Koh Tao Divers - KTD

Koh Tao Divers (KTD) is a well-established diving operation located on Haad Sairee, the main beach strip on the western coast of Koh Tao. The island is widely recognised as one of Southeast Asia's premier destinations for learning to dive, thanks to its clear waters, accessible reef sites, and relatively calm conditions — and KTD sits at the heart of that scene. The centre caters to a broad range of experience levels, from complete beginners working toward their Open Water certification to more advanced divers looking to log dives at the island's varied sites. Visitors can expect a professional, structured environment with an emphasis on safety and small-group instruction. The centre's strong and consistent reputation, built across hundreds of visitor reviews, points to attentive instructors, well-maintained equipment, and a welcoming atmosphere that suits solo travellers and groups alike. English-language instruction is standard at centres of this type on Koh Tao. Good to know: KTD is open seven days a week from 09:00 to 18:00, making it straightforward to walk in and enquire, though booking in advance is strongly recommended during the busy high season months of December through April and again around July and August. The centre's website at kohtaodivers.com provides course details, pricing, and contact options. Those planning a dive course should budget several days on the island to complete the required theory, pool, and open-water sessions comfortably.
