Delaware & Raritan Canal State Park: Kingston to Rocky Hill Professional Review and Guide
"The red shale, sandstone, and argillite formations of the Piedmont, stretching between Trenton and New Brunswick, rise to a mere 57 feet above sea level. This so-called “narrow waist” of New Jersey— just 44 miles wide— long tempted entrepreneurs as a potential canal shortcut between Philadelphia and New York City. While William Penn may have dreamed of a water crossing of the narrow waist, it wasn’t until 1830 that the project got launched. By then, the Erie Canal had shown the way, and canal building was all the rage in America. Railroad competition finally killed the D&R in 1932.
Today the “big ditch,” once the pride of American industrialists, is a fifty-eight-mile-long greenway and state park where Piedmont flora and 200 bird species flourish. The park includes a thirty-six-mile stretch beginning near Bordentown and ending at New Brunswick, plus a twenty-two-mile feeder canal on the Delaware River. This 4.0-mile circuit hike passes along both sides of the tree-shaded D&R Canal between the sleepy towns of Kingston and Rocky Hill, and explores the flood plain of the Millstone River."
