Tucked into the rugged ravines of Morris County, Hacklebarney State Park spreads across 1,186 acres of some of New Jersey‘s most dramatic glacial scenery. Established in 1924, the park follows the Black River as it cuts through a steep, boulder-strewn gorge lined with towering hemlocks, oaks, and maples — a landscape that feels far more remote than its location in Chester and Washington Townships suggests.

The centerpiece here is the river gorge itself. Massive boulders deposited by retreating glaciers thousands of years ago create a wild, almost primeval atmosphere along the waterway. Trails wind down into the ravine and along the riverbanks, where the rushing water and dense forest canopy block out most signs of the surrounding suburbs. The main trail loop is roughly three miles and involves moderate elevation changes, with stone steps and footbridges making the descent manageable for most hikers.

Beyond hiking, visitors come for trout fishing along the Black River, which is stocked seasonally. Birdwatching is productive year-round, with warblers and thrushes filling the hemlock groves in spring and summer. Picnic areas sit along the upper ridgeline with views into the gorge below.

Camping is not available within the park, so plan this as a day trip. The best time to visit is mid-October, when the hardwood canopy erupts in color and the gorge becomes one of North Jersey’s most photogenic fall foliage destinations. Spring is equally rewarding, with wildflowers carpeting the forest floor and the river running high from snowmelt.
