Xinga Beach is a perfect but not a secret beach. The water is so clear that you don't need to dive to see water bugs. Just a few meters, you can see so many different fish beside the beach. The beach is very big. You can rent a set of beach chairs with a Book here. There are many restaurants and bars.
Xinga beach is not big, but it is worth visiting. There are fewer people on it, but the water quality is very good and it is not seriously polluted.
