Koh Sak is a small island with an interesting history. It once played host to several known personalities, including Neil Armstrong, the Duke of Edinburgh, and the Shah Reza Pahlavi of Iran. Former presidents of the United States and the late king of Thailand were patrons on this island too. Therefore, one can only expect a lot from this star-studded island that once played host to a variety of rich and famous personalities. Visitors can see for themselves the hand and footprints left by these royalties along the concrete pathway found on the island.
Koh Sak has since become a part of the national park, and there is no permanent settlement on this island anymore. Its primary residents today are hawksbill turtles and bamboo sharks. The population of bamboo sharks in the waters surrounding the island serves as a caution for avid scuba divers. Nevertheless, the island remains to be a trendy destination for divers and snorkelers alike. Its sheltered bay is perfect for beginner divers. For more advanced divers, one can find the wrecks left by the HTMS Kut along the east coast.
Koh Sak is shaped like a horseshoe and sits about 10km west of Pattaya and 600m from its neighboring island, Koh Larn (Coral Island). Being a very accessible island, Koh Sak makes a perfect island-hopping stop during a day trip from Pattaya.
