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.

Easy. Perfect hike to go on with a big dog. The water is beautiful!

Fall blooms coming into peak. Damp and chilly day but once you get moving warms up. Nice and easy. Blue trail into the green. Hugged the beach for a bit then up through a pine grove. One minor incline and all ground. Good for beginners and children. Picked a couple of ticks off the dog and the wife when we got home.

Great hike though not quite a true loop. Gets overgrown as the loop gets closer to the end. Hiked with my wife and three daughters age 6,5 and 2. Carried the two year old half of it but older daughters loved it. Very scenic and pleasant walkabout

Very nice place. $10 parking fee so bring lunch and enjoy a nice view of the water.
