The brisk blue waters of Round Valley Reservoir attract swimmers, boaters, fishermen, picnickers and campers to its scenic shore. The Round Valley Reservoir swimming area was created by the construction of an earth dam across a narrow waterway on the west side of the reservoir, separating it from the main part of the reservoir. The reservoir covers over 2,000 acres and is approximately 180 feet deep, the deepest lake in New Jersey. It has a water capacity of 55 billion gallons. The reservoir is stocked with lake trout.
Round Valley is one of the few parks that offers wilderness camping. The campsites on the eastern side of the reservoir are accessible only by hiking or boating. The campers' parking lot is three miles away from the nearest site, reachable by a steep and rugged trail. Cross-country skiers and sledding enthusiasts congregate at Round Valley in the winter months.

Trail & Path Info
There are three marked trails at Round Valley: the Cushetunk Trail, which accesses the campsites, the Pine Tree Trail and the Family Hiking and Biking Trail. All trails are accessed from the South Parking Lot within the Day-use Area. Trails are opened year-round. Visitors should plan their trail activities so that they will be out of the park by closing and are reminded to stay on the path. Wandering off causes erosion, damage to vegetation and may, in some areas, result in trespassing onto private property. Fires are not permitted along the trails. Pets must be leashed at all times, and owners are responsible for picking up after their pets. Drinking water is available along the lower service road located in the campground.
The nine-mile Cushetunk Trail and the three-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 which makes it more suitable for experienced hikers, mountain bikers, and horseback riders. Users must follow the same trail back as it ends at the Water Supply Authority's Restricted Area and therefore, has no outlet.
The Pine Tree Trail is approximately a one mile loop and the Family Hiking and Biking Trail is 1/2 mile loop. They pass through pinewoods and are ideal for young children, birdwatchers, and seniors. The Pine Tree Trail connects the day-use area with Division of Fish and Wildlife property.
There is a fourth unmarked water trail that is approximately 1 1/2 miles. You can access it from the campers boat launch area.
There are no trails that completely circle the reservoir.
