Siam Ocean World

Southeast Asia’s largest oceanarium is also one of its most impressive. More than 400 species of fish, crustaceans and even penguins populate this vast underground facility. The oceanarium is divided into 12 zones accommodating specific species. The main tank is the highlight, with an acrylic tunnel allowing you to walk beneath sharks, rays and all manner of fish. Diving with sharks is also an option if you have your diving licence (for a fee), though you’ll have almost as much fun timing your trip to coincide with the shark and penguin feedings; the former are usually at 1pm and 4pm, the latter at 12.30pm and 4.30pm – check the website for details.
