Voorhees State Park is a 1,400-acre park in Lebanon Township, Hunterdon County, established in 1929 and developed by the CCC. It is known for forested hills, multi-use trails, and the New Jersey Astronomical Association's Paul Robinson Observatory (a 26-inch reflecting telescope) with public stargazing near the campground.
The campground (Observatory Road section) has 47 tent/trailer sites with picnic tables, fire rings with grills, and two-vehicle parking, plus 2 group sites and 3 cabin-like shelters, with modern restrooms and showers. Pets and alcohol prohibited; a dump station is available at nearby Spruce Run.
Natural Features and SceneryVoorhees Campground sits within **Voorhees State Park**, a roughly 1,340–1,400‑acre tract of **forested hills, ridges, and small streams** in the Highlands region of Hunterdon County, New Jersey[1][3][9]. The landscape is dominated by **mixed hardwood forest**—oaks, maples, and other deciduous trees—interspersed with hemlock and pine stands, giving strong **spring wildflower** displays and **vivid fall foliage**[2][8]. The park is situated on elevated terrain that provides **scenic overlooks toward Round Valley Reservoir and Spruce Run Reservoir**, offering distant blue‑water views on clear days[7][8]. Trails wind through rolling hills, small ravines, and meadow openings; some follow old farm lanes, reflecting the land’s agricultural past[3][8][9]. A distinctive natural feature is the **dark‑sky environment relative to surrounding suburbs**: the park hosts an astronomical observatory, and visitors remark on the **night sky quality** for stargazing[1][3][7]. Within and near the campground, the environment is a **quiet, wooded setting** with campsites nestled among trees, creating shade and a semisecluded feel while still being close to the observatory and trailheads[1][3].
