In 2005, Ocean Park announced a HK$5.5 billion Master Redevelopment Plan (MRP)to build the Park into the world’s best marine-based theme park, doubling the amount of animal and ride attractions, from 35 to over 80, and firmly establishing itself as a world-class, must-see landmark that will further strengthen Hong Kong as a premier tourist destination. Attractions opened under the MRP include: Amazing Asian Animals, Ocean Express, Aqua City, the Rainforest, Thrill Mountain and Polar Adventure. The brand new Aqua City, showcasing a Grand Aquarium with 3 levels of viewing galleries approximately four times the size of the Atoll Reef; the Amazing Asian Animals themed-area, which incorporates the themed Giant Panda Adventure, highlighting some of Asia's rarest creatures; a redeveloped children's area called Whiskers Harbour and an array of refreshment and retail facilities. At The Summit, guests can visit the Polar Adventure to feel the chill of the North and South Pole, or journey down river rapids to discover the beautiful Rainforest. Thrill seekers hunting for excitement need look no further than Thrill Mountain. The Ocean Express opened in 2009, it was built to transport up to 5,000 people per hour in each direction between The Waterfront and The Summit in less than 3 minutes.

Going hand in hand with the leaps Ocean Park has made in terms of developing itself are the numerous achievements the Park has earned for its achievements in the field of animal conservation. As a member of the World Association of Zoos and Aquariums (WAZA), we continuously strive to maintain the welfare of the animals under our care, encourage audiences to respect the environment and help our community conserve it. The Park has gained accreditation from the Association of Zoos and Aquariums (AZA) over five consecutive five-year accreditation cycles and is the first institutional member in Asia to earn this important recognition and validation of responsible animal care. Ocean Park is also aligned with WAZA’s animal welfare strategy and provides valuable contributions to this important element of biodiversity conservation. The animal welfare standards at the Park were also audited by the Global Humane Society under its Humane Conservation certification programme. It has demonstrated that Ocean Park has a culture and staff dedicated to providing the best care and welfare for the animals in its collection.

The Park's continuing commitment to animal conservation is reflected in the successful breeding programmes undertaken for its unique collection of insects, fishes, birds and marine mammals. Births of rare shark species, sea lions, sea horses and different species of jelly fish have been recorded, while endangered birds and butterflies are also being hatched and reared at Ocean Park. Research and development into breeding marine mammals via artificial insemination (AI) produced the world's first bottlenose dolphin pregnancies through AI in 2000. This was followed by the births of the world's first two bottlenose dolphin calves achieved via AI in May 2001.

As part of its initiatives to coordinate international conservation efforts for endangered marine mammals in Asia, Ocean Park established the Ocean Park Conservation Foundation (OPCF) in 1993. The Foundation hoped to significantly improve attitudes and practices towards conservation in Hong Kong and Asia through cooperative programmes with other conservation organisations. The Hong Kong Society for Panda Conservation (HKSPC) was also launched in 1999 to educate the community and support conservation of the giant pandas and their habitat. Both the HKSPC and OPCF were merged into a single organisation on 1 July 2005 as the Ocean Park Conservation Foundation Hong Kong (OPCFHK). The OPCFHK advocates, facilitates and participates in the conservation of wildlife and habitats, with an emphasis on Asia, through research and education.

The Cable car and The Ocean Express are two main transportation to enable guests to move between The Waterfront and The Summit. The 1.5 km long cable car system offering not only just a convenient but also exceptionally scenic route between these two areas, with spectacular panoramic views of the southern side of Hong Kong and the South China Sea.

The Summit is home to Ocean Park's many thrill rides, including Hair Raiser, Whirly Bird, Bumper Blaster, The Flash and Rev Booster. There are also rides such as Crazy Galleon, Ferris Wheel and Flying Swing in the Marine World nearby.

And Pacific Pier brings a slice of the sunny Californian coast to Hong Kong, complete with an interactive underwater exhibit view of the sea lions at play.

The Waterfront features Ocean Park's latest themed-area, the Amazing Asian Animals – an educational and highly entertaining collection of exhibits bringing together some of Asia's rarest animals. Red Pandas will be making their debut in Hong Kong for the first time ever at the Giant Panda Adventure, which will also house giant pandas Ying Ying and Le Le. For the bird watchers, the Panda Village offers a great opportunity to spot Ocean Park's avian friends high above the trees, as well as visit some delightful Asian Small-clawed Otters.
