Located in northwestern New Jersey, Warren County is home to more than 110,000 residents. Bordered by Hunterdon, Morris and Sussex counties in New Jersey and Monroe, Northampton and Bucks counties across the Delaware River in Pennsylvania, Warren County is a special place with a rich history and beautiful scenery, as well as many employees and volunteers ready to serve you.


     A “Grand Re-Opening” of the Marble Hill Natural Area Preserve was held Sunday, April 14 to celebrate improvements made to the recreation area. The 270-acre preserve is owned by the County and adjoins 105 acres of state open space and 105 acres of municipal parkland.
    With the help of the state, township and volunteers, Warren County cleared and blazed nearly 4 miles of new trails, installed multiple informational kiosks and interpretive signs, and created additional parking areas along River Road and Marble Hill Road.
   Situated along the Delaware River just north of Phillipsburg, the preserve’s contiguous forestland provides coverage for neotropical song birds and other migratory song birds that use the river as a flyway during migration. Visitors are invited to follow newly established trails through dense thickets of rhododendron, which are particularly colorful in late spring and early summer.
