Another place to visit is Underwater World. Underwater World is probably the most unique experience you are going to have in Singapore. You have a chance to feed marine animals e.g. manta rays and sharks and to see a master of disguise like the amazing mimic octopus. And other activities e.g. you can enjoy swimming with dolphins and shark, dining underwater, or trying a fish spa. All part of what is genuinely an unforgettable experience.
