Round Valley Recreation Area

1220 Lebanon-Stanton Road

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.

One of the best lakes in New Jersey for swimming. The water is always warm, unlike the ocean. The park is well taken care off and the beach is very clean. Life guards are very alert. It also has washing rooms and restrooms near the beach. Admission is only $5.00 for NJ residents during week days. It's totally worth it.

Love it here!! Everything is perfect. If only the other parents would keep an eye on their children so the rest of us won't have to keep exiting the water it would be great! But we had an amazing time!

I have always loved round valley. I have always gone to round valley to camp. But unfortunately like alot of things in New Jersey the park is getting worse and worse by somehwhat no fault of round valley. As you walk down the paths you can tell it's upkept but that is all the park can do. You can also see the start of old electrical hookups but are now abandoned. The beach on the opposite side of the lake has been degraded so much. There is a nice over hang with tables but the tables are all piled on top of each other,trees have fallen on the beach and weeds have grown making the beach 1/3 of what it was. Don't get me wrong the place is still beautiful and fun to camp here but the potential was great when I was a child and all of that just disappeared as I grew up. SAD!!!!
