The Delaware and Raritan Canal State Park is one of central New Jersey's 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.

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.

• Rent a canoe in Griggstown, and spend the day maneuvering through the Delaware River's waterway.
• Hike from the park office to 3,000-acre Six Mile Run Reservoir, one of Central New Jersey's most hidden recreational resources for hiking, biking, and horseback riding.
