Hopatcong State Park sits along the southwestern shore of Lake Hopatcong, New Jersey‘s largest freshwater lake, spanning 163 acres across Hopatcong Borough and Roxbury Township in Sussex and Morris counties. Established in 1922, this park has served generations of visitors drawn to the sparkling waters and wooded hillsides of the New Jersey Highlands.

The lake is the undisputed centerpiece here. A public beach with lifeguards operates during summer months, making it one of the best swimming spots in North Jersey. Beyond the sand, Lake Hopatcong offers excellent fishing for largemouth bass, hybrid striped bass, walleye, and panfish — the state regularly stocks the lake, and local anglers consider it one of New Jersey’s premier fishing destinations. Boat launches provide easy access for kayakers, canoeists, and motorboats alike.

On land, hiking trails wind through mixed hardwood forests where white-tailed deer and wild turkey are common sights. Picnic areas with grills dot the lakeshore, perfect for a family afternoon. In winter, the park draws ice fishermen and cross-country skiers when conditions allow.

The best time to visit is late June through August, when the beach is staffed and the lake is warm enough for swimming. Fall brings spectacular foliage along the shoreline. Weekdays are significantly less crowded than weekends, especially during July.

Camping availability should be confirmed directly with the New Jersey Division of Parks and Forestry, as facilities have changed over the years. The park is easily accessible from Interstate 80, putting it within reach of millions of residents across the metropolitan region.
