Gatlinburg is a mountain resort city in Sevier County, Tennessee, United States. As of the 2000 U.S. Census, Gatlinburg had a population of 3,828. The city is a popular vacation resort, as it rests on the border of the Great Smoky Mountains National Park along U.S. Highway 441, which connects Gatlinburg to Cherokee, North Carolina through the national park. Gatlinburg is hemmed in on all sides by high ridges, with the Le Conte and Sugarland Mountain massifs rising to the south, Cove Mountain to the west, Big Ridge to the northeast, and Grapeyard Ridge to the east. The main watershed is the West Fork of the Little Pigeon River, which flows from its source on the slopes of Mount Collins to its junction with the Little Pigeon at Sevierville.
