Twentymile Trail

Overview

If you like your Smokies hikes with steady climbing, cold creek air, and a big-view bonus at the top, the Twentymile Trail delivers. From Twentymile Ranger Station, it runs 5.0 miles one way to the Appalachian Trail (10.0 miles total out-and-back), gaining about 2,300 feet with the final 1.9 miles being the steepest. Much of the lower trail follows an old railroad grade along Twentymile Creek—wide, well-defined, and punctuated by footlogs and bridges—before transitioning into a tougher grind toward the AT junction near Shuckstack.

What You’ll See

The first miles are all about water: constant creek company, small cascades, and lush, shaded forest. A short spur near the start detours to Twentymile Creek Cascades—a worthwhile warm-up if you want a quick payoff early. Around 0.5 miles in, you meet Wolf Ridge Trail; farther up, expect Backcountry Campsite #93 at 1.8 miles and a key junction at Proctor Field Gap (3.1 miles) with Long Hungry Ridge and the Twentymile Loop connector. Hit the AT at 5.0 miles; from there, a short spur leads to the historic Shuckstack fire tower for sweeping Smokies-and-Fontana views on a clear day.

Difficulty and Trail Character

Don’t let the gentle start fool you—the last stretch is a stout climb. Footlogs aid multiple crossings, but after heavy rain some can be washed out, which can mean wet feet. Expect occasional downed trees and roots. This is a classic Smokies “work for it” trail: not technical, just sustained and honest. Solitude is a real perk here compared to busier park headliners.

Logistics

Trailhead access is at Twentymile Ranger Station near Robbinsville, where the small lot fills on busy days. The access road can be rough for low-clearance vehicles. Parking is near the entrance or bunkhouse, then you’ll walk around a gate to start. A parking tag is required when parking in the park.

Tips and Alternatives

• Water after storms runs high—plan footwear you’re happy to wade in if a footlog is out.
• If you want a shorter, mellower outing, stop at the cascades near the start. Prefer a moderate half-day loop? Link Twentymile Trail with Wolf Ridge and the Twentymile Loop connector for a 7.7–7.9 mile circuit with about 1,381 feet of gain.
• No dogs on this trail (or most backcountry trails in the park).

Best Time to Hike

Spring through late fall is prime. Spring brings wildflowers and lively flow over the cascades; summer offers deep shade but aim for an early start to beat heat and afternoon storms; fall adds color. Weekdays are quieter, and mornings give you cooler temps, better light in the creek corridor, and a better shot at a tower view before haze builds.
