Why should you go there and how do you do it right?

Come for the tunnel and consider everything else a bonus. The transparent acrylic tunnel stretches over 105 meters through the aquariums, offering a 180-degree panoramic view. Blacktip reef sharks, giant groupers, and schools of trevally glide overhead, sometimes coming so close it feels like they're looking back. Kids love it. Parents enjoy a cool, dry hour away from the Pattaya heat. Other attractions include a touch pool with rock-dwelling fish from the Thai coast, a coral reef tank, the "Giant of Siam" tank with Thai freshwater fish surrounding a sunken ship, and a reptile enclosure near the exit.

Be realistic about the rest. Visitors frequently complain about areas closed for construction, tanks without live coral or plants, and a rather disappointing reptile exhibit. Some also feel shortchanged when parts of the aquarium are cordoned off. Skim the information, and you'll be back out in 45 minutes. Read the signs and stay for feeding time, and it will take an hour and a half to two hours. Feedings take place at 10:30 a.m. and 3:00 p.m. in the coral reef tank, at 11:00 a.m. and 4:00 p.m. in the ocean tank, and at 11:30 a.m. and 3:30 p.m. in the tank with the Giant of Siam. So, plan your walk through the tunnel so you can catch one of the feedings.

Arrive early. That's the most frequently given advice, and the tunnel is much more pleasant without the crowds pushing through.

The aquarium is open daily from 9:00 AM to 6:00 PM, with last entry at 5:30 PM. Adults pay 550 Baht, and children taller than 131 cm pay 320 Baht. The address is: 22/22 Moo 11, Sukhumvit Road, Nong Prue. If you booked through a third-party website, please have the PDF voucher from your confirmation email ready, not just the QR code. In the past, redeeming the voucher at the ticket counter has caused problems when only the code was presented.
