Snorkeling on the two islands first and having lunch on the third island. The water was very very clear just as the advertisements. When we were in the water, fishes were around us and there were many kinds of fish and they were so colorful. The corals were not good anyway. After having lunch we stayed for an hour longer when we could swim and snorkel on the beach. So enjoyable. It is indeed one of the signature activities on the island.
