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.

Old Rag Circuit is the most popular hike in Shenandoah—and for good reason: a 360-degree summit view that makes you feel on top of the world. This 9.4-mile circuit is brutally strenuous with 2,348 feet of elevation gain and demands serious fitness, technical rock scrambling, and relentless focus. You'll confront exposed boulders, steep pitches, and the mental grind of a 7.5-hour push. If you're fit, committed, and have planned properly, the views and sense of accomplishment are worth every gasping breath.
Lung buster - relentless elevation gain and technical rock scrambling
360-degree summit panorama is the reward—the single most high point in Shenandoah. The rock scramble (miles 5–6) delivers adrenaline and technical moves. Ridge views stretch across valleys and ridgelines to the horizon with sky on all sides.
• The false summit at mile 6 is demoralizing—real summit is higher; keep pushing past the frustration • Descend Saddle Trail (not Ridge Trail) to spare your knees on the long descent • Park overflow fills at outlying areas; arrive before 6am on summer weekends • Scramble is easier when done clockwise (Ridge Trail up, Saddle Trail down); counterclockwise inverts the crux into your descent • Bring a headlamp even on daytime hikes; if delays occur, you may finish after dark
March through November; spring (April-May) and fall (September-October) offer stable weather and fewer crowds than summer
Only for experienced young hikers (teens+) with excellent fitness and scrambling comfort. Loose rocks and steep drop-offs require constant hand-holding and focus from adults. Younger children will struggle and may panic on exposed sections. Not suitable for families seeking an easy outing.
Hikers rave about the 360-degree summit and scramble adrenaline, but they don't hide the brutal elevation gain, dry conditions, and technical footwork. Most say it's the single most rewarding hike in Shenandoah—if you're fit enough to earn it. Fit hikers complete it proud; unfit ones regret starting and question their preparation.
Day-use ticket ($1) required March 1–November 30. Book in advance at nps.gov/shen/planyourvisit/faqs-oldrag.htm. Also requires standard Park entrance pass ($30, valid 7 days).

Loose, uneven rocks require careful foot placement and hand use. Exposed ridge offers zero shelter from lightning—descend immediately if storms approach. The scramble can disorient hikers when blazes fade on rock. Dehydration is a real threat: dry trail, high sun exposure, 7+ hours of sustained effort, and limited water stops. Drop-offs on the ridge demand respect and focus.
Rooty, steep, with exposed scrambles and uneven boulders - not ADA accessible. Does not meet ADA accessibility guidelines.
Only for experienced young hikers (teens+) with excellent fitness and scrambling comfort. Loose rocks and steep drop-offs require constant hand-holding and focus from adults. Younger children will struggle and may panic on exposed sections. Not suitable for families seeking an easy outing.

Yes. Very Strenuous is not marketing fluff. The 2,348 feet of gain packed into 9.4 miles is relentless. If you can't hike 4+ hours uphill at a steady pace on rocky terrain, this will break you. Train first.
Not recommended without experience. If you twist an ankle on the scramble or hit altitude sickness, you're isolated and cell service is unreliable. Bring at least one partner who knows how to navigate and help. Solo hiking here is reckless.
Descend immediately. The exposed ridge is a lightning magnet with zero shelter. No rocks to hide under—you are the tallest object. Check the weather forecast before 7am; turn back if storms are predicted for noon onward.
Trekking poles are essential for the descent—they save your knees and prevent slips on loose rock. Bring 3+ liters of water, sunscreen, a hat, and a map. Sturdy hiking boots (not sneakers) are mandatory. Rock scramble skills help but aren't required—move slowly and test every hold.
It's exposed with drop-offs, so yes—respect it. The scramble itself isn't technical climbing; it's boulder hopping with exposure. Slow down, use your hands, and commit to each move. Fear is healthy. Recklessness kills.
Only if visibility is good. Summer afternoons bring clouds; arrive early. Winter can bring rime ice and poor views. Fog rolls in without warning. Check weather and visibility reports. On a clear day, the 360° view is unmatched; on a cloudy day, it's a slog.
No. Build fitness on easier Shenandoah trails (Lewis Falls, Limberlost, Hawksbill) first. Old Rag is a bucket-list goal, not an entry hike. Respect the mountain—it humbles the unprepared.
