Alum Cave Trail

One of the most iconic hikes in the Great Smoky Mountains National Park, the Alum Cave Trail is a 5-mile route (one way) that begins along Newfound Gap Road and climbs to the summit area of Mount LeConte, connecting near Rainbow Falls Trail. Known for its dramatic scenery and unique geological features, this trail is a favorite for hikers making their first trek to LeConte. From rushing creeks to sweeping mountain views, every mile brings something memorable.
The adventure begins alongside Styx Branch, where the sound of flowing water sets the tone for the climb. About 1.4 miles in, you’ll pass through Arch Rock, a striking black slate formation that towers overhead. Formed during the Ice Age by cycles of freezing and thawing, this natural arch is accessed by a steep staircase that winds directly beneath it. Around the two-mile mark, Inspiration Point rewards hikers with panoramic views across the mountains, especially vibrant in summer when azaleas bloom. From here, you may also spot the Eye of the Needle rock formation and look down into Huggins Hell, a rugged valley best admired from above.
At approximately 2.3 miles, you’ll reach Alum Cave Bluffs, a dramatic overhang that many hikers choose as their turnaround point. This section features about 1,200 feet of elevation gain and tends to be the most crowded portion of the trail. Those who continue beyond the bluffs are treated to increasingly open views and a quieter, more immersive experience. The remaining 2.7 miles to the summit are steeper and rockier, including a challenging staircase near mile 3.8 that replaces an old washed-out switchback. A brief stretch of flatter terrain just past the bluffs offers a welcome break before the final climb begins.
The last mile of Alum Cave Trail delivers some of the most breathtaking views in the Smokies. As the trail hugs the mountainside, expansive vistas unfold to the west, revealing layered ridges stretching to the horizon. On a clear day, you may even catch a glimpse of Clingmans Dome in the distance. The path crosses an old rock slide that practically demands a pause to soak it all in. Just a half mile from LeConte Lodge, hikers round a rocky outcrop before reaching the “Hallelujah Turn,” where the trail levels out and offers a gentle walk to the lodge. It’s a triumphant finish to one of the most scenic hikes in the Smoky Mountains.
