The Chickamauga National Battlefield is the largest federal civil war battlefield in the nation. It boasts over 5200 acres. Hike in the mountains and see waterfalls and beautiful vistas with a few thousand foot drops. If you time it right, you will be able to go to one of the many festivals that are either right here in Chickamauga, or in neighboring small towns. And of course there is Chattanooga. Known for its very very family friendly down town complete with parks that have waterfalls and streams that the kids can jump right into on a hot day and have a great time, and so far everything that I have mentioned is FREE.
