Silver Spring. Traveling along the Potomac River and through the wooded parks of Little Falls and Rock Creek, the path is a dynamic adventure that goes over bridges, under tunnels, and past Civil War forts and batteries. Depending on the amount of time you have, shorten the route with a loop along the C&O Canal Towpath, or lengthen it by returning on the Rock Creek Park trail to create a 22-mile circuit. Note: There is a street detour from Bethesda to Silver Spring due to construction.
