The title of world’s largest aquarium has changed hands several times in recent decades, and understanding which facility currently holds the record depends on how you measure size. This matters because the aquarium you choose to visit will shape your entire trip, from the city you fly into to the time and budget you’ll need.
This guide explains which aquariums compete for the largest title, what makes each one exceptional, how to plan a visit, and what you’ll actually experience at these massive marine attractions.
Which Aquarium Is the Biggest in the World?
Chimelong Ocean Kingdom in Hengqin, China currently holds the Guinness World Record for largest aquarium by water volume, containing approximately 48.75 million liters of water across multiple exhibit tanks. The Georgia Aquarium in Atlanta, United States held this title from 2005 to 2012 and remains one of the world’s largest facilities, while several other contenders measure their size differently, by total tank volume, exhibit space, or number of animals.
The Leading Contenders
Several aquariums legitimately compete for the largest designation. Each measures its size using different metrics, and visiting one versus another creates entirely different travel experiences.
Chimelong Ocean Kingdom
Located in Hengqin, Zhuhai, Guangdong Province, this aquarium opened in 2014 and quickly set multiple records. The facility contains eight themed zones and holds whale sharks, manta rays, beluga whales, and polar bears across its exhibitions.
The aquarium sits within the larger Chimelong International Ocean Resort. You’ll need at least a full day to see the main exhibits, shows, and outdoor rides integrated into the complex.
Hengqin is accessible from Macau and connects to mainland China. Check current visa requirements for entry into China well before booking, as regulations vary by nationality and change periodically.
Georgia Aquarium
This Atlanta facility opened in 2005 and contained the world’s largest aquarium tank until Chimelong’s opening. The Ocean Voyager exhibit, built with a 100-meter-long viewing tunnel, holds approximately 24 million liters of water and houses whale sharks, manta rays, and thousands of other fish.
The aquarium sits in downtown Atlanta near Centennial Olympic Park, the World of Coca-Cola, and the Center for Civil and Human Rights. Most visitors spend three to five hours exploring the main galleries and shows.
Public transit via MARTA connects the aquarium to the airport and major Atlanta neighborhoods. Paid parking is available on-site, but fills quickly during weekends, holidays, and summer months.
S.E.A. Aquarium
Part of Resorts World Sentosa in Singapore, this aquarium opened in 2012 and once held the volume record before Chimelong. The Open Ocean habitat features a 36-meter-wide viewing panel and contains manta rays, goliath groupers, and schools of trevally.
The aquarium connects to Universal Studios Singapore, Adventure Cove Waterpark, and several hotels on Sentosa Island. Plan two to three hours for a thorough visit, or combine it with other Sentosa attractions across a full day.
Sentosa is accessible from mainland Singapore via Sentosa Express monorail, cable car, bus, or pedestrian boardwalk. Verify current admission prices and combination tickets through the official Resorts World Sentosa website.
Dubai Aquarium & Underwater Zoo
Located inside The Dubai Mall, this aquarium features a 10-million-liter main tank visible from the mall’s public areas. The 48-meter-long walkthrough tunnel and underwater zoo require paid admission.
The aquarium houses sand tiger sharks, stingrays, and a large collection of groupers. You can view the main tank for free from the mall, but access to the tunnel, behind-the-scenes tours, and animal encounters requires tickets purchased in advance or on-site.
The Dubai Mall connects directly to the Burj Khalifa and sits on the Dubai Metro Red Line. Expect significant crowds during weekends, public holidays, and the cooler months from November through March.
What You’ll Actually See
The largest aquariums share certain features but offer distinct experiences. Understanding what each facility prioritizes helps you choose the right destination.
Marine Life Collections
All major aquariums house whale sharks, the world’s largest fish species, along with manta rays, sharks, groupers, and thousands of smaller fish. Some facilities also maintain marine mammals including beluga whales, dolphins, sea lions, or seals, depending on local regulations and the facility’s conservation philosophy.
Specific species vary by location and change as animals grow, breeding programs succeed, or conservation priorities shift. Check the aquarium’s current animal roster on its official website before visiting if seeing particular species matters to your trip.
Viewing Experiences
Large aquariums typically feature underwater tunnels, multi-story viewing windows, and open-top exhibits. The most impressive views often come during feeding times or scheduled presentations when fish gather near the surface and staff provide context.
Crowds significantly affect your viewing experience. Arrive at opening time or during weekday mornings for the clearest views and easiest access to popular exhibits.
Beyond the Tanks
Modern aquariums include touch pools, 4D theaters, behind-the-scenes tours, animal encounter programs, and educational presentations. These experiences usually cost extra beyond general admission.
Some facilities offer night visits, sleepovers, or dive experiences for certified divers. Book these specialty programs weeks or months in advance, as space is limited and some programs run only on specific dates.
Planning Your Visit
Visiting one of the world’s largest aquariums requires more planning than a typical attraction. These facilities draw millions of visitors annually and anchor larger tourism districts.
Choosing Your Destination
Select an aquarium based on your broader travel plans rather than size alone. If you’re already planning a trip to Singapore, S.E.A. Aquarium integrates easily into a Sentosa Island day; if you’re visiting Atlanta for other reasons, the Georgia Aquarium becomes a logical addition.
Consider visa requirements, flight costs, language barriers, and total trip expenses when choosing between international options. A slightly smaller aquarium in a more accessible location often provides a better overall experience than the absolute largest facility requiring complex travel logistics.
When to Go
Peak visiting times create crowded viewing areas and longer waits for exhibits, shows, and interactive experiences. Summer vacations, winter holidays, and local public holidays bring the largest crowds to all major aquariums.
Weekday mornings during school terms typically offer the quietest visits, though some aquariums host school groups mid-morning. Check the facility’s calendar for special events, maintenance closures, or exhibit rotations that might affect your visit.
Tickets and Timing
Most large aquariums use timed entry tickets purchased online in advance. This system controls crowd levels and often offers lower prices than same-day admission.
Allow three to five hours for a comprehensive visit to a major aquarium, including shows, feeding presentations, and time in specialty exhibits. Visitors with children or those who read every educational display may need a full day.
Accessibility Considerations
Major aquariums provide wheelchair access, elevators, and accessible restrooms throughout their facilities. Viewing tunnels, ramps, and multi-level exhibits accommodate most mobility devices.
Sensory experiences vary significantly between quiet galleries and loud, crowded show areas. Some aquariums offer sensory-friendly hours or quiet spaces; confirm availability and requirements through the facility’s accessibility services before your visit.
Getting There and Around
Each major aquarium sits in a different urban context with distinct transportation options. Plan your arrival considering traffic patterns, parking costs, and public transit schedules.
The Georgia Aquarium benefits from Atlanta’s MARTA rail system and downtown hotel walkability. S.E.A. Aquarium connects seamlessly to Singapore’s extensive public transit network. Chimelong Ocean Kingdom requires more deliberate planning, typically involving taxi or shuttle service from Macau or Zhuhai. Dubai Aquarium sits inside a massive shopping mall served by metro, taxi, and ride-sharing services.
If driving, verify parking rates and availability before your visit. Popular aquariums often have on-site parking that fills by mid-morning on busy days, requiring overflow lots or garage parking at premium rates.
Budget Expectations
Admission prices for major aquariums range considerably by location and date. General admission typically costs between $30 and $60 per adult at current rates, with discounts for children, seniors, students, or local residents where applicable.
Additional costs include parking, specialty experiences, behind-the-scenes tours, animal encounters, food, and gift shop purchases. A family visit can easily exceed $200-300 once you include these extras.
Combination tickets with nearby attractions sometimes offer better value than single-site admission. Research city passes, multi-attraction tickets, or membership programs if you plan to visit multiple times or have flexibility in your schedule.
What to Skip and What Matters
Not every exhibit, show, or experience justifies your time and money. Focus on what makes each aquarium unique rather than trying to see everything.
At Chimelong, prioritize the whale shark exhibit and the beluga whale display. At Georgia Aquarium, the Ocean Voyager tunnel and dolphin presentations stand out. S.E.A. Aquarium’s Open Ocean gallery and shipwreck theme create its most memorable moments.
Skip redundant exhibits if you’re short on time. Most large aquariums feature similar jellyfish galleries, tropical reef tanks, and touch pools; after seeing one well-executed version, you can move on without missing much.
Responsible Visiting
Large aquariums walk a complex line between entertainment and conservation. Many conduct legitimate research, breed endangered species, and educate millions of visitors about ocean health and marine biology.
Follow all facility rules regarding flash photography, which can stress certain animals. Don’t tap on glass, feed animals unless explicitly invited during supervised programs, or reach into tanks beyond designated touch pool areas.
Ask staff about the aquarium’s conservation programs, sustainable seafood initiatives, and animal welfare standards if these issues matter to you. Reputable facilities openly discuss their practices and accreditations.
Nearby Experiences
The world’s largest aquariums rarely stand alone. They anchor entertainment districts with museums, theme parks, shopping, dining, and other attractions within walking distance or a short transit ride.
In Atlanta, combine the Georgia Aquarium with the World of Coca-Cola, National Center for Civil and Human Rights, or a CNN Studio Tour. Singapore’s Sentosa Island clusters Universal Studios, beach clubs, nature trails, and resort hotels around S.E.A. Aquarium. Chimelong sits within a resort complex offering theme parks and circus shows.
Plan multiple days in the destination city to see the aquarium without rushing and explore surrounding attractions. Single-day visits to major aquariums often feel hurried and limit your ability to experience the broader destination.
Making the Most of Your Visit
Success at a major aquarium comes down to managing expectations and timing. These facilities entertain and educate millions annually but cannot provide intimate wildlife encounters or empty viewing galleries during peak season.
Download the aquarium’s app if available for maps, show times, feeding schedules, and real-time crowd updates. Eat lunch before or after typical meal hours to avoid crowded cafeterias and long waits.
Bring a refillable water bottle, as walking through large climate-controlled exhibits for hours creates thirst. Wear comfortable shoes for extended standing and walking on hard floors.
Final Considerations
The world’s largest aquarium title changes as new facilities open and existing ones expand. More important than chasing the current record holder is choosing an aquarium that fits your travel plans, budget, interests, and accessibility needs.
Verify all time-sensitive details including admission prices, opening hours, seasonal closures, special events, health requirements, and visa regulations through official sources before finalizing your plans. Check the specific aquarium’s website and relevant government tourism or immigration offices for current information.
Start planning by deciding which destination city you want to visit, then build your aquarium experience into a broader trip that balances marine life with the region’s other attractions, culture, and practical visitor needs.
