Carolina Sandhills National Wildlife Refuge Borrow Pit Technical Loop
Deep sand technical challenge in the Sandhills.
The Borrow Pit Loop takes you deep into the Carolina Sandhills’ most challenging terrain, following abandoned roads used during the refuge’s construction in the 1930s. These routes cut through 40-foot sand dunes and longleaf pine savannas where the Civilian Conservation Corps once extracted sand for dam construction. The trail includes steep sand climbs at Pool 5 and technical descents into pond bottoms that’ll have you aired down and in 4-Low throughout the 14-mile circuit.
Expert-level difficulty due to deep sand and steep grades that catch experienced drivers off-guard. You’ll need aggressive tread, proper airing down technique, and recovery gear — getting buried here means a long walk for help. Fall through early spring offers the best conditions when sand is more compact. Special Use Permit required from refuge headquarters, and the route is only open October through March to protect nesting wildlife. No camping allowed, but the technical challenges and rare ecosystem make it worth the day trip for serious sand runners.

Frequently asked questions
Can a stock 4Runner or Jeep Wrangler handle this trail?
Not without modifications. Stock rigs will get buried — deep, loose sand demands aggressive mud-terrain or sand-specific tires, and you'll want to air down to 10-15 PSI. Lockers or a limited-slip rear axle are strongly advised; recovery gear (boards, hi-lift, snatch strap) is non-negotiable.
When is the best time to run this trail and are there seasonal closures?
October through March is the sweet spot — cooler temps mean firmer sand and far fewer bugs. Summer heat turns the sand even looser and makes a stuck situation genuinely dangerous; portions of the refuge may also close seasonally for wildlife management, so check with US Fish and Wildlife Service before you go.
Do I need a permit to drive the Borrow Pit Technical Loop?
Yes — this trail runs through Carolina Sandhills National Wildlife Refuge, managed by US Fish and Wildlife Service, and a permit is required. Contact the refuge directly at fws.gov/refuge/carolina-sandhills to confirm current access rules, as permitted areas and conditions can change.
What's the hardest section and what should I actually expect?
The abandoned borrow pit construction roads are the crux — you're navigating unmaintained sand tracks that can shift dramatically between visits, with no berms or traction aids. Expect extended sections of wheel-deep loose sand where momentum is your only friend, and plan for at least one recovery per group on a first run.
Is there any cell service on the trail, and how far is the nearest gas from the trailhead?
Cell service is completely absent for the entire 14 miles — download offline maps and share your trip plan before you leave. McBee, SC is the closest town for fuel, roughly 10 miles from the trailhead, so top off there; there's nothing closer once you're in the refuge.
