The brisk blue waters of Round Valley Reservoir attract swimmers, boaters, fishermen, picnickers and campers to its scenic shore.
The 2,000 plus acre 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. At approximately 180 feet deep, its the deepest lake in New Jersey. The reservoir is stocked with lake trout.
The park offers hunting (waterfowl only), boating/canoeing, trailer & cartop launch, swimming, bathhouse, scuba and skin diving, hiking, horseback riding, mountain biking, picnic areas, playground, food concession. Cross-country skiers and sledding in the winter.
