Great Smoky Mountains National Park, located near Gatlinburg, is one of the greatest natural treasures of the USA. This vast sanctuary stretches across the heart of the Appalachian Mountains, on the border between Tennessee and North Carolina. Due to its exceptional value, the park is included on the UNESCO World Heritage list and holds the status of a Biosphere Reserve.
The park gets its name from a unique natural phenomenon—a bluish haze that often blankets the mountain peaks and valleys. This effect is created by the vapors from dense vegetation. The park's territory is famous for its incredible biodiversity: about 130 species of trees and more than 3,500 species of other plants grow here, which is comparable to the flora of all of Europe. The wildlife is also rich, including bears, deer, and many other species.
