The D&R Canal trail is a recreational trail in the U.S. state of New Jersey. The 77-mile (124 km) trail is made up of three segments that transverse three counties: a canal towpath from New Brunswick to Trenton; a canal towpath/rail trail from Trenton to Bull's Island; and a rail trail from Bull's Island to Frenchtown. The three combined trails together form the largest completed trail in New Jersey. Much of the trail runs along the existing Delaware & Raritan Canal within the Delaware and Raritan Canal State Park. There is no direct connection between the main and feeder canal paths along the Delaware River. Signed on-street connections are required to traverse the trail system in its entirety. The proposed Capital to Coast Trail is planned to connect to the D&R Canal Trail. The trail is also part of the East Coast Greenway, a 3,000 mile long trail system connecting Maine to Florida.
