Stumphouse Tunnel Railroad Grade Trail
1850s railroad grade to unfinished mountain tunnel.
The old Blue Ridge Railroad grade climbs steadily through Issaqueena Falls gorge toward the infamous Stumphouse Tunnel, where Irish immigrant workers blasted into solid granite from 1856 until the Civil War ended the project. The tunnel portal, carved 1,600 feet into Stumphouse Mountain, remains exactly as abandoned in 1859 — a testament to antebellum railroad ambitions that never connected Charleston to the Midwest. The approach follows original hand-laid stone retaining walls and crosses Cane Creek on the remnants of a cut-stone bridge arch.
Easy trail suitable for high-clearance vehicles, though the final approach to the tunnel requires parking and a short hike. Winter ice can form inside the tunnel, which maintains a constant 50-degree temperature year-round. The railroad grade is accessible year-round with no permits required. Primitive camping is available at nearby Oconee State Park. It’s a fascinating glimpse into South Carolina’s failed railroad dreams, where you can walk into a mountain and touch pre-Civil War tool marks on tunnel walls.

Frequently asked questions
Can a stock SUV or crossover handle this trail?
A high-clearance vehicle is recommended — the gravel surface is generally manageable, but low-clearance cars risk scraping on rougher sections. A stock 4Runner, Wrangler, or similar rig will have zero issues.
Is Stumphouse Tunnel Trail accessible year-round?
Yes, it's open year-round. Winter can bring wet, slick gravel and occasional ice on shaded sections, so approach with some caution between December and February.
Do I need a permit or pass to drive this trail?
No permit is required. It falls under Sumter National Forest, so standard forest road rules apply — no fees, no passes needed for the drive itself.
What's the hardest section of this trail?
There's nothing technically demanding here — it's an easy gravel forest road. The 380-foot elevation gain is gradual, and the biggest challenge is watching for soft shoulders after heavy rain.
Is there any cell service on the trail, and can I camp near the tunnel?
Cell service is nonexistent on the trail, so download your maps offline before you leave Walhalla. Dispersed camping on Sumter National Forest land is allowed in designated areas, but the tunnel site itself is a day-use area — don't plan to sleep at the trailhead.
