The Twentymile Loop Trail is a demanding 13-mile circuit located in the Great Smoky Mountains National Park near Pigeon Forge, Tennessee. This trail combines sections of the Twentymile Trail to create a full loop that takes hikers through varied terrain including thick forests, rushing streams, and open ridges. It is favored by experienced hikers seeking a longer and more isolated trek away from the busiest parts of the park. The trail offers a quiet, immersive experience in the heart of the Smokies.
The Great Smoky Mountains formed over 200 million years ago, shaped by ancient geological forces that created the park's characteristic rounded peaks and rich biodiversity. Twentymile Loop runs through an area once inhabited by Cherokee people, who valued these mountains for their abundant resources. The trail also follows remnants of old logging roads, a reminder of the region’s early 20th-century timber industry before the park’s establishment in 1934. This blend of natural beauty and historical context adds depth to the hike.
