A Local, National Treasure

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

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.
