The brisk blue waters of Round Valley Reservoir attract swimmers, boaters, fishermen, picnickers and campers to its scenic shore. The reservoir covers over 2000 acres and is approximately 180 feet deep, the deepest lake in New Jersey. It has a water capacity of 55 billion gallons and is stocked with lake trout. The park has a wilderness area for camping that is only reachable by hiking or boating to the site. The hike is a steep, rugged climb and the first campsite is 3 miles from the camper’s parking lot. Drinking water is available along the lower service road as well as several outhouses.

There are three marked trails: the Cushetunk trail which accesses the campsites, the Pine Tree trail and the family hiking and biking trail. The 9 mile Cushetunk trail and the 3 mile lower service road are multi use trails that pass through  open and heavily wooded areas. The Cushetunk trail surface is rugged, rocky and steep in places making it more suitable for experienced hikers, mountain bikers and horseback riders. It’s an out and back trail. The Pine Tree trail and family hiking trail combined are about 1.5 miles and are ideal for children and seniors. A fourth trail that is unmarked is about 1.5 miles and can be accessed  from the boat launch area.

The boat launch area is only usable with a permit or fishing license. Many come to kayak and paddle board in the beautiful crystal clear waters. Be sure to bring your Coast Guard approved flotation device. Not only is it the law but a safety precaution as well. The recreation area has a beach where swimming is permitted. The complex includes changing areas, rest rooms, showers, a first aid station and a concession stand. There are picnic areas as well as playgrounds and volleyball nets on the beachfront.
