If you’ve heard people talk about the Georgia Aquarium like it’s the largest in the world, you’re not imagining things. For years, Atlanta has been known for having one of the biggest and most impressive aquariums anywhere, and it’s still widely recognized as one of the top few in the world by size and collection.
The short answer: Atlanta is home to one of the world’s largest aquariums, and it continues to rank at or near the top globally, especially when you look at total water volume and the size of its main tank.
