Construction

The project began with an estimated budget of S$140 million as well as an annual visitor rate of 750,000, however since the original announcement in 2009 the budget has since increased by S$20 million in 2010, due to rising construction costs, to S$160 million and the annual visitor rate has also increased to 820,000.

Attractions
The park boasts a tropical rainforest setting along with as river theme with various animal attractions, theme park rides and other major exhibits.

Giant pandas
One of the main attractions is a pair of male and female giant pandas – Kai Kai (凯凯) and Jia Jia (嘉嘉) – which are housed in a specially constructed climate-controlled enclosure which change throughout the four seasons emulating their original environment. The zoo grows its own 8000 m2 plantation of special bamboo specially for the feeding of the giant pandas. These pandas are a sign of the twentieth anniversary of friendly Sino-Singapore relations. The park also received a conservation donation from CapitaLand. The names of the two pandas were selected from entries of a public naming competition organised in 2010. The pandas, which arrived in September 2012, are on a ten-year loan from China.

On 14 August 2021, a panda cub was born to Kai Kai and Jia Jia, later revealed to be a male on 10 September. This was the first after seven breeding rounds since 2015, which did not yield any cubs. The panda cub was conceived via artificial insemination.

During the first few days after the cub was born, Jia Jia was given fluids as well as a glucose diet to get through the trying period with her mothering skills improving by the day.

Subsequently, on 26 August 2021, Mandai Wildlife Reserve (then Wildlife Reserves Singapore) announced that the cub will return to China once it turns two, the age when it matures. The cub also has black markings being more apparent by the day. Discussions are also ongoing with Chinese authorities to extend Kai Kai and Jia Jia's stay beyond 2022, the initial period when the pandas are supposed to return. This is to allow for more breeding programmes to be conducted after the cub separates from the parents.

On 22 September 2021, the cub opened his eyes to the world for the first time when he was 40 days old with the panda cub weighing 1.87kg, an increase of 370g from the previous week. Two weeks later, the panda weighed 2.638kg as at 1 October.

On 8 October 2021, the cub was revealed to have teeth quicker than expected, given that the teeth were formed two months after birth instead of the three typically. This meant that it could start eating bamboo soon. Six teeth were seen, with the first forming on 23 September. On 6 October, the panda weighed over 3kg with its length taken as 51.5cm from head to tail. The panda weighed 4.18kg as of 22 October with the length at 59.5cm from head to tail.

It was revealed on 19 November 2021 that the panda took its first steps and weighed 6kg with a length of 67cm.

On 29 December 2021, the panda was named Le Le (叻叻) based on the name "Shi Le Po" (石叻坡), an old Chinese term for Singapore. Le Le debuted the following day at its new nursery in the Giant Panda Forest. On 10 March 2022, Le Le joined Jia Jia in the main exhibit with the information board unveiled.

On the 13th of December 2023, Le Le made his last public appearance to Singaporeans. On the 16th of January 2024, Le Le touched down in Chengdu on a Singapore Airlines Boeing 747-400F freighter aircraft, where he will contribute to the conservation project for pandas.

The park's boat ride, the Amazon River Quest, was opened to visitors on 7 December 2013. It takes visitors through several animals from South America.
