What was once a black, smoked covered coal city is now booming with arts and culture. Chattanooga, possibly most famously known for the Chattanooga Choo-Choo, is a small city located on the border of Tennessee and Georgia. Enjoy the green space of Coolidge Park and make your way across the Tennessee River to the famous Chattanooga Aquarium, or head to the weekend market full of local food and craft vendors.
