The Tillman Ravine and Stokes State Forest Loop is a 5-kilometer circuit trail in Sussex County, New Jersey, recognized as one of the most ecologically distinctive short hikes in the northwestern part of the state. The trail begins at the Tillman Ravine Natural Area parking lot off Route 206 North in Branchville, within Stokes State Forest (1 Coursen Rd, Branchville, NJ 07826). Parking is free and the lot accommodates approximately twenty vehicles.
The route descends into Tillman Ravine — a deeply carved hemlock gorge formed by glacial meltwater — where Tillman Brook tumbles over exposed sandstone ledges, creating a series of small plunge pools and moss-covered cascades. The forest canopy within the ravine consists almost entirely of Eastern hemlock, whose dense shade maintains cool, moist conditions year-round, making this one of the finest summer hikes in northwestern New Jersey. Wildflowers, ferns, and liverworts carpet the ravine floor in spring.
The trail surface within the ravine is compacted dirt and exposed root with occasional stone steps; the ridge section completing the loop follows a wider forest path with more moderate footing. The elevation gain of 120 meters is concentrated in two short pitches — the descent into the ravine and the climb back out to the ridge. No technical skills are required, but hiking boots with ankle support are recommended due to rooted terrain and wet rocks near the brook crossings.
The loop takes approximately two hours at a comfortable pace, with most hikers spending additional time photographing the cascades and pools. A natural turnaround point for those not completing the full circuit is the lower cascade at the base of the descent, roughly 1.5 kilometers from the trailhead. No potable water is available on the trail; all water should be carried from the trailhead. Restrooms are located at the Stokes State Forest headquarters on Coursen Road, a short drive away. The trail connects to a broader network within Stokes State Forest including links to the Appalachian Trail.

Tips for visiting
- Wear waterproof hiking boots — the ravine floor has wet rocks and brook crossings that become slippery after rain.
- Visit in late April or May for the best combination of water flow, wildflowers, and cool temperatures.
- Apply tick repellent before hiking; the ravine moist forest is prime habitat for deer ticks from spring through fall.
- The ravine section is narrow and gets crowded on weekends; arrive early morning to have it largely to yourself.
- Carry at least 1.5 liters of water and a snack — no food or potable water is available along the trail.
When to visit
Late April to mid-May for peak spring water flow and wildflowers on the ravine floor. The hemlock canopy keeps the ravine comfortable even in July and August. Avoid icy winter conditions when the rocks and brook crossings become dangerously slippery.
Accessibility
The Tillman Ravine trail involves steep descents, rooted terrain, and stream crossings that make it inaccessible for wheelchair or stroller users. No paved or hardened surface trails exist within the ravine area; the natural surfaces begin immediately from the parking lot.
