TrailKnob Mountain – Jeremys Run
6-mile circuit, 1,303ft gain, moderately strenuous. Jeremys Run's picturesque stream through wilderness—expect steep grades and stream crossings. 7.5 hours.

This 5.1-mile round trip climbs 1,291 feet to Shenandoah's highest waterfall—a dramatic 93-foot cascade that roars in spring. Moderately strenuous with exposed switchbacks and relentless uphill grind. The payoff is real: a wilderness waterfall and creek crossings in federally protected Wilderness, but only if you bring grit and water. Expect 4 hours of sustained climbing on rocky terrain.
Lung-buster. Relentless uphill. Suits fit hikers only.
Shenandoah's highest waterfall—93 feet of cascading force when water flows in spring; federally designated Wilderness setting.
• The upper falls viewpoint at Mile 2.2 is a solid turn-around for weaker hikers (saves 1 mile and 500 feet gain). • Waterfall is a trickle in summer—spring (May) or post-rain visits are mandatory for roar. • Mathews Arm lot is tiny; arrive before 8 AM or use Mile 21 alternative trailhead. • Outcrop closures are enforced by rangers; stay on blazes. • Filter water at the base of waterfall if you run low—many hikers do.
Spring (late April–May) for waterfall flow and wildflowers; October for fall color and fewer biting insects.
Challenging for children under 10 unless extremely fit and experienced hikers. Teens 14+ with solid aerobic fitness can handle it. Slippery rocks demand hand-holding on steep sections. Waterfall area has unprotected drop-offs—close supervision essential.
Hikers consistently report the 1,291-foot elevation gain is brutal—but the waterfall is unforgettable in spring. Fit solo hikers and experienced groups praise the Wilderness solitude; families with young kids often bail at the upper falls (Mile 2.2). The scenic payoff and ecosystem rarity make the grit worth it for the right hiker.
None required. Wilderness hiking is unrestricted; no overnight permits needed for day hikes.
If Mathews Arm Campground is closed, park at Mile 21 on Skyline Drive and take Appalachian Trail south to Tuscarora-Overall Run Trail junction (adds 1 mile to hike).
Steep rocky switchbacks with 1,291 feet gain over 2.5 miles. Algae and water make rocks treacherous, especially after rain. Loose scree on upper sections increases twisted ankle risk. Waterfall viewing area has protective closures to prevent ecosystem trampling—violations are ticketed. High sun exposure on switchbacks increases dehydration risk; water depletion is common on descent.
Steep, rooty, rocky terrain with no paved sections. Waterfall viewing involves scrambling on unstable ground. Not ADA accessible.

It's moderately strenuous, not expert-only. If you've completed 5+ mile hikes with 1,000+ feet gain, you can do it. The payoff earns the pain. Weaker hikers should bail at Mile 2.2 (upper falls).
Not always. Spring (May) and 48 hours after heavy rain guarantee cascade. Summer (July–August) is often a trickle. Check stream flow reports before committing—a dry waterfall isn't worth 4 hours of suffering.
Yes, but risky. The trail is popular and well-marked, but no cell service means solo hikers have limited backup. Bring a whistle, tell someone your plan, and turn back if you feel unsafe.
Trekking poles reduce descent impact on knees by 25%—highly recommended. Proper boots with ankle support are non-negotiable on rocky terrain. Gaiters prevent debris. Map and compass or GPS are essential for Wilderness navigation. All useful; boots and map are critical.
NPS says 4 hours. Expect 4–5 hours if fit and stop for photos. Casual hikers: 5–6 hours or turn back at Mile 2.2 (upper falls). Don't underestimate descent time—tired legs on rocky downhill is the injury zone.
Black bears exist but rarely encounter hikers; make noise to avoid surprise. Mountain lions are extremely rare. Snakes are a non-issue at Shenandoah's elevation. Mosquitoes and biting flies (June–August) are the real threat—insect repellent is essential.
