Grotto Falls, Roaring Fork Motor Nature Trail, on Tennessee side of Great Smoky Mountains National Park, southeastern USA.
Grotto Falls is a hike of 2.6 miles round trip from the Roaring Fork Motor Nature Trail, on the Tennessee side of Great Smoky Mountains National Park, in southeastern USA. The source of Roaring Fork is located nearly 5,000 feet (1,500 m) up along the northern slopes of Mount Le Conte, where several small springs converge. From its source, Roaring Fork drops 2,500 feet (760 m) over just two miles (3 km), spilling over Grotto Falls. The mouth of the Roaring Fork empties into the West Prong of the Little Pigeon River in Gatlinburg, TN. The Roaring Fork valley is underlain by Precambrian Class II sandstone of the Ocoee Supergroup, a rock formation formed from ancient ocean sediments nearly a billion years ago, as in most of the Smokies.Add to Cart Add to Lightbox Download
