Alum Cave Trail, Hiking trail in Great Smoky Mountains National Park, Tennessee, United States.
The 4.4-mile round trip trail climbs 1,125 feet through old-growth forest, passing natural formations including black slate Arch Rock and sandstone cliffs.
The area served as a mining site for alum and Epsom salts from 1838 until the mid-1840s, with resumed operations during the American Civil War.
Gracie McNichol, who hiked the trail on her 92nd birthday, received recognition through the naming of Gracie's Pulpit, a notable vista point.
Two parking lots at the trailhead provide access from Newfound Gap Road, with early arrival recommended during weekends and tourist seasons for space.
The trail features the Eye of the Needle, a natural opening in Little Duck Hawk Ridge visible from Inspiration Point at two miles from the trailhead.
