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.

The Doyles River Trail is a moderate 3.3-mile round-trip that rewards grit with two separate waterfalls and mountain stream scenery. You'll gain 1,189 feet crossing the blue-blazed route through cool forest, with a mandatory stream crossing that tests footing. The trail is well-marked with posts showing Upper and Lower Doyles River Falls locations. Plan 2.5 hours of sustained climbing if you're fit; this is not a casual stroll, but the waterfall payoff justifies the elevation cost.
Moderate—relentless elevation gain, stream crossing, technical footing on descent.
The two Doyles River Falls—upper and lower cascades—are marked with trail posts. The stream crossings offer relief on hot days and test your balance on slippery rocks.
• The second (lower) waterfall is the more impressive of the two; don't turn back after seeing the first. • Arrive by 8 AM on weekends or plan a weekday hike. The parking lot fills fast and overflow has nowhere to go. • Late summer (August-September) offers lower stream levels and fewer bugs—ideal for the crossing. • The descent is harder on knees than the ascent; take it slow and use trekking poles.
May through October. Spring offers cool temps and water flow; summer brings crowds; fall has low humidity and clear views.
Suitable for older children (8+) with solid hiking experience. Stream crossing requires hand-holding for younger kids. Slippery rocks and steep sections demand constant adult supervision. Not recommended for toddlers or unfit children. Dogs acceptable on-leash but may struggle with scrambling sections.
Hikers praise the waterfall payoff and cool forest shade but warn that the stream crossing and steep descent demand respect. Most say the 1,189-foot gain is steeper than expected, but the dual waterfalls justify the effort for fit hikers.
No permit required. Entrance fee to Shenandoah National Park applies.
The stream crossing at Mile 1.5 is the primary hazard—water moves fast after rain and rocks are extremely slippery. Steep descent on rocky terrain with limited handholds. Exposed roots and loose rocks cause twisted ankles. Narrow tread on the descent with cliff edges nearby—falls are possible.
Not ADA-accessible. Rooty, steep sections, stream crossing, and rocky terrain prohibit wheelchair or assisted mobility access.

Only if the water is high from rain. After rain, water moves fast and rocks are treacherous. Choose a low-water day or use trekking poles for balance. Wait until late summer for the safest crossing.
Yes, if you're fit and carry a satellite communicator. Cell service is unreliable. Tell someone your plan and expected return time. The trail is well-marked.
Trekking poles are essential for the stream crossing and knee relief on descent. Waterproof boots recommended. Bring 2L+ water, a map, and a headlamp. Microspikes if snow is present.
You should comfortably hike 3-4 miles with 2,000 feet of elevation gain on another trail first. If that's a stretch, this will hurt. The descent is as hard as the ascent.
Black bears are present but rarely seen on this trail. Make noise, don't run if you see one, and store food in your vehicle. No bear canister required for day hikes.
Moderate crowds on weekends and summer. Solitude available on weekday mornings before 9 AM. July-August is peak season; expect people.
Yes, most of the day on weekends, especially near the falls. Weekday mornings are quieter.
