Trail guide
This is a 4.3-mile round-trip out-and-back from Cosby Picnic Area to Hen Wallow Falls, usually about 3½ hours. The walk climbs steadily through forest for nearly two miles, then drops down a short, steep spur to a 90-foot cascade. Expect around 900 feet of climbing and rough, rooty footing; the falls, rather than broad mountain views, are the payoff.
Park in the designated hiker lot at Cosby Picnic Area, then walk about 100 yards back along the entrance road to the signed Gabes Mountain Trail start. A parking tag is required for visits longer than 15 minutes. The nearest restroom is at the picnic area. Pets are not allowed on this trail.
The tread is rocky near the start. A connector to Cosby Campground branches left around the first third of a mile; keep to Gabes Mountain Trail. Several stream crossings and footlogs, including at Rock Creek, come early. Roots become more noticeable as the steady climb continues under the hardwood canopy. At roughly 2.1 miles, watch for the marked sharp left toward Hen Wallow Falls and campsite 34. The longer Gabes Mountain Trail continues beyond this turn, so follow the falls spur rather than walking on.
The short spur descends steeply, and you climb it again on the way back. Hen Wallow Creek starts as a narrow stream at the brink, then splits and fans across a broad rock face at the foot of the 90-foot drop. The base is broken, slick rock, not a broad splash pool; stay on the path instead of scrambling over wet boulders. Water flow can be modest after dry weather. Salamanders are often visible in the pool. From stable ground near the viewing area, frame both the narrow upper cascade and the wider lower fan.
Most of the approach is shaded, with hardwoods, hemlock, rhododendron and ferns rather than long-range views. Rosebay rhododendron may show white or pink blooms in early July. The route was also known as Messer Trail; a few reports describe an old roadbed and stonework remnants among the trees, though its history is not well documented. Look for a quartz-seamed boulder on the falls spur, too.
Lynn Camp Prong Cascades is a separate hike elsewhere in the park, listed at 1.4 miles round trip. It is a much shorter option if the sustained climb to Hen Wallow Falls is more than you want.
