The name Kennesaw comes from the Cherokee word gah-nee-sah, which means burial ground. Fitting, since the Battle of Kennesaw Mountain ended the lives of an estimated 4,000 men in the summer of 1864, with 62,000 others either captured or injured. Nowadays, the site of some of the heaviest fighting of the Civil Wars Atlanta Campaign has become the 2,888-acre KENNESAW MOUNTAIN NATIONAL BATTLEFIELD PARK. Trek to this well-preserved site for a first-hand history lesson more interesting than anything they told you in class. There are more than 17 miles of trails for walking, and a 1.4-mile hike to the summit. Just dont try to make off with any historical mementos of your own. Doing so could cost you $100,000 or even land you in jail. Plus, its just plain disrespectful.
