Koh Tao has a very simple identity: it is the place where more people learn to dive than anywhere else on earth. This is not a claim made by the tourist board — it is a function of simple arithmetic. Warm water (29°C year-round), excellent visibility (15–30 metres at the main training sites), shallow sheltered bays ideal for certification dives, a PADI Open Water course price (USD 250–350) that is roughly half what you'd pay anywhere in Europe or Australia, and 40+ dive schools competing for your business have made Koh Tao the most efficient place on the planet to get underwater qualifications. The island is also, separately from all of this, genuinely enjoyable — a small (21 sq km), green, unpretentious place with good food, a low-key nightlife, and beaches that are not spectacular by Thai standards but perfectly fine by anyone else's. Non-divers enjoy it too, but the diving is the point.
Diving in Koh Tao 2026
The diving around Koh Tao is genuinely excellent - warm (29°C), clear (15-30 metre visibility), and teeming with marine life. Resident whale sharks are the headline act, appearing most reliably between March and September. Chumphon Pinnacle is the most dramatic dive site - a series of submerged granite pinnacles covered in corals, with regular whale shark and barracuda sightings. HTMS Sattakut, a deliberately sunk naval vessel, hosts huge schools of batfish and resident turtles. Book your Koh Tao PADI Open Water certification or fun dive package through Klook - Klook lists all major dive schools with verified reviews and competitive certification prices.
Best Beaches in Koh Tao 2026
Sairee Beach on the west coast is the main hub - a 1.5km stretch of white sand with beach bars, dive shops, restaurants, and the island's best nightlife. For quieter swimming, Mango Bay on the north coast is accessible only by kayak or longtail boat, and is one of the most beautiful secluded beaches in the Gulf. Book a Koh Tao snorkelling and beach-hopping boat trip to access the island's most beautiful and secluded bays.
Where to Stay in Koh Tao 2026
Koh Tao's accommodation has evolved significantly - the budget bungalow era is complemented by a growing collection of boutique resorts and hillside villa complexes. Koh Tao Cabana on Sairee Beach offers the best combination of location, quality, and value. For complete seclusion, the Jamahkiri Resort & Spa on the south-east coast is hidden in a private cove. Arrange your Koh Tao island transfer from the mainland or Koh Samui through Klook.
