Underwater World Pattaya was among Thailand’s earliest acrylic-tunnel aquariums. It is fully indoor and air-conditioned, and houses more than 5,000 marine animals, many of them native to the seas around Thailand. The route takes you past tanks of coral, jellyfish and seahorses before reaching the main ocean tunnel, where sharks, stingrays and turtles swim overhead and on either side. Trip Dust supplies a confirmed entry ticket and answers your questions on WhatsApp, which keeps the visit simple to plan around the rest of your Pattaya itinerary.
The aquarium is divided into themed zones, each holding a different group of species:
- Coral Reef Zone — tanks of clownfish, parrotfish and other tropical reef fish kept among living coral.
- Open Ocean Zone (the tunnel) — the main draw, a 100-metre clear acrylic walk-through tunnel with blacktip reef sharks, eagle rays, large groupers and sea turtles.
- Giant of Siam Zone — the large freshwater fish of Thailand’s rivers, including the Siamese giant carp, which can grow to several metres.
- Jellyfish Zone — low-lit, colour-changing tanks holding what the aquarium describes as one of Thailand’s largest jellyfish displays.
- Touch Pool & Seahorse area — a shallow pool where children can handle starfish and sea cucumbers under supervision, alongside a seahorse tank.
- Reptiles Zone & Magic Tank — a small reptile section and an optical-illusion tank aimed at younger visitors.
At set times during the day, divers run feeding shows at the larger tanks, hand-feeding the sharks, rays and giant fish while explaining each species. Walkways are flat and entirely indoors, which makes the layout manageable for grandparents and young children alike. For anyone interested in marine life, or simply looking for a cool indoor stop on a hot Pattaya afternoon, it covers both.
