Challenging

This is a stout Appalachian Trail climb from the Fontana Dam area up Twentymile Ridge to the historic, 60-foot Shuckstack Fire Tower. If you like your payoff big and your workout bigger, this one delivers: a classic Smokies ascent capped by true 360-degree views across Fontana Lake to the Unicoi, Snowbird, Nantahala, Blue Ridge, and deep into the Smokies.
Expect roughly 9.0–9.2 miles total if you start at the Fontana Dam Visitor Center and walk across the dam to the AT trailhead. If you begin on the north side of the dam at the AT trailhead, it’s about 6.8–7.0 miles total. Either way, you’ll gain about 2,200–2,450 feet, with more than 2,000 feet of that punched into the first 3.5 miles. Most hikers take about 3.5–5 hours, with around 5 hours common from the visitor center.
The route wastes no time—there’s essentially no warm-up as the AT tilts uphill right away. As you gain the ridge, you’ll snag intermittent peeks of Fontana Lake through the trees (best in late fall and winter). Near a shallow gap between Shuckstack and Little Shuckstack the grade eases briefly, then climbs again past a rocky break/old slide with south-facing views. The short, steep spur to the tower is marked with a white “T” off a three-way junction on Twentymile Ridge. At the top, you’ll find the steel lookout (built in 1934) and the ruins of the old watchman’s cabin (chimney and cistern). The tower’s six flights/78 steps lead to a compact cab with panoramic views that make the grind worth it.
Underfoot it’s classic AT: natural tread with dirt, roots, and some rocky spots, plus a few ridge outcrops. Summer can be overgrown near the top. The summit area includes outcrops of Precambrian Ocoee Supergroup sandstone—part of what gives the tower those far-reaching sightlines.
Clear days are king for the long views. Late fall and winter offer the most open lake vistas through leafless hardwoods and can feel downright magical after a snowfall, but expect cold temps and possible ice on the tower stairs. Summer brings lush foliage, heat, bugs, and ticks; long sleeves and repellent help. Aim for early starts to beat heat and ensure you have time for the tower and breaks. The Fontana area sees far fewer people than the park’s central hubs, so solitude is common outside peak weekends.
For a bigger or different outing, you can approach Shuckstack from the Twentymile side (via Twentymile Trail or a longer loop with Twentymile Loop and Wolf Ridge). If you decide to skip the spur, the AT continues along the ridge toward the Lost Cove and Twentymile junctions.
Park at the Fontana Dam Visitor Center; walk across the dam to the Appalachian Trail on the north side. No vehicle access across the dam.
Sustained climb over 2,000 ft in 3.5 miles; aging, narrow fire tower with missing railings and sway; icy steps in winter; summer overgrowth, bees, and ticks.
