Chimelong Ocean Kingdom (Zhuhai)

Over 5.25 million square metres and eight themed zones, with whale sharks and manta rays in the tank. Close enough to work into a border-crossing itinerary — especially if you're already travelling via Hengqin or Macao.

Chimelong Ocean Kingdom in Zhuhai is one of the world's largest aquarium/marine parks and sits right by Macau and the Hong Kong–Zhuhai–Macau Bridge, a natural add-on for visa-free transit and Macau/HK travelers.

Signage and menus inside are mostly Chinese and the multi-language audio guide is a paid add-on; being next to Macau, plan the HZM Bridge / border crossing into your day.
