The best diving season is between October/November till April. The best sites are on the west and southern tip of the island, between Koh Chang and Koh Kood. There you can see soft corals, anemones, myriad reef fish, and sometimes eel. Hin Luk Bat and Hin Lap both have coral seamounts. Further south, white-tip reef sharks can be found near Hin Phrai Nam.
