Directions to the trailhead: The parking lot for the Five-Mile Lock trail access is located on the east side of Easton Avenue just north of I-287, exit 10.  You must be going northbound on Easton Ave. to enter this parking lot.

The hike: Built in the 1830's, the Delaware and Raritan Canal traces a rainbow-shaped arc across central New Jersey as it connects its two namesake rivers.  In the early 1800's, waterways formed the country's main highways, and the canal's construction not only shortened the water route between Philadelphia and New York City by 100 miles but also eliminated the need to take boats into the exposed waters of the Atlantic Ocean.  The canal saw heavy traffic for over 40 years, and it became a primary means to get Pennsylvania coal to New York City.  In fact, the canal continued to operate until 1932, long after most canals had been supplanted by the railroad.

            Today most of the canal still retains water, and since 1974 the canal's towpath has been owned and maintained by the State of New Jersey as Delaware and Raritan Canal State Park.  The linear park extends for 70 miles, and the wide natural-surface path is popular for jogging, biking, and of course hiking.  The trail can be accessed at many points.  The segment described here not only gives a good taste of the canal and riverside areas but also passes a couple points of historical interest.  Thus, this segment makes a better than average hike for a wide, flat, and straight canal towpath.

Five-Mile Lock

            From the parking lot, walk down to the old canal and cross the canal on a metal grate walkway where water enters the old Five-Mile Lock.  The water entering the old lock makes for a scenic and noisy man-made waterfall even with the concrete lock as a backdrop.  Directly across the canal sits the towpath; turn left to begin heading upstream with the canal on your left.  There were quite a few people around the lock when I came here on a warm and humid Saturday morning in early September, but the traffic thinned as I got further upstream.

Hiking the canal towpath

            The wide gravel towpath makes for flat, easy hiking.  Some walls and other old canal remnants passed as you hike add some historical interest.  Numbered concrete obelisks mark each mile, and soon you pass mile marker #37.

            Throughout the hike the canal's calm, still waters remain to your left.  The Raritan River lies to your right, but it never comes in sight on this hike due to dense forest featuring many black walnut trees.  1 mile into the hike, the trail angles right to briefly leave the canal bank.  I saw several deer in this area, and a flock of Canada geese greeted me with honking further upstream.

            Ignore a wooden bridge that exits left at 1.4 miles; it leads to Canal Crossing Condominiums.  At 1.6 miles, you reach the small parking lot at the Main Street road crossing in the Borough of Bound Brook.  Several interpretive signs at this crossing describe the Revolutionary War Battle of Bound Brook, which took place here on April 13, 1777.

South Battlefield, Battle of Bound Brook

            The Battle of Bound Brook started as a fight for the stone bridge over Bound Brook, which empties into the Raritan River just north of here.  The battle turned into a rout when 1000 Hessian soldiers fighting for the British marched north on present-day Easton Avenue and dislodged the Patriots from their positions.  This battle exemplifies the frustrations and defeats the Patriots suffered during the early days of the Revolutionary War.

Returning downstream

            The Main Street access and Bound Brook South Battlefield mark a good place to turn around.  Benches for resting and rehydrating are available near the road intersection to the south.  Walk downstream along the towpath to return to Five-Mile Lock and complete the hike.
