The resort has a unique geographical location, located in the center of the thirty-kilometer-long Sanya Bay, facing the beautiful East Island and West Island. The azure blue sea and the silver-white sandy beach are ideal places for outdoor and entertainment activities. The 30-kilometer "Binhai Avenue" and "Coconut Dream Corridor" complement each other with the azure blue water. The silver sandy beach, the sunset, and the golden The sunset, the fishermen returning in the evening, and the gorgeous sunset are just like an ingenious picture of the world.
