If you are interested in swimming Serenity Bay beach nearly as good as the family beach, at least near the bar end of the Serenity Bay beach. The water is shallow, never got deeper than my chest and there are rocks and seaweed. The family beach was much nicer on the feet, and the water was deep enough to swim and float. Neither was very crowded when I was there on May 20, lots of space and choice of loungers at both beaches
