Where is the World’s Largest Aquarium?
The title of the largest aquarium in the world belongs to the Chimelong Ocean Kingdom in Hengqin, Zhuhai, China. Opened in 2014, it quickly made headlines for its sheer size and breathtaking design.

- It holds the Guinness World Record for the largest aquarium.
- The main tank alone contains over 22.7 million gallons (68 million liters) of water.
- It features one of the largest acrylic viewing panels ever built, giving visitors an unparalleled window into ocean life.
If you’ve ever felt amazed by a regular-sized home aquarium, picture this place as your fish tank multiplied by a thousand.
What Makes Chimelong Ocean Kingdom Special?
Chimelong isn’t just an aquarium—it’s more like an aquatic wonderland combined with a theme park. Let’s break down some of its unique features.
- Diverse Marine Life: You’ll find whale sharks, manta rays, dolphins, sea lions, polar bears, and countless species of tropical fish.
- Immersive Experiences: From glass tunnels to enormous viewing windows, it feels like you’re walking inside the ocean itself.
- World Records: Apart from being the largest aquarium, it boasts record-breaking viewing panels, tanks, and attractions.
- Entertainment Meets Education: It’s not only fun but also promotes conservation, research, and awareness about marine ecosystems.
When people say “you’ll feel small in the presence of giants,” they aren’t exaggerating here. Standing in front of a whale shark inside Chimelong really makes you realize how vast the ocean world is.
How Big Is the World’s Largest Aquarium?
Numbers can sometimes feel boring, but here, they tell a jaw-dropping story.
- Main Tank Size: 22.7 million gallons (68 million liters).
- Acrylic Viewing Panel: 39.6 feet tall and 118 feet wide—imagine the size of a cinema screen but underwater.
- Total Park Area: The aquarium is part of a massive 132-hectare theme park complex, which also includes roller coasters, water rides, and theaters.
For comparison, a typical home aquarium might hold 20–50 gallons of water. That’s less than one second’s worth of water flowing into Chimelong’s tanks!
Animals You Can See in the World’s Largest Aquarium
One of the biggest attractions is, of course, the incredible diversity of marine life. Here’s a glimpse of what you’ll find:
- Whale Sharks – The gentle giants of the ocean.

- Polar Bears – An unusual addition to an aquarium but fascinating to see.
- Jellyfish Displays – Glowing and almost hypnotic.

Each exhibit feels like opening a window to a different corner of the ocean.
