For years, cross-country teams have jogged on the rooted paths and trekked up the grueling hills of KENNESAW MOUNTAIN NATIONAL BATTLEFIELD PARK. The park offers about 17 miles of trails that wind through some of the Civil War battlefields, monuments and earthworks. And theres a spectacular view of Atlanta from the top of the mountain. Though crowded at times, the diverse routes allow beginners and hardcore athletes alike to enjoy the expansive park. The park could get even better if officials decide to limit some of the teams (which can be as large as 100 members) to only certain running times to cut down on the wear and tear of the site. Thatll leave you alone with nature for a good sweat.
