Daidai Island is located in the southwestern coastal area of Nanwan Peninsula, about 14 kilometers south of Lingshui County, Hainan Province. It is adjacent to Qingshui Bay Resort in the west and Wuzhizhou Island in the south across the sea. The coastline of the beach on the island is about 5.9 kilometers in length. It is a long and well-protected beach on the east coast of Hainan Island. Walking on the clean and soft sandy beach of Dudai Island, you can see coconut grove swings, bubble houses, white chapels, pink cars, beach pavilions, abandoned fishing boats and other facilities everywhere. In this place where the sky is blue and the water is pure, accompanied by the surging white waves, any photo taken is a photo with its own filter. It is beautiful and romantic, and it can be called a photo-taking place.
