Underwater World Pattaya is an indoor aquarium on Sukhumvit Road — the answer to a day too hot or too wet for the sea.

The tunnel

Its centrepiece is an underwater tunnel roughly 100 metres long, walked with fish moving alongside and overhead. It takes the longest and is the main reason people come.

There are also feeding sessions at set times — check the schedule when you buy your ticket and plan your route around it.

Planning

• Allow one to two hours
• Suits families with children, and makes a reliable wet-day fallback
• Entirely indoors, so the sun is not a factor
• Check admission and feeding times in advance
