Ocean Park Hong Kong, commonly known as Ocean Park, is a marine mammal park, oceanarium, animal theme park and amusement park situated in Wong Chuk Hang and Nam Long Shan in the Southern District of Hong Kong. It is, together with Hong Kong Disneyland, one of the two largest theme parks in Hong Kong. Opened in 1977 by the then Governor of Hong Kong Sir Murray MacLehose, Ocean Park became popular but by 2005 was unprofitable and widely expected to lose out to the new Hong Kong Disneyland. However, the Park responded with a HK$5.5 billion development plan that saw it expand to over 80 attractions and rides, and steadily grow visitor numbers to 7.6 million in 2014, making it the world's 13th most visited theme park, and the largest theme park in Asia. Half of all visitors now come from mainland China, in growth that parallels rising mainland tourist visitor levels to Hong Kong over the same period.
