There are two uninhabited islands in the Shimei Bay area, Jiajing Island and Zhouzi Island. Because there is no one to live there is no sewage discharge and garbage pollution. The island's environment is better preserved and grows in the lagoon area. With beautiful colored corals, corals will have tropical fish and beautiful diving, which is the biggest difference between these two wild islands and Wuzhizhou Island. No tickets are required for these two islands, but an outdoor club is required to take the boat to get to the island. Kajing Island is in Wanning, about 2 hours drive from downtown Sanya. I believe that the first time you arrive, you will like the white sand beach and the blue and green waters, but this is not the point. The focus is on the most beautiful coral reefs in Sanya under the sea, making it the best place for snorkeling and deep diving.
