Located on Hengqin Island near Macao, in China's southeastern Guangdong province, Chimelong Ocean Kingdom is the world's largest aquarium by Guinness World Records. The 125-acre aquatic theme park features the world's largest aquarium, largest underwater viewing dome, largest aquarium tank, largest aquarium window, and largest acrylic panel — included in the whale shark exhibit's walk-through viewing tunnel.

The aquarium holds a whopping 5.99 million gallons of saltwater, and, all told, the park's seven themed areas contain a 12.87 million gallons of saltwater and freshwater. It's Asia's first theme park to combine themed entertainment shows and thrill rides with animal exhibits. The park's aquatic attractions include the whale shark exhibit, penguins, and polar bears, along with the more exotic pantropical spotted dolphins and Chinese white dolphins. Other entertainment options include a "4D" movie theater; Asia's first "winged coaster," Flying Over the Rainforest; and a roller coaster that also combines a live polar bear exhibit. It's one of the best efforts in Asia to create viewing interactions between people and animals.
