Western Gulf Islands
From Koh Tao to Koh Phangan and Koh Samui, the islands of the Western Gulf of Thailand offer wonderful diving conditions, with vibrant reefs and whale sharks.
Diving in Thailand offers a diverse and captivating underwater experience, making it a premier destination for divers worldwide. The country's diving scene is largely centered around the Andaman Sea, particularly on the eastern coast, where crystal-clear, warm waters reveal vibrant reefs teeming with hard and soft corals. These underwater gardens are havens for marine life, from the majestic whale sharks and graceful manta rays to the charismatic napoleon wrasse. Thailand's rich marine biodiversity is complemented by its strong culture of hospitality, welcoming divers of all skill levels to explore its aquatic wonders.
Liveaboard diving is particularly popular, especially around the Similan and Surin Islands, which are renowned for their remote locations and nutrient-rich currents that attract a myriad of marine species. These islands offer some of the best diving spots in the region, with both short and extended liveaboard trips available. For those with limited time, day trips to the Similan Islands provide a glimpse into the vibrant underwater world. Further south, islands like Koh Samui and Koh Tao have become bustling dive hubs, perfect for beginners and backpacking diving enthusiasts seeking a blend of community spirit and exceptional diving opportunities. Here, the competitive dive industry ensures high-quality courses at attractive prices, making Thailand a top choice for both novice and experienced divers alike.
Many divers flock to Thailand for the chance to see larger pelagics such a colossal whalesharks and manta rays which pass by the rocky outcrops further out to sea. These majestic creatures are most common in the areas around the Similans and further north in the Surin Islands.
Closer to shore divers will find that even walking off the beach, a coral encrusted sea floor filled with colour awaits. Brightly spotted octopus, napoleon wrasse and cheeky trigger fish can be found all over Thailand’s reefs and wreck as well as shoals of barracuda and legions of turtles. Critters are everywhere around filling every nook and cranny of the coral reefs pipefish, seahorses, eels and brightly coloured shrimp can be found by eagle eyed divers all over Thailand.
For shark lovers the most common types found in Thailand are black and white tip reef sharks who can be found circling around the reefs during the day and hunting during night dives. Leopard and guitar sharks, although a little rarer than reef sharks can also be found and are excellent subjects for underwater photographers
