The West Prong Little Pigeon River is one of the best trout streams in Great Smoky Mountains National Park, flowing along Highway 441 from near the Chimney Top Trailhead to its exit from the park at Gatlinburg, Tennessee. This medium to large-sized stream contains primarily rainbow trout in the lower and middle sections, with brook trout appearing in the upper portions and headwaters. The river forms from the confluence of Walkers Camp Prong and Road Prong at the Chimney Trail crossing. Characterized by riffles, runs, and pools in its lower sections, the stream transitions to more challenging terrain with huge boulders and deep pools as it moves upstream. Sections of the river support wild trout populations alongside stocked fish. The West Prong Little Pigeon River also harbors several species of phreatic snails, making it an ecologically diverse aquatic ecosystem in the region.
