If you’re planning to visit Atlanta, Georgia, you probably already know about some of the big attractions in the city such as the World of Coca-Cola or Stone Mountain Park. If you have time to see some additional sights while in town, here are five cool, hidden, and unusual things to do in Atlanta that you may not know about! Check out these sights on your next trip!

Secret Cave at Stone Mountain
Stone Mountain is most famous for its huge Confederate Memorial Carving of three leaders of that side in America’s Civil War. But hidden away on one of its outer edges is a small cave that you can explore and learn about Indian history at Stone Mountain. It was used by Indians for many years as a secret cave full of gifts from lovers that were left there for safekeeping. There are also interesting displays about how Stone Mountain got made into what it is today. The gift shop has cool books about Indian legends to take home with you too if you want them! Allegiant Airline Reservations invites you to travel throughout the world at a low cost. 

Visit Lake Lanier
Lake Lanier is one of Georgia’s largest lakes and encompasses about 12,000 acres. It straddles three counties—Hall, Forsyth, and Banks—and offers residents a great place for water sports. There are two golf courses on its banks as well as plenty of boat rentals; other lake activities include swimming, scuba diving, skiing (yes!) fishing (also yes), sailing (of course), jet skiing (naturally), waterskiing (it’s what they do in Georgia), tubing (yep), canoeing/kayaking (of course!), speed boating/motorsailing/jet boating/windsurfing/kiteboarding...get it? There’s also a boat launching ramp just south of Loganville.

Explore Krog Street Tunnel
Since 1921, thousands of cars have driven under downtown Atlanta on Krog Street. The street originally began as a concrete road built during World War I. It was supposed to last only 20 years before being turned into a greenway (or park). But then cars came along and made it too expensive to tear down. Cars use an underground tunnel that measures 5400 feet long. Several sections are closed off from car traffic due to flooding and damaged roads from water seeping through cracks in walls, which is pretty cool for an urban explorer like you! Explore at your own risk!

Enjoy the Seasons on Piedmont Park
When many people think of downtown Atlanta they don’t picture Piedmont Park. This huge green space on 10th Street may not be an urban oasis—it’s actually surrounded by high-rise buildings—but it feels like one. Especially during springtime when azaleas are blooming, or during summer when you can lounge beside a pond full of ducklings. On summer weekends there is often live music playing on its main stage and children running around having fun at one of its many play areas. In fact, Piedmont Park offers a surprising amount of activities for families. It also gives you easy access to other attractions such as Zoo Atlanta that are sure to delight kids and adults alike!
