Shanghai Ocean Aquarium

The Shanghai Ocean Aquarium sits right at the foot of the Oriental Pearl Tower in Lujiazui, making it an easy add to a Pudong skyline morning. The headline feature is one of the world's longest underwater viewing tunnels (155 meters), where sharks, rays, and groupers glide overhead on a moving walkway. Other zones are organized by geography — China, South America, Australia, Africa, Antarctica, and Oceania — with a strong Yangtze freshwater section featuring Chinese alligators and giant salamanders. It's compact enough for 1.5–2 hours, great for kids and rainy days. English signage is good throughout. Book Trip.com tickets a day ahead to skip the on-site queue.
