Most mountain bikers who make the trip to Western North Carolina spend their time in Pisgah Proper or DuPont State Forest. South Mill River quietly sits between those two destinations, consistently overlooked and, in its best form, consistently excellent. The South Mills River trail network in Pisgah National Forest includes 26 trails, multiple route options, river crossings, suspension bridges, and backcountry singletrack that rewards riders willing to put in the work. Recovery from Hurricane Helene is ongoing in this area, and trail conditions are changing regularly. This guide covers what the trail system offers and what to verify before you go.
| IMPORTANT: Hurricane Helene (September 2024) caused significant damage throughout Pisgah National Forest, including the South Mills River area. As of early 2026, Turkey Pen Road (FS 297) has limited access due to ongoing repairs, at least one suspension bridge on the South Mills River Trail was damaged and requires a wet crossing, and Yellow Gap Road is closed between Wolf Ford Horse Camp and North Mills River Campground. Conditions are actively changing. Check the USDA Forest Service Helene Closures page and Pisgah Area SORBA trail status before your visit.

TL;DR
- South Mill River Trail #133 runs 12 miles through Pisgah National Forest with a Difficult rating, primarily because of nine bridgeless river crossings rather than technical climbing.
- As of early 2026, Turkey Pen Road (FS 297) has limited access due to Helene repairs, and at least one suspension bridge on the trail was damaged by the storm. Check current conditions before going.
- Yellow Gap Road (FS 1206) is closed between Wolf Ford Horse Camp and North Mills River Campground, limiting western access.
- Connecting trails including Squirrel Gap, Mullinax, and Buckhorn Gap open up loops ranging from a few hours to a full-day effort.
- Spring and fall are generally the best seasons, but conditions post-Helene add additional variability. Always check Pisgah Area SORBA and the USDA Forest Service Helene Closures page first.
- This is a multi-use trail shared with hikers and horses. Yield to both.
What Is the South Mill River Trail System?
South Mill River Trail #133 is a 12-mile corridor that runs through a steep river valley in the Pisgah Ranger District of Pisgah National Forest, near Brevard and roughly 45 minutes south of Asheville. The trail follows an old railroad grade for much of its length, tracing the South Fork of the Mills River through dense forest. Remnants of old railroad trestles appear at several water crossings along the way.
The trail earns its Difficult rating not from its grade, which is gentle with approximately 650 feet of total elevation change, but from nine bridgeless river crossings in the western half. Between Cantrell Creek and the Turkeypen Gap Trailhead, the trail historically had suspension bridges at river crossings, though Hurricane Helene damaged at least one of those bridges. Riders should plan for wet crossings throughout and verify current bridge status before committing to a route.
The trail is designated multiple-use, meaning hikers, mountain bikers, and equestrian riders share the same corridor. Mountain bikes are prohibited in designated wilderness areas, so pay attention to posted trailhead signage. Per the USDA Forest Service, peak season hours at the Pisgah District Ranger Station run April 1 through November 15, 9 AM to 5 PM daily. The ranger station phone is (828) 877-3265.
Getting to the South Mill River Trailheads
| NOTE: As of the most recent USDA Forest Service updates, Turkey Pen Road (FS 297) has limited access due to ongoing Helene-related repairs. Confirm current road status before planning your trip.Yellow Gap Road (FS 1206) is open from Hwy 276 near Cradle of Forestry to Wolf Ford Horse Camp only. The section from Wolf Ford Horse Camp to North Mills River Campground remains closed. |
Turkeypen Gap Trailhead (Primary Access)
For mountain bikers, Turkeypen Gap is the standard starting point. From Asheville, take NC-280 south toward Brevard. After crossing the Transylvania/Henderson County line, turn left onto Turkeypen Road (FS 297). The USDA Forest Service notes this trailhead has limited parking. The lot fills quickly on weekends during peak season. If the lot is full, you can park at the intersection of Turkeypen Road and NC-280 and ride up to the trailhead.
Do not park in the area reserved for horse trailers. Those spaces are clearly marked and needed for equestrian groups using the network. The trail begins near a kiosk and road gate at the far end of the parking area.
Wolf Ford Road Access (Western End)
The western access uses Yellow Gap Road (FS 1206). From the Pisgah District Ranger Station, head north on US-276 for approximately 10 miles, then turn right on Yellow Gap Road. As of early 2026, Yellow Gap Road is only open from Hwy 276 to the Wolf Ford Horse Camp. The section beyond Wolf Ford Horse Camp toward North Mills River Campground remains closed due to Helene damage. Riders planning to use this western access point should confirm current road status with the Pisgah Ranger District before their trip.
Trail Difficulty Breakdown: What to Actually Expect
The overall Difficult rating for Trail #133 can be misleading if you are expecting sustained technical climbing or gnarly descents. Most of the route rolls along a gentle river-bottom grade that is manageable for intermediate riders. The difficulty comes from the water. Nine bridgeless crossings in the western section mean wet feet regardless of conditions, and depending on season and recent rainfall, those crossings can range from ankle-deep to thigh-deep. The valley position means water temperature stays cold even in summer.
Prior to Hurricane Helene, the eastern section between Cantrell Creek and Turkeypen Gap used suspension bridges to cross the river. As of November 2025, at least the first swinging bridge near the Turkeypen access was confirmed damaged, requiring a wet stream crossing. Pisgah Area SORBA has noted the South Mills River area as cleared of major downed trees, but larger impacts including damaged bridges and erosion remain. Verify bridge status before your ride.

The Best Mountain Biking Routes at South Mill River
Turkeypen Out-and-Back (Introductory Loop)
Starting from Turkeypen Gap and riding out on South Mills River Trail toward Cantrell Creek and back is a good introduction to the area’s character. The trail through this section has historically been wide, well-blazed with white markers, and more manageable than the bridgeless western half. Given Helene’s impact on the first swinging bridge, riders should expect at least one wet crossing from the trailhead side regardless of conditions. Plan for roughly two hours out and back at a moderate pace.
Turkeypen to Squirrel Gap via Mullinax (Intermediate Loop)
This is one of the most consistently recommended routes in the Pisgah Ranger District. Starting at Turkeypen Gap, the route follows South Mills River Trail to the Mullinax connector, then climbs to Squirrel Gap Trail (#147). Squirrel Gap features technical roots, benchcut singletrack, and enough flow to reward riders once they settle into a rhythm. The out-and-back typically takes one to three hours. Expect significant climbing and brief hike-a-bike sections on Squirrel Gap. The starting route description on MTB Project reads: start at Turkeypen Trailhead, take South Mills River Trail to Mullinax to Squirrel, out and back.
Turkeypen to Black Mountain Epic (Advanced Only)
For experienced riders with a full day to spend, the Turkeypen to Black Mountain loop covers approximately 25 miles with over 4,500 feet of elevation gain. The route runs from Turkeypen Gap along Squirrel Gap Trail, transitions to South Mills River Trail, climbs Buckhorn Gap to Black Mountain (#127), and finishes with the descent of Turkeypen Gap Trail back to the parking area. Multiple sections on Black Mountain require carrying or pushing your bike. The payoff is some of the best ridge views in Pisgah National Forest. Per MTB Project, plan for five or more hours and carry sufficient food and water, since most of Turkeypen Gap Trail runs along a dry ridge with no water access.
Bikepacking Overnight Options
South Mills River Trail is one of the more bikepacking-friendly corridors in the Pisgah area. There are established campsites along the route, including a noted site near Wolf Ford approximately four miles from the FS 476 access point. The trail connects to Pink Beds, Black Mountain, Squirrel Gap, and Turkeypen Gap trails, opening multi-day options that stretch well beyond the South Mill River corridor. Given ongoing Helene recovery, dispersed camping conditions in the South Mills River area should be verified with the Pisgah Ranger District before planning overnight routes. Cell service is minimal to nonexistent in the valley.
Hurricane Helene Recovery: What Changed in the South Mills River Area
Hurricane Helene made landfall on September 27, 2024 and moved through Western North Carolina causing what the USDA Forest Service described as one of the worst disasters in the area’s recorded history. Pisgah National Forest sustained moderate-to-catastrophic damage across more than 190,000 acres, and approximately 850 miles of trails were damaged. The South Mills River area was specifically identified by The Pisgah Conservancy as one of the most concentrated areas of damage in the entire Pisgah Ranger District.
As of early 2026, the primary impacts relevant to mountain bikers in the South Mills River area include:
- Turkey Pen Road (FS 297): Limited access due to ongoing repairs. Confirm status before driving to the trailhead.
- Yellow Gap Road (FS 1206): Open only from Hwy 276 to Wolf Ford Horse Camp. The section to North Mills River Campground remains closed.
- Suspension bridge damage: The first swinging bridge on the South Mills River Trail near Turkeypen was confirmed damaged as of November 2025. Wet crossing now required at that location.
- Hazard trees: Downed and standing dead trees remain throughout the area. Always look up before stopping or selecting a campsite.
- Wildfire risk: Dried storm debris elevated wildfire activity in 2025 to levels not seen in a decade. Campfire restrictions may be in effect. Check the USDA Forest Service alerts page before any overnight trip.
Pisgah Area SORBA has been actively working on trail recovery throughout the Pisgah Ranger District. Their trail status page lists South Mills River / Turkey Pen as having been cleared of major downed trees, but notes that larger impacts including landslides, damaged bridges, and erosion issues remain. Checking their trail status page before riding is the best way to get current conditions.

When to Ride: Seasonal Trail Conditions
Spring and fall are generally the best windows for South Mill River. Temperatures are mild, trail conditions are typically more stable, and October and early November offer some of the best riding days of the year in Western North Carolina.
Summer riding is possible and the river crossings can be a genuine benefit in the heat. The deep valley position keeps trail temperatures cooler than exposed ridgeline routes. The trade-off is higher water levels after afternoon thunderstorms. With at least one bridge now requiring a wet crossing due to Helene damage, conditions in the eastern section have changed regardless of season.
Winter riding is technically possible but the cold valley temperatures, more challenging water crossings, and potential for icy or soft trail surfaces make it a limited window. Off-season hours at the Pisgah Ranger District shift to Monday through Friday. Trail access stays open, but services and support are reduced.
Post-Helene, an additional variable is wildfire risk from dried storm debris. Fire restrictions were active in 2025 and may continue into 2026. Always check the USDA Forest Service alerts page (fs.usda.gov/alerts/nfsnc/alerts-notices) for active restrictions before any overnight trip.
What to Bring and How to Prepare
South Mill River is a legitimate backcountry area with limited cell service and trail conditions that can vary significantly. Post-Helene, an added layer of preparation is warranted.
Gear Checklist
- Water shoes or a second pair of shoes — wet crossings are now unavoidable near the Turkeypen trailhead
- Extra socks in a dry bag
- Full hydration pack (water from the river requires treatment)
- Offline navigation via Trailforks or downloaded maps — cell signal is minimal in the valley
- Sufficient food for your planned duration plus reserves
- Basic trail repair kit: multi-tool, spare tube, CO2 or pump, tire plugs
- Layering for valley temperature shifts, especially on longer rides
- Check for active fire restrictions before any overnight trip
Trail Etiquette
South Mills River Trail is multi-use. Bikers yield to both hikers and horses without exception. When encountering horses, stop well off the trail, speak calmly to the rider, and wait until the animals fully pass. When passing hikers, give an auditory heads-up and wait for acknowledgment.
Pisgah Area SORBA maintains much of this trail network and has been central to Helene recovery efforts in the district. If you encounter downed trees, note the trail name, take a GPS coordinate or photo if possible, and submit a report through their trail conditions form. Memberships and donations directly fund the trails you are riding.
South Mill River vs. Other WNC Mountain Biking Areas
Western North Carolina offers several distinct riding areas. Knowing how South Mill River fits in helps you plan the right trip for your skill level and current conditions.
| Area | From Asheville | Character | Best For |
|---|---|---|---|
| Bent Creek | 20 min | Accessible, beginner-to-intermediate | First-time visitors, after-work rides |
| North Mills River | 30 min | Flow-forward with gnar elements, swimming hole | Intermediate riders wanting flow and challenge |
| South Mill River | 45 min | Remote, raw, river crossings, link-up routes | Intermediate-advanced, loop builders, bikepacking |
| Pisgah Proper (Davidson River) | 45 min | Technical, steep, old-school gnar | Advanced riders, technical descents |
