Editor's note: The Smokies are some of the world’s oldest mountains, formed between 200-300 million years ago. Compared to the young, brash Rockies, the Smokies feel worn-down and gentle, welcoming and soothing. The park is enormous, so you can do the touristy bit or get away from it all, and we’ve captured a diversity of options in this cool collection.
