Thunderhead Mountain is a mountain in the west-central part of the Great Smoky Mountains, located in the Southeastern United States. Rising along the border between Tennessee and North Carolina, the mountain dominates the Western Smokies. The Appalachian Trail crosses its summit, making it a popular hiking destination. Rocky Top, a knob on the western part of the mountain's summit ridge, shares its name with a popular Tennessee state song.
Thunderhead rises approximately 3,500 feet (1,100 m) above its northern base at Little River and approximately 3,000 feet (910 m) above its southern base at Bone Valley. The mountain consists of three peaks, the lowest being Rocky Top at 5,440 feet (1,660 m) above sea level and the easternmost being the highest at 5,527 feet (1,685 m) above sea level. Thunderhead is the highest point in Blount County, Tennessee and the highest point on the Appalachian Trail coming from the south until the trail ascends Silers Bald (5,607 ft) some 10 miles (16 km) to the east.
