A premiere site along the historic Morris Canal Greenway, Port Murray Park offers visitors the opportunity to view a significant section of the historic Morris Canal, portions of which still hold water today. Visitors can walk along sections of the towpath where mules used to slowly pull long canal boats along through the water. In use from the 1820s to the 1920s, the historic Morris Canal stretched 107 miles from the Delaware River along Phillipsburg to the Hudson River along Jersey City. Overcoming a height elevation of 914 feet using 23 locks and 23 inclined planes, the canal became known as the "Mountain Climbing Canal" and was a major engineering feat of its day.
Port Warren Park is also home to the historic remnants of the early 20th century trolley line, built by the Easton-Washington Traction Company, which ran from Phillipsburg to Port Murray. Encompassing over 189 acres of preserved land, the park consists of predominantly upland forest with pockets of wetlands and meadows, as well as a small tributary to the Musconetcong River.
Port Murray Park is owned by the County of Warren and managed in partnership with the Highlands Community Service Project, the New Jersey Youth Corps, the Metro Trails Hiking Group, and the Morris Canal Committee.
