Savannah, Georgia
Nicknamed the "Forest City" thanks to its abundance of live oak and ample Spanish moss providing shade, Savannah is super romantic by any standard. It has cobblestone streets, cute bed and breakfasts galore, and 21 lush public squares ringed by beautiful old homes, but you can take the romance up another notch by riding a horse-drawn carriage through the historic district. The weather is blissfully temperate in the fall.
