Swartswood State Park holds a quiet distinction as New Jersey’s first state park, established in 1914 in the rolling hills of Stillwater Township, Sussex County. Spanning 3,460 acres in the state’s northwestern corner, the park is anchored by two glacial lakes — Swartswood Lake and Little Swartswood Lake — that give it a character more reminiscent of the Adirondacks than the Jersey Shore.

Swartswood Lake is the main draw, offering a sandy swimming beach, boat launches, and some of the best freshwater fishing in North Jersey. Anglers target largemouth bass, pickerel, and panfish in its clear waters, while kayakers and canoeists enjoy miles of shoreline largely free of powerboat traffic. The surrounding woodlands are laced with trails for hiking and mountain biking that wind through hardwood forests and along ridgelines with views of the Kittatinny Valley.

The park’s campground is a solid option for families and weekend explorers, with wooded sites set back from the lake. Winter transforms the landscape into a destination for cross-country skiing and ice fishing when conditions allow.

The best time to visit is late May through early October, when the lake is open for swimming and the forests are at their fullest. Fall brings spectacular foliage across Sussex County, and the campground stays open into autumn for those who prefer cooler nights and thinner crowds.

For a state park that’s been welcoming visitors for over a century, Swartswood remains one of New Jersey’s most understated outdoor escapes.
