Watch FMovies. This film takes you on a journey along the 3,000 miles of streams and rivers in the Great Smoky Mountains National Park. These protected watersheds, which splash and churn from the Smokies' highest mountains to the valleys below, draw thousands of visitors to the park each year. Join filmmaker Gary Wilson and narrator Bill Landry as they explore the waterfalls, aquatic life and trout streams alongside dedicated park employees who work to protect rare and endangered species in the park.
