Underwater World Pattaya Aquarium: 100-Meter Tunnel

Sharks and rays circle overhead as you walk the tunnel floor.

Underwater World Pattaya is a modern aquarium in South Pattaya where you walk through a 100-meter transparent tunnel surrounded by sharks, rays, and schools of tropical fish, then explore themed zones including coral reefs, giant groupers, freshwater species, and jellyfish displays. Children from age 3 are welcome; the ticket you receive 24 hours before your visit is the one the attraction recognizes at the gate. Outside food is not permitted, and flash photography is restricted in certain areas.

The Experience

You arrive at Underwater World Pattaya and move through the themed zones at your own pace. The Touch Pool lets you interact gently with selected sea creatures in coastal-inspired habitats, and the Magic Tank delivers Thailand's only Mystical Gravity Interactive concept—a visual illusion that shifts as you watch. These hands-on moments break up the walk and give children something to do besides stand and look.

The centerpiece is the Coral Reef Zone's transparent tunnel, where colorful tropical fish swim past the acrylic dome above and around you. From there you move into the Open Ocean Zone to encounter Blacktip Reef Sharks and Giant Groupers—the larger predators that most people come to see. The Giant of Siam Zone shifts the focus to freshwater species arranged around a sunken ship habitat, and the Reptiles Zone closes the circuit with an impressive collection of snakes and other reptiles. The whole visit flows without a guide or a schedule; you spend as long as you want at each zone.

The aquarium is wheelchair accessible throughout, and strollers work on all surfaces, so families with infants and small children move easily. Public transportation runs nearby along Sukhumvit Road, or you can take a taxi or Songthaew directly to the entrance. The ticket arrives by email 24 hours before your visit—that is the official one to show at the gate, not the Viator confirmation you receive at booking.

Is this one for you?Choose the foreigner ticket if you are visiting Thailand on a tourist visa; Thai nationals and foreigners with a valid work permit need the Thai ticket and must present proof of status at the gate. The self-paced format works well if you have a free afternoon and want to move through the zones without a guide or fixed schedule, stopping longer at the tunnel and the predator zones.

Top questions

What is the 100-meter tunnel at Underwater World Pattaya?

The tunnel is a transparent acrylic passage on the aquarium floor where you walk beneath sharks, rays, and schools of tropical fish swimming in the water above and around you. It is the main attraction and gives you an up-close view of large marine predators and reef fish without entering the water.

Can I bring my own food and drinks into the aquarium?

Outside food and beverages are not permitted inside Underwater World Pattaya. Plan to eat before you arrive or purchase refreshments elsewhere in the area.

How do I get my actual ticket for Underwater World Pattaya?

The service provider sends your official ticket by email 24 hours before your visit date.
