They got a pretty neat national park nearby. Take a day and go to Cades Cove. Hiking, biking, horseback riding, wildlife viewing (elk, deer, black bear, etc.). Take the primitive road out of Cade's Cove over the mountains to Townsend and rent a tube and float down the river. There are several swimming holes to stop at between the park entrance and Cade's Cove. And don't pet the bears. They'll eat you. All this will eat up a day.
