Gatlinburg, a mountain town in eastern Tennessee, is known as a gateway to the roughly 520,000-acre Great Smoky Mountains National Park. Many of its key attractions offer sweeping views of the neighboring park, including the 407-ft. Space Needle observation tower and the Sky Lift, a 2.1-mile aerial cable car that journeys from Downtown to the popular amusement park and ski resort Ober Gatlinburg.
