Round Valley Recreation Area Overview

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 about 2,350 acres and is approximately 180 feet deep, the second deepest lake in New Jersey. It has a water capacity of 55 billion gallons. The reservoir is stocked with lake trout.

Round Valley is the only state park 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.

Round Valley Reservoir covers 2,350 acres and is approximately 180 feet deep. It has a water capacity of 55 billion gallons. The reservoir was formed in 1960 by the New Jersey Water Authority by constructing two large dams and flooding the large valley. The deep valley was caused by erosion of the soft sedimentary rock. Questions about the construction that you are observing around the reservoir? Find more information about the Round Valley Reservoir Project here.

The Cushetunk Mountain, lying on a bed of igneous rock in Round Valley at the east end of the lake rises 500 feet above the shoreline and 834 feet above sea level. The Lenape called the mountain "Cushetunk" meaning "place of hogs" after the wild hogs found there.

Hiking
Round Valley has four marked trails; the Cushetunk Trail, Pine Tree Trail, Family Hike and Bike Trail and Water Trail. All trails are accessed from the south parking lot and are open year-round. The Cushetunk Trail surface is rugged, rocky, and steep in places which makes it more suitable for experienced hikers. Users must follow the same trail back since it has no outlet.

Horseback Riding
Horseback riding is permitted on the Cushetunk Trail and the three-mile campground trail.

Mountain Biking
Mountain biking is permitted on the Family Hike and Bike Trail, Cushetunk Trail and the three-mile campground trail.

Trails
There are four marked trails at Round Valley: the Cushetunk Trail, which accesses the campsites, is a 8.35 mile trail that traverses the Cushetunk Mountain chain and passes through both open and heavily wood areas. The trail surface is rugged, rocky and steep in places. The Pine Tree Trail and the Family Hiking and Biking Trail are both loops approximately one mile long. The trails pass through pinewood and are ideal for young children, birdwatchers and seniors. Biking is not allowed on the Pine Tree Trail. The Water Trail does not loop, but you may connect to the Pine Tree Trail at the end by going up the hill left of the gate at the impoundment dike. This trail is approximately a two mile hike roundtrip. 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 to 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.
