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.

    Open Water Diver

    Open Water Diver

    If you're curious about scuba diving but want something more meaningful than a one-day experience, the Open Water Diver course is the ultimate way to truly try scuba diving in Phuket. Designed for complete beginners, this course introduces you to the underwater world step-by-step — giving you the chance to learn real diving skills while safely exploring the ocean for the first time. No previous experience is required. Your journey begins with simple online learning that explains how scuba equipment works, how to breathe underwater comfortably, and the key safety principles every diver should understand. This allows you to learn at your own pace before entering the water. Next, you’ll move into confined water training where your instructor will guide you through essential skills such as buoyancy control, regulator use, and underwater communication in a calm, controlled environment. Once you're comfortable, it’s time for the most exciting part — your first open water dives in the ocean. Over multiple dives, you’ll practice what you’ve learned while discovering Phuket’s marine life and developing confidence underwater. The course typically takes around three days to complete and includes both theory and practical training dives. By the end, you’ll not only have experienced scuba diving — you’ll have gained the skills to dive safely to depths of up to 18 metres anywhere in the world. This makes it perfect for anyone who wants to move beyond just “trying” diving and instead start a lifelong adventure. If you’ve ever dreamed of exploring the underwater world, this is your chance to turn curiosity into confidence — and your first breath underwater into a globally recognised diving certification.

This refresher program gives you the opportunity to review and practice the key skills you learned during your Open Water Diver training, all under the guidance of an experienced SSI Professional. In a relaxed and supportive environment, you’ll revisit essential techniques such as buoyancy control, regulator recovery, mask clearing, and general dive safety procedures. It’s the perfect option to take before a dive holiday, allowing you to rebuild confidence before heading out on fun dives. Instead of worrying about your abilities, you’ll be able to fully relax and focus on enjoying the experience — and the incredible marine life around you. The Scuba Skills Update is also ideal for students who have not yet completed their Open Water certification. If you’re a non-certified diver preparing for your open water training dives, this session provides valuable extra practice to help you feel fully prepared.

    Top Wildlife Sightings in Thailand

    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
