Among the most popular theme-parks in the whole of Asia, two are located in Hong Kong. One of them is Disneyland, and the other is Ocean Park. The latter one is a complex of amusement parks, marine mammal parks, oceanariums, etc. The Hong Kong Ocean Park opened in 1977 and since has become the integral part of the city’s life. The number of visitors per year is over 7 million and continues to grow every season. But what are the reasons why the Ocean Park is so much better than the similar venues in this part of the world? First of all, its Marine World area is truly stunning. It is a home to dozens of species of marine mammals and fish, ranging from huge sea lions to tiny sea jellies. It also features a massive roller coaster, the Dragon, which is the biggest in the city. Talking about big, the Ocean Park has the biggest observation towers in the world – the Tower, which, with its 200 meters tall structure offers an impressive view of the city. The other attractions of the Ocean Park include the Thrill Mountain, a large amusement park, featuring various types of roller coasters, trampolines, etc. There are also several zoos divided by geographical categories. For example, there is the Amazing Asian Animals area with rare species of Pandas, or the Rainforest, which features species from South America.
