Where to book & compare
| Provider | From | Notes |
|---|---|---|
| Gate ticket (foreigner) | around 500 THB | Non-Thai and Thai rates are priced separately — buy the correct category. |
| Online e-ticket (Klook) | from ~375 THB | Meaningfully below gate. Select the foreigner ticket when booking; showing a Thai-rate ticket at the door causes problems. |
| Sea Life Bangkok (alternative) | — | Bigger and flashier if your trip includes Bangkok — but at roughly triple the price. For a Pattaya-based family day, this one does the job. |

Frequently asked questions
How much are Underwater World Pattaya tickets?
Online tickets for foreign adults start around 375 THB as of mid-2026, while gate prices run higher — around 500 THB. Children under 89 cm enter free. Thai and non-Thai visitors are ticketed separately, so pick the right category when booking online.
What are the opening hours?
09:00 to 18:00 daily, with last admission at 17:30 and ticket sales closing at 17:00. Mornings before the tour groups arrive are the quietest window.
How long does a visit take?
One to two hours. The aquarium is compact — six zones and the tunnel — and that is the honest framing: a good 90-minute outing, not a full-day attraction. It pairs well with Jomtien Beach or the Floating Market just down the road.
Is it worth it compared to bigger aquariums?
Kept honest: this is a mid-sized, older aquarium, and anyone who has done Sea Life Bangkok or Singapore’s S.E.A. Aquarium will find it modest. What it does well is price, location and toddler-scale walkability — for a Pattaya family morning, especially in rain or peak heat, it earns its ticket.
How do I get there?
It is on Sukhumvit Road at the southern edge of the city, about 10 minutes and roughly 100–150 THB by Bolt/Grab from central Pattaya or Jomtien. Any songthaew running the Sukhumvit corridor toward Sattahip passes the entrance.
