Overview
Hickory Creek Wilderness is Pennsylvania's only federally designated wilderness within a national forest, 8,649 acres of old hemlock forest, creek bottomlands, and rolling plateau terrain in the heart of Allegheny National Forest. The 12-mile loop through the wilderness is the longest and most demanding trail in the forest, and it offers something increasingly rare in the mid-Atlantic: a backcountry experience where the sounds of roads and machines genuinely disappear.
The trail is well-documented on maps but unmarked inside the wilderness (wilderness designation prohibits trail signs and blazes within the boundary). Navigation requires attention, particularly at creek crossings and junctions. Download the USFS Allegheny trail map or a topographic app before you leave the trailhead. Cell service is completely absent throughout the area.
No permit is required. Dogs are permitted on leash. Dispersed camping is allowed throughout the wilderness.
The Route
Miles 0 to 1.5: Trailhead to the wilderness boundary. The trailhead sits on Heart's Content Road (SR-2002), about a half-mile from the Hearts Content Scenic Area. The trail follows a rough path south through second-growth hardwoods before crossing the wilderness boundary, marked by a simple wooden sign. Once inside, the character of the forest changes noticeably: the understory opens, the trees grow larger, and the canopy, mostly hemlock with beech, black cherry, and sugar maple, closes overhead.
Miles 1.5 to 5.0: Into the valley. The trail descends toward Hickory Creek and its main valley. Old-growth hemlock becomes more prominent as you lose elevation. Some of the hemlocks here measure 2 to 3 feet in diameter and stand 80 to 100 feet tall, trees that were already mature when Pennsylvania became a state. The first creek crossings occur in this section, typically easy rock hops in summer but potentially ankle- to knee-deep in spring.
Watch for white-tailed deer, wild turkey, and black bear sign (tracks, scat, claw marks on beech trees) throughout the valley. The wilderness supports one of the healthiest wildlife populations in northwestern Pennsylvania precisely because it lacks road access.
Miles 5.0 to 8.5: The valley traverse. The middle section of the loop follows Hickory Creek and its tributaries through the valley bottom, crossing and recrossing the creek as the drainage narrows and widens. This is the most remote-feeling part of the trail. The forest here is dense and quiet. Navigation requires care at the creek crossings, where the trail can be hard to pick up on the opposite bank. Look for a worn path in the leaf litter and trust your topo map.
The North Country National Scenic Trail intersects the loop near the western edge of the wilderness. The North Country Trail (Kellettville section) can be accessed for longer multi-day routes heading north or south along the 4,800-mile trail.
Miles 8.5 to 12.0: The climb back. The trail climbs out of the valley via a ridge spur, gaining most of its 800 feet of total elevation in the final 3.5 miles. The ascent is gradual rather than steep, this is plateau terrain, not mountain terrain, but the cumulative effect of 12 miles adds up. Take your time on the return climb and stop at the wilderness boundary overlook for a last look at the valley before the trail returns to the trailhead.
When to Hike
May and June bring high creek levels (expect wet crossings), blooming trillium and wild ginger on the forest floor, and the most dramatic hemlock scenes when new growth brightens the canopy. Blackflies can be persistent in May. This is the best season for those who want the wilderness at its most lush.
July and August are quieter. Creek levels drop, crossings become easier, and the full hemlock canopy keeps the valley noticeably cooler than the surrounding plateau. Start early to avoid afternoon heat on the return climb.
September and October offer peak conditions: mild temperatures, no bugs, light crowds, and excellent fall color from the hardwood component of the forest. October beech leaves, papery gold lasting well into November, are a particular Allegheny signature.
November through April: Possible on dry winter days, but the wilderness lacks any maintained facilities, and the remoteness is a genuine safety factor in cold or snowy conditions. Go with a partner and a solid plan.
What to Bring
Many overnight backpackers carry a filter and use the creek as their primary water source inside the wilderness. Treat all water. Navigation tools (downloaded topo map on Gaia GPS, Caltopo, or the USFS paper map) are essential, do not rely on cell service or trail signs inside the wilderness boundary.
Tick season runs May through July in Allegheny. Treat clothing with permethrin and do thorough tick checks after the hike. The USFS recommends full-body checks after any backcountry outing in this region.
Trailhead Access
The trailhead is on SR-2002 (Heart's Content Road), about 8 miles south of Tionesta and accessible via PA-36 south or the Kellettville Road connector. The lot holds 8 to 10 vehicles; additional parking is available on the road shoulder. No restrooms, no water, no signage beyond the wilderness boundary sign.
From Warren, head south on PA-62 and connect to PA-36 south, then look for Heart's Content Road (SR-2002) signs toward Tionesta and the Hickory Creek trailhead. Total drive from Warren is about 45 minutes.
Nearby
The Hearts Content Interpretive Trail (1.2 miles, easy) is half a mile up the road and provides an excellent complement, old-growth context with interpretive signs before entering the wilderness. Review the Leave No Trace seven principles before any wilderness overnight.
