Middle Prong Trail

Middle Prong is an 8.2-mile out-and-back from the trailhead at the end of Upper Tremont Road. It follows the stream on a former railroad grade, passes several cascades, then gets rougher as it climbs toward the headwaters. Allow about five hours for the full trail with stops. The line in your map follows the established trail to its end and back; a short, unmarked side path near the far end leads to Indian Flats Falls and adds a little distance.

If you want a shorter outing, the first stretch to Lynn Camp Prong Cascades is about 1.4 miles round trip. That lower walk is wide and mostly gentle. It is a very different commitment from the full trail.

The trail starts at the meeting of Lynn Camp Prong and Thunderhead Prong, then crosses a metal footbridge and settles beside the water. Much of this lower section is an old, broad railroad grade, so the path is easier underfoot than the miles ahead. Around four-tenths of a mile, Lower Lynn Camp Falls spills over a series of low rock steps; a clearer view opens a little farther along. Lynn Camp Falls comes next, around seven-tenths of a mile from the start. The stream, boulders, and short falls make this stretch worthwhile even if you turn around early.

The path stays beside the prong through a wooded corridor, with short rocky sidetracks to smaller cascades. At about 2.5 miles, Panther Creek Trail branches toward Jakes Gap; keep to Middle Prong for the longer hike. The grade becomes rougher beyond this junction, and the walk feels less like a stroll than the first mile. Around 3.1 miles, a chimney and other old remnants recall the logging and settlement that once filled this valley.

Near 3.7 miles, the trail crosses Indian Flats Prong on a footbridge. Two smaller creek crossings come before it and lack bridges, so wet or high water can make the stepping stones harder to manage. Beyond the bridge, the path climbs in switchbacks toward its end. Expect more uneven ground here, and save time and energy for the return trip.

Just over four miles in, a short, unmarked right-hand spur leads toward Indian Flats Falls. The falls drop in three tiers for roughly 60 feet. The upper cascade is easiest to see; rhododendron and broken terrain hide much of the lower section. Rocks beside the water are slick, so enjoy the falls from a stable spot instead of climbing around for a closer view. The spur is not part of the 8.2-mile mapped trail distance, and it is easy to walk past if you are expecting a signed junction.

The drive to the trailhead follows unpaved Upper Tremont Road, which is maintained. A parking tag is required if you leave your car for more than 15 minutes. There is no restroom listed at the remote trailhead; the nearest listed restroom is at the Great Smokies Welcome Center in Townsend. Dogs are not allowed on this park trail. For a much shorter outing, use the cascades as your turnaround rather than treating the full route as a casual waterfall walk.
