The resort has been served by the Zhuhai Changlong railway station on the Zhuhai–Zhuhai Airport intercity railway since 18 August,

In 2015, Chimelong Ocean Kingdom won the Thea Award for Outstanding Achievement over 169 international candidates, marking the first time the award was given to a Chinese theme park.

The ocean park holds the Guinness world record for being the largest aquarium in the world, it also had the largest aquarium window in the world according to the Guinness World Records, a single acrylic panel measuring 39.6 by 8.3 metres (130 by 27 ft).

The Journey of Lights parade won the 2018 Thea Award for outstanding achievement - live show.

Samuel Hung Ka-yiu, chairman of the Hong Kong Dolphin Conservation Society, said, "Ocean Kingdom seems to have imported everything." They are doing everything wrong. "They are doing everything you don't want them to do". Examples include polar bears confined in small areas demonstrating "repetitive pacing, swaying, head-bobbing or circling" and skin disorders in penguins kept in a sub-tropical environment.

Further criticism arises from a recent trade of orcas between China and Russia. In 2013 Russia captured wild orcas in the Sea of Okhotsk, two of which have been sold to China. "Now, a conservation group monitoring the capture of killer whales says it has discovered that Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) permits were applied for by Russia and granted for two wild-caught killer whales, also known as orcas, to be exported to China." Ocean Kingdom refuses to comment on whether they plan to display orcas in the future, but there are currently 50 aquariums in China, none of which have orcas on display.
