Alum Cave Trail is one of the most popular and rewarding hikes in Great Smoky Mountains National Park. This 5-mile roundtrip trail to Alum Cave Bluffs offers diverse terrain, fascinating geology, and stunning mountain views that draw hikers from around the world. The trail begins along Alum Cave Creek, crossing log bridges and passing through old-growth forest before reaching the dramatic Arch Rock, a natural tunnel carved through the mountain by centuries of water erosion.
Beyond Arch Rock, the trail opens to sweeping views of Anakeesta Ridge and the surrounding peaks. The highlight is Alum Cave Bluff, an impressive 80-foot concave overhang that sheltered Confederate soldiers who mined the bluff for saltpeter during the Civil War. The bluff's mineral-stained walls and the cool air beneath the overhang make it a memorable rest stop. For ambitious hikers, the trail continues another 2.7 miles beyond the bluffs to the summit of Mount LeConte, the third highest peak in the Smokies.
The trail gains approximately 1,300 feet in elevation, making it moderate to strenuous depending on your fitness level. The trailhead is located on Newfound Gap Road, about 15 minutes from the Sugarlands Visitor Center. Parking fills early on busy days, so arriving before 8 a.m. is strongly recommended. Winter visits can reveal spectacular icicle formations along the bluff face, adding a seasonal dimension to this already remarkable hike.
