The Delaware and Raritan Canal State Park is one of central New Jerseys most popular recreational corridors for canoeing, jogging, hiking, bicycling, fishing and horseback riding. The canal and towpath are part of the National Recreational Trail System. The 70-mile linear park is a valuable wildlife corridor connecting fields and forests. With its 19th-century bridges, bridgetender houses, past and present locks, cobblestone spillways and hand-built stone-arched culverts, the canal is a tremendous attraction for history lovers. The upper reach of the feeder canal wanders through quaint New Jersey towns along the Delaware River such as Stockton and Lambertville. The main canal passes the Port Mercer canal house, through the charming village of Griggstown to Blackwells Mills, ending up in New Brunswick. Canoes can be rented at Griggstown and Princeton from private concessionaires. Most of the canal system remains intact today and is a reminder of the days when the delivery of freight depended upon a team of mules or steam tugboats. Nearly 36 miles of the main canal and 22 miles of the feeder canal still exist, with many historic structures along the canal.
James W. on Delaware and Raritan Canal Trail
This trail is close to and has access from New Brunswick / Piscataway and Highland Park. Easy to enter from Johnson Park. Hardly any crowds, no incline and perfect for running and cycling. Also cool as you get to spot turtles, fishes and sometimes snakes in the canal.
Very beautiful scenic view of the Delaware River, along side the tow path where old style barges use to be used for cargo transport. It's only 4.2 miles of easy walk on pretty level gravel terrain.
Where Princeton goes to stretch its legs. You can take the tow path in bite-size bits, from Frenchtown PA to Millstone NJ, or combine a bunch of them. The Princeton to Kingston stretch runs alongside Lake Carnegie. The D&R makes for pleasant, non-strenuous (it's dead level the whole way) walking or biking.
