Located at the southern end of the 470-mile-long Blue Ridge Parkway and split in two by the border between Tennessee and North Carolina, the Great Smoky Mountains National Park is a sanctuary in the Appalachian Highlands, preserving the world’s finest examples of virgin deciduous forest. Over 100 varieties of native trees and over 1500 species of flowering plants can be found in this International Biosphere Reserve. The Appalachian Trail follows the boundry between Tennessee and North Carolina for most of its distance through the Park. The park has 180 miles of roads and 800 miles of trails, that cover only a small percentage of the half-million acres of forested wilderness. With half the population of the United States living within a one-day drive of the Smoky Mountains, it is no wonder that it is the most visited national park in America with some 10 million visitors going to the park each year.
