Buy a ticket and join the fans at a game at RE-MAX Greater Atlanta Stadium. If there's nothing happening while you're there, you might like to check if there's a guided tour of the grounds.
Located in Atlanta, this sporting facility is well worth including on your itinerary. But you'll find lots more to explore in this area. Perimeter Mall, Northlake Mall, and BAPS Shri Swaminarayan Mandir aren't too far from RE-MAX Greater Atlanta Stadium.
