With over 400 sea species and 30,000 fish on display, SEA LIFE Bangkok Ocean World Aquarium in Bangkok is one of the few in the world where families can spend a few hours without feeling bored. An acrylic tunnel runs through the main tank where you can boat along – or, if you are brave, why not dive in to feed the sharks? If that's too much, there are other underwater sea creatures you can feed and interact with: water rats, otters, the lovely penguins. At the end of the trip, don't forget to pamper your tired feet with a little fish pedicure!
