No trip to Sanya would be complete without visiting Dadonghai. You will find a great seletion of restaurants and bars here. Russian food, Western food and even Indian food is available here. There are also several great bars located at the beach. Some of these bars operate until the wee hours. Dolphin Bar and Young Bar should be on your checklist as well as the Big Pineapple mall. In the evenings you can go to Dadonghai square and watch or even take part in the square dancing.
Great location and lots of places to eat! overall its a great beach! Clear ocean and lots of water sport activies.
