One of the region's oldest industries, tourism became a more important part of the Appalachian economy in the latter half of the 20th century as mining and manufacturing steadily declined. In 2000-2001, tourism in Appalachia accounted for nearly $30 billion and over 600,000 jobs. The mountain terrain—with its accompanying scenery and outdoor recreational opportunities—provide the region's primary attractions. The region is home to one of the world's most well-known hiking trails (the Appalachian Trail), the nation's most-visited national park (the Great Smoky Mountains National Park), and the nation's most visited national parkway (the Blue Ridge Parkway). The craft industry, including the teaching, selling, and display or demonstration of regional crafts, also accounts for an important part of the Appalachian economy, bringing (for example) over $100 million annually to the economy of western North Carolina and over $80 million to the economy of West Virginia. Important heritage tourism attractions in the region include the Biltmore Estate and the Eastern Band of the Cherokee reservation in North Carolina, Cades Cove in Tennessee, and Harpers Ferry in West Virginia. Important theme parks include Dollywood and Ghost Town Village, both on the periphery of the Great Smoky Mountains.
