Thailand's diving school island – affordable diving courses, resident turtles and the Nang Yuan sandbank

The offer data was updated on October 28, 2026.

About Koh Tao

Koh Tao is one of the world's most popular destinations for diving courses, and the island is entirely geared towards this: Dozens of dive schools line Sairee Beach and Mae Haad, courses cost about half of what they do in most other countries, and social life revolves around sunset beers after a dive. The diving conditions themselves are truly excellent for an island offering diving courses: Green and hawksbill sea turtles inhabit the island, blacktip reef sharks frequent the shallow waters of Shark Bay, and impressive dive sites like Chumphon Pinnacle attract whale sharks during the season.

Above the waterline, the island appears small, steep, and more beautiful than one might expect. Koh Nang Yuan (three islets connected by a photogenic sandbar) lies just off the coast, the bays on the east coast (Tanote, Ao Leuk) invite undisturbed snorkeling right from the beach, and viewpoints like John-Suwan reward the strenuous climb. Even non-divers will find something to enjoy here, but the island's rhythm is dictated by diving courses and recreational dives: early boat departures, logbooks at lunch, and a young, international crowd exchanging dive stories over dinner.

    Frequently asked questions about Koh Tao

    Most travelers choose the Lomprayah route: bus or night train from Bangkok to Chumphon, then catamaran (1.5–2 hours). Further north along the island chain, ferries run several times a day from Koh Samui (approx. 1.5–2 hours) and Koh Phangan (approx. 1 hour). From late October to December, the sea is rough, and crossings can be very unpleasant or canceled during this period.

    An SSI or PADI Open Water Diver course costs approximately 11,000–12,500 baht and lasts three to four days. Many dive centers offer accommodation included or at a discounted rate. Introductory dives cost around 800–1,200 baht each, and are cheaper in groups. Dive centers tend to differ more in class size and boat comfort than in price. Therefore, when choosing a dive center, pay more attention to reviews and the student-to-instructor ratio than to price.

    Yes, with slightly adjusted expectations: It's a small, steep island whose best beaches (apart from Sairee) are small bays. Snorkeling is best in the Gulf directly from the beach, Koh Nang Yuan is a classic half-day excursion, and the hikes to the viewpoints are excellent. For those seeking long stretches of beach and a wide selection of resorts, I would recommend Samui or Phangan instead.

    The best time for diving is roughly from March to September, with April to June offering ideal conditions of calm seas and visibility exceeding 20 meters. Whale sharks can be spotted any month, but are most frequently seen between February and September. The monsoon season, from October to December, brings high waves and strong currents, often leading to canceled dive trips. While many dive centers continue to offer courses, this is the least favorable period for planning a diving holiday.

    Koh Tao is ideal for learning to dive and offers the best snorkeling spots in the Gulf of Mexico, while Koh Samui impresses with its comfort, an airport, and long beaches. The speedboat ride between the two islands takes 1.5 to 2 hours, so many excursions include both. My comparison of Koh Samui and Koh Tao goes into detail on each category.
