1. Kennesaw Mountain National Battlefield Park, Georgia
Get a taste of history before you hit the trails at this Civil War battlefield turned national park. Head to the Visitor’s Center to pick up a map with detailed distances and times for four different hiking options, as well as how many calories you’ll burn on each trail (but if you’re not into those, don’t worry—there are plenty more paths to choose from). We’d recommend starting with Pigeon Hill Trail, which has a steeper grade, so you’ll burn more calories in less time. The 5.4 mile trip will only take you about 2 hours. Make sure to keep an eye out for cannons and trenches, reminders of the battle fought on the mountain.
