The Great Smoky Mountains are a subrange of the much larger Appalachian Mountains.
The Appalachians stretch over 1,500 miles from Newfoundland to Alabama and feature the breathtaking Appalachian trail, while the Smokies span about 70 miles along the Tennessee-North Carolina border.
The Smokies are known for their lush forests, diverse plant and animal life, and characteristic 'smoky' haze.
