Mountain City was home to Chet Atkins during his adolescence, as a result of a near fatal asthma attack that prompted him to leave his home in Tennessee and live with his father. It was during this time that his interest in music, especially guitar, was honed.
Mountain City is also home to one of the most popular teenage camps, Camp Blue Ridge. Camp Blue Ridge is a Jewish-based camp for adolescents, located in the beautiful Blue Ridge mountains. Teens attend Camp Blue Ridge during the summer months of June–August, and come from populated southern states, such as Florida and Georgia, but there have been a lot of campers from far away places, and various other countries.
