In downtown Atlanta, an aquarium holds 24 million liters of water in a single tank, making it the largest in the world. Inside swim whale sharks, manta rays, and thousands of other creatures.

The Georgia Aquarium rises from Atlanta's urban landscape like an unexpected portal to the ocean depths. Since opening its doors in 2005, this massive facility has transformed how visitors experience marine life, bringing together more than 100,000 animals from 500 different species under one roof.

Whether you're watching whale sharks glide past floor-to-ceiling windows or standing beneath a tunnel as manta rays soar overhead, the scale of life here creates moments that shift your perspective on what aquariums can be.

A Birthday Gift to a City

The Georgia Aquarium exists because of a birthday celebration halfway around the world. In 1999, Home Depot co-founder Bernie Marcus visited the Monterey Bay Aquarium for his 60th birthday. The experience inspired him to create something similar for Atlanta.

Marcus donated $250 million to make his vision real, and the aquarium opened in 2005 on five hectares north of Centennial Olympic Park. For seven years, it held the title of world's largest aquarium by total water volume, housing 40 million liters across eight themed areas.

Ocean Voyager and Beyond

The centerpiece Ocean Voyager habitat recreates the open ocean with 24 million liters of water, still the largest single aquarium tank anywhere. Inside swim whale sharks named Yushan and Taroko, alongside manta rays, groupers, sawfish, and about 65 other species that share this enormous space.

Beyond Ocean Voyager, visitors find beluga whales, an extensive coral reef teeming with tropical fish, African penguins, sea otters, and river ecosystems. The collection spans marine environments from cold arctic waters to warm Caribbean reefs.

Swimming with Giants

Few aquariums anywhere can house whale sharks, the world's largest fish species. Georgia Aquarium brought four young whale sharks from Taiwan, creating one of only a handful of facilities outside Asia where visitors can see these gentle giants.

The acrylic viewing tunnels put you directly beneath swimming manta rays and whale sharks, creating the sensation of walking on the ocean floor. The scale transforms abstract knowledge into visceral understanding. When a 20-foot whale shark passes overhead, filtering plankton with its massive mouth, statistics become irrelevant.

Georgia Aquarium Highlights & Tips

• Ocean Voyager Tunnel Walk through the 100-foot underwater tunnel beneath the main tank while whale sharks and manta rays swim overhead. This is the aquarium's signature experience.
• Whale Sharks Yushan and Taroko These are among the few whale sharks in aquariums outside of Asia. Watch feeding demonstrations to see these filter feeders in action.
• Beluga Whale Habitat Get close to these intelligent arctic whales. The viewing windows allow eye contact with these curious and social animals.
• Tropical Diver Gallery An enormous living coral reef display showcasing the biodiversity of tropical reef ecosystems with hundreds of colorful fish species.
• Visit on Weekday Mornings The aquarium draws large crowds, especially on weekends and holidays. Early weekday visits offer shorter lines and better viewing opportunities.
• Book Tickets Online Purchase timed tickets in advance through the website to guarantee entry and skip ticket counter lines during your visit.
• Plan for 2-3 Hours Allow enough time to explore all eight galleries and catch scheduled feeding times and animal encounters throughout the day.
• Parking Near Centennial Olympic Park The aquarium is located just north of Centennial Olympic Park in downtown Atlanta. Several parking garages are available nearby, or use MARTA public transportation.

The Georgia Aquarium represents something more ambitious than simply displaying marine life. By bringing whale sharks, belugas, and thousands of other creatures to landlocked Atlanta, it creates access to ocean ecosystems for millions who might never visit coastal waters.

Bernie Marcus's 60th birthday gift has become a place where children press their faces against glass to watch sawfish swim past, where adults stand speechless beneath the Ocean Voyager tunnel, and where the sheer diversity of aquatic life reminds us how much lives beneath the surface of our blue planet.
