Protecting over 2,000 acres of the rugged Bearfort Mountain, Abram S. Hewitt State Forest is a premier destination for serious hikers in northern New Jersey. Situated in West Milford, this hike-in only forest boasts some of the most dramatic glacial topography in the state, featuring exposed conglomerate rock ridges, hidden wetlands, and sweeping panoramic views of Greenwood Lake.
Hiking and Trails
Abram S. Hewitt State Forest is accessible exclusively on foot, making it a rugged, pristine wilderness experience. The trails here are notoriously rocky and steep, demanding proper footwear and preparation, but the rewards are spectacular.
The Bearfort Trail
The white-blazed Bearfort Trail (approx. 3.0 miles) is the main artery challenging hikers with steep ascents directly up the rocky spine of Bearfort Mountain. It winds past erratic glacial boulders and offers breathtaking overlooks of Greenwood Lake and the surrounding highlands.
The Appalachian Trail Connection
The legendary Appalachian Trail crosses through the northwestern corner of the forest. Backpackers frequently utilize the state forest trails to connect with the A.T. as they traverse the Wawayanda plateau into New York State.
Surprise Lake and Scenic Overlooks
By connecting the Bearfort Trail with the yellow-blazed Ernest Walter Trail (1.9 miles), hikers can reach Surprise Lake, a picturesque, secluded glacial tarn sitting high on the ridge. The route to the lake requires scrambling over the “Puddingstone” conglomerate rock that characterizes the region.
Wildlife and Ecology
Part of the Northeastern coastal forests ecoregion, the forest is a dense mix of hemlock and oak. The varied terrain—from dry, rocky ridges to deep, shaded ravines and wetlands—supports a rich diversity of wildlife. It is a popular, albeit challenging, area for hunting, birdwatching, and, in winter, rugged cross-country skiing along the flatter woods roads.
