Stone Mountain Park is a nature reserve and theme park all rolled into one. The biggest attraction is Stone Mountain, which has great views over Atlanta. The hike up is only a mile long and kids as young as four can easily make the climb. The park’s 3,200 acres also feature train rides, mini-golf, a laser show, and high-speed cable cars. There’s a campground for families who want to stay overnight and enjoy the festivals or special events.
