Wanlitong is located on the west side of Hengchun, a small village between Shizhu and Zhiguangzui. The coastline is about one kilometer long and forms a broad intertidal zone due to the flat reefs in the reef area. The rich biota in the intertidal zone, coupled with the clean and beautiful underwater landscape, attract many tourists to snorkel here. A good snorkeling spot is here. When snorkeling in the intertidal zone below 10 meters above the sea surface, you can see rock caves, rock caves, reef mounds and other characteristic terrain landscapes, which are covered with various coral groups: soft corals, stony corals, Sea fans and other colorful coral fish swim through it, and it has been planned as a marine ecological reserve.
