Great Smoky Mountains National Park Keychain

The great forests that cloak these geologically ancient mountains on the North Carolina-Tennessee border breathe organic compounds into the moist Smoky Mountain air, creating the distinctive bluish mist that inspired the naming of this park. Also known for its mountain hollows, waterfalls, historic buildings, mountain culture and plentiful population of black bears, the nation’s most-visited national park is one of the most biodiverse, hosting more than 100 tree species and thousands of plants.
