The Great Smoky Mountains National Park spans the border between North Carolina and Tennessee.

The Great Smoky Mountains National Park is located on the border between North Carolina and Tennessee, in the Appalachian Mountains. It is one of the most visited national parks in the United States, known for its stunning mountain views, diverse wildlife, and rich cultural history. The park's unique name comes from the mist and fog that often envelop the mountains, creating a smoky appearance. It is home to a variety of ecosystems, ranging from temperate rainforests to alpine environments, and contains a wealth of plant and animal species, many of which are rare or endangered.
