Underwater World Pattaya is an indoor aquarium on Sukhumvit Road in South Pattaya, with marine life from Thailand and other waters. Its 105-metre acrylic tunnel takes you beneath sharks, rays and shoals of fish, while themed areas include coral reef, open ocean and the Giants of Siam. Feeding demonstrations and a touch pool add hands-on interest for families, and the giant Arapaima and jellyfish displays give you more to look for. It is a manageable indoor stop for a hot or rainy day.
Walking beneath the marine life
The aquarium’s main draw is its long acrylic tunnel. As you walk through, you can look around at sharks, rays and schools of fish moving above and beside you. The clear tunnel creates a close view without putting you in the water.
Different descriptions give the tunnel’s length as around 100 to 105 metres. The aquarium’s zones include the Coral Reef Zone, the Open Ocean Zone and the Giants of Siam Zone, which has a shipwreck display. Together, they give the visit a route through several kinds of marine environments rather than one continuous tank.
What to look for
Sharks and rays are among the most visible animals in the tunnel. Keep an eye out for stingrays, turtles and tropical fish, as well as the giant Arapaima, a large freshwater fish that stands apart from the marine displays. The jellyfish collection is another highlight.
The aquarium also has a touch pool, where visitors can encounter some smaller sea creatures. Follow the staff’s instructions at the pool and handle the animals only as permitted. Feeding demonstrations bring a different kind of activity to the tanks, with fish gathering around as food is given.
Planning a family visit
Underwater World is on Sukhumvit Road in South Pattaya. Its indoor setting makes it an option for a hot afternoon or a rainy day, particularly if you are visiting with children. A typical visit takes about one to two hours, so it can fit into a day with other plans.
Arriving early or choosing a weekday can mean a quieter visit. If a feeding demonstration is a priority, check its timing before setting out; the available information does not give a fixed schedule. Advance tickets are recommended, and booking online may come with a discount. The aquarium has a cafe and gift shop, along with parking on site.
