The Alum Cave Trail to Mount LeConte is one of the most celebrated hikes in Great Smoky Mountains National Park, which straddles the North Carolina–Tennessee border. The trailhead is located on Newfound Gap Road (US-441) at the Alum Cave parking area in the Cherokee, NC portion of the park, approximately 45 minutes from Gatlinburg, Tennessee, and 1.5 hours from Asheville, NC.
The trail covers 11 miles roundtrip and gains 2,760 feet in elevation, ascending from the trailhead at approximately 3,840 feet to Mount LeConte's summit at 6,593 feet. The hike typically takes 6 to 8 hours for the round trip at a moderate pace with rest stops.
From the trailhead, the route follows Walker Camp Prong upstream through old-growth hemlock and hardwood forest. The first major landmark is Arch Rock at mile 1.4 — a narrow natural arch formed by a stream cutting through metamorphic rock, which hikers pass through via stone steps. Beyond Arch Rock, the trail steepens and enters a heath bald zone. The Alum Cave Bluffs at mile 2.3 are a striking geological formation — a concave cliff overhang of hornblende gneiss that creates a protected alcove where the air feels noticeably drier than the surrounding forest.
Above the bluffs, the trail grows progressively steeper and more exposed. Cable handholds are installed on two sections of smooth, inclined rock face near the upper portion. Trekking poles are strongly recommended for both the ascent and the knee-heavy descent. The summit area includes LeConte Lodge, the highest guest lodge in the eastern United States, which operates from late March through mid-November with reservations typically required more than a year in advance.
A Great Smoky Mountains National Park Recreation Fee (America the Beautiful Pass accepted, or $5 per day) is required. The Alum Cave parking area fills completely by mid-morning in summer; arrival before 8 am is strongly recommended. Backcountry camping on Mount LeConte requires an advance reservation through the park's backcountry permit system.

Tips for visiting
- Arrive at the Alum Cave parking area no later than 8 am from May through October — the lot fills completely and overflow requires walking an additional mile each way.
- Carry a headlamp for the return if starting late; sunset comes quickly on the forested lower section.
- Trekking poles significantly ease both the steep ascent above the bluffs and the knee-heavy descent.
- Carry at least 2 liters of water; no reliable water sources are accessible without treatment equipment.
- The Great Smoky Mountains Recreation Fee ($5/day) is required — an America the Beautiful Pass covers this.
- Weather changes rapidly at high elevation — pack a rain layer even on clear mornings.
When to visit
The trail is most enjoyable from May through October when the summit is typically snow-free and wildflowers bloom along the lower slopes. Avoid holiday weekends and midsummer Saturdays when the parking lot fills before 8 am; weekday starts in September and October offer the best balance of conditions and crowds.
Accessibility
The Alum Cave Trail is not wheelchair or stroller accessible. The route involves 2,760 feet of elevation gain, stone steps through Arch Rock, and cable handholds on exposed rock sections near the summit. The trailhead parking area has accessible restrooms.
