Long Pond Ironworks State Park sits on nearly 7,000 acres of rugged Highlands terrain in West Milford, New Jersey, where centuries of ironmaking history meet some of the state’s wildest backcountry. Established as a state park in 1974, the land preserves the ruins of a colonial-era iron forge that supplied munitions during the American Revolution and operated well into the 1880s. Stone furnace walls, waterwheels, and workers’ housing foundations still stand along the Wanaque River, making this one of the most atmospheric historic sites in North Jersey.

Beyond the ironworks ruins, the park is a gateway to the Norvin Green State Forest trail network. Hikers can tackle the Hewitt-Butler Trail for sweeping ridgeline views or follow the Sterling Ridge Trail past glacial erratics and hemlock ravines. The Wanaque River and Monksville Reservoir offer fishing for smallmouth bass and pickerel, while mountain biking routes draw riders to the rocky singletrack that crisscrosses the Highlands.

Birdwatchers should visit in spring migration season when warblers fill the hardwood canopy, though fall foliage in October transforms the park into one of Passaic County’s best leaf-peeping destinations. Summer brings lush green forests and cool river corridors perfect for escaping suburban heat.

The historic village area near the main entrance is easy to explore in an hour, but the backcountry trails reward a full day. Wear sturdy boots — the terrain is rocky and uneven. Parking fills quickly on autumn weekends, so arrive early.
