This is Guandao Cave, the tallest sea arch in Hong Kong at 45 meters high. Located on Basalt Island in Sai Kung, it features striking hexagonal volcanic rock columns, photogenic locations, and plenty of explorable spots, both under and above water and is part of the Hong Kong UNESCO Global Geopark. Accessible by speedboat, it offers breathtaking views and unique exploration opportunities. #islandhopping #islandvibes #island #foryou #explore | Arcee Xandrah Rain

Yanzi Cave in Shanqin Bay, Wanning, and it is recommended to drive there. After getting out of the car, you need to walk through a sandy beach covered with reefs. If you love to catch sea #creatures, there are many soldier #crabs on the rock walls here, which will make them very happy. | Hainan Touch
