Just a one-hour boat ride from Koh Samui across the Gulf of Thailand lies the breathtaking Mu Ko Ang Thong National Marine Park. Comprised of 42 islands, the park spans a total area of 102 square km, with 18 square km of pristine island landscapes. Famous for its stunning beaches, vibrant marine life, and crystal-clear waters, Mu Ko Ang Thong is a paradise for boaters, snorkelers, and SCUBA divers alike.
SCUBA diving is the best way to truly experience the rich underwater ecosystem of these islands. Divers can expect to encounter butterflyfish, angelfish, parrotfish, stingrays, blacktip sharks, groupers, and delicate cowrie shells. If luck is on your side, you may also spot short-bodied mackerel, anchovies, and squid darting through the coral reefs.
One of the most celebrated dive sites in the park is Chumphon Pinnacle, famous for its vibrant anemones, each home to resident anemonefish. Schools of batfish, jacks, and barracudas roam the waters, adding to the thrill of the dive. However, the main attraction between February and April is the majestic whale shark—the largest fish in the world. An encounter with this gentle giant is an unforgettable experience.
Another must-visit dive site is Sail Rock, a towering underwater pinnacle frequented by whale sharks. Whether diving beneath the surface or watching from above, these graceful creatures linger for long periods, seemingly unfazed by the attention. Sail Rock is also home to batfish, trevallies, and reef sharks. For adventurous divers, the swim-through chimney known as "The Chimney" is an exciting feature. Entering the rock at around 20 meters, divers can exit at either 15 or 10 meters, encountering glassfish, boxer shrimps, moray eels, and other fascinating marine life along the way.
Even if you don’t SCUBA dive, Mu Ko Ang Thong National Marine Park is an incredible destination worth exploring.
