About The Warren Highlands Trail

The Warren Highlands Trail highlights the natural, scenic, and cultural beauty of Warren County, New Jersey, which is nestled within the majestic Highlands Region.

A Local, National Treasure

Encompassing over 1.5 million acres in Pennsylvania, New Jersey, New York, and Connecticut, the United States Forest Service recognizes this region as nationally significant for its large tracts of public open space, quality drinking water for millions of residents, large areas of wildlife habitat, relationship to the Appalachian Mountains, and its historical links to both the American Revolutionary and American Civil Wars. Within New Jersey alone, the Highlands Region contains nearly 860,000 acres of rolling hills, pastoral valleys, steep ridges, diverse forests, numerous water bodies, and critical wildlife habitats that serve as a significant green belt along the East Coast’s metropolitan areas.

Easily Accessible

Located in Northwestern New Jersey, Warren County has become a key gateway into the Highlands Region. With over 170,000 acres of land in the Highlands Region, nearly 53,000 acres of public open space, more than 22,000 acres of preserved farmland, dozens of historic villages and charming downtowns, and some of the best hiking, biking, and paddling found anywhere in the state, Warren County is a popular regional destination for outdoor enthusiasts. Less than a 2-hour drive from Philadelphia and only about a 1-hour drive from New York City, the Warren Highlands Trail is not only easily accessible from Interstate Routes 78 and 80, but offer millions of east coast residents the opportunity to explore the beautiful Highlands Region and enjoy New Jersey’s friendly countryside.

Spectacular Features

Showcasing the exceptional Highlands Region and pleasant Warren County countryside, the Warren Highlands Trail extends over 52.4 miles from the Delaware River in the west to the Musconetcong River in the east. From its western terminus at the iconic Northampton Street Bridge in Phillipsburg, hikers can connect with the Morris Canal Greenway Trail on the New Jersey side or with the Delaware and Lehigh Trail (D&L Trail) across the bridge in Easton on the Pennsylvania side.
