About Farny
Farny State Park in Morris County protects over 5,000 acres of forested highlands in the New Jersey Highlands — a ridge system running from the Hudson River to the Delaware Water Gap. The park’s iron-rich rock supported a colonial-era mining industry — New Jersey was one of the leading iron producers during the Revolution. Farny’s forests have regenerated from centuries of logging and mining, now supporting black bears, bobcats, and timber rattlesnakes.
Things to Do
Hiking the Four Birds Trail (10 miles), mountain biking, fishing, hunting (seasonal), cross-country skiing, and exploring regenerated forest on former iron mining land.
Plan Your Visit
Farny provides 5,000+ acres of trail-based recreation — no camping or developed facilities. The Four Birds Trail (10 miles) connects to Split Rock Reservoir for swimming. The park sits in bear country — black bears are common in the NJ Highlands. Nearby Wharton and Allamuchy state parks extend the trail network. Morristown National Historical Park (Washington’s winter headquarters) is 15 miles east. Free admission; open dawn to dusk.
Nature & Wildlife
The New Jersey Highlands support one of the densest black bear populations in the eastern US — over 3,000 bears in the state. Farny’s forests harbor bobcats, timber rattlesnakes, and barred owls. The iron-rich streams support native brook trout. Old-growth hemlock groves survive in ravines too steep for 19th-century loggers. The Four Birds Trail is named for four threatened species: red-shouldered hawk, Cooper’s hawk, barred owl, and long-eared owl.

Pro tip: The park is named for Henry Farny — ruins of iron forges and mines remain in the forest. NJ Highlands: The Highlands region supplies drinking water to 70% of NJ’s population — its protection is critical for the state.

Frequently Asked Questions
Did NJ have iron mines?
Yes — New Jersey’s Highlands region was one of the most important iron-producing areas in colonial and early America. Bog iron and magnetite deposits were smelted using charcoal from local forests. NJ iron forged cannons and cannonballs for the Revolution. The Morris Canal (1831) was built specifically to transport coal and iron. Mining declined as richer deposits were found in Pennsylvania and Minnesota. Ruins of forges and mine shafts dot the Highlands forests.
