Marble Hill Natural Resource Area showcases a rich mix of upland deciduous forest, seasonal color, and sweeping river views. In late spring and early summer, vibrant stands of rhododendron add bursts of color along the trails. Roughly four miles of paths offer changing perspectives of the Delaware River throughout the year. A well-traveled segment of the Warren Highlands Trail passes through the park, linking Marble Hill to other points of interest across the county and making it an easy stop for hikers looking to experience both natural beauty and a sense of connection to the wider NJ Highlands landscape.
