1 Best Sight in Gatlinburg, Tennessee

This 1.4-million-gallon saltwater aquarium highlights the wonders of the underwater world. You can get up close and personal with a penguin, pet a stingray, share space with 12-foot-long sharks swimming in overhead tunnels, and stick around for the dive and feeding shows. Groups that include 10 or more children can schedule a sleepover with the sharks!
