This is one of the busiest trails in the park. It is a moderate trail with a few difficult areas. Along the trail you will see the Arch Rock, Alum Cave Bluffs and dramatic landslide scars on the flanks of the mountain and excellent views of the Little Pigeon River Gorge. Minerals have been found at Alum Cave Bluffs that are not known to exist anywhere else in the world! Chimney Tops is a strenuous 4-mile round trip hike. It is a popular trail because of the views. It is a steady uphill climb and can be hazardous at the top. If the parking lot is full when you arrive, you may want to try the trail another time. The trail becomes very narrow at the top that can be dangerous with a lot of hikers on the trail. Remember the hikers motto: Leave only footprints Take only Pictures Kill only time
