Koh Tao Divers - KTD

Koh Tao’s original dive center since 1987, KTD keeps things exactly how you want them underwater: calm, professional, and quietly confident. The shop sits right on Sairee Beach, a short flip‑flop stroll from the sand, with an easy check‑in and coffee before you board their boat. Days roll from briefing to blue water smoothly, with a focus on safety and clear, no‑stress teaching that lets you actually enjoy the reef. Whether you’re trying scuba for the first time, ticking off your Open Water or stepping into specialties, tech or even CCR, the team covers the full spectrum and does it well. Expect well‑run fun dives to Koh Tao’s greatest hits — coral gardens, pinnacles and the HTMS Sattakut wreck — with small groups that match experience levels. The vibe is chilled but dialed‑in; instructors know the currents, where the batfish hang, and when Chumphon Pinnacle lights up. Come by between 9am and 6pm any day to talk courses, gear up, or just ask what conditions are like this week. Being on Sairee means post‑dive sunsets are built in — rinse, grab a shake from the stand next door, and watch the longtails drift past while you log dives. If you care about quality and local know‑how over hype, KTD is the smart pick on Koh Tao.
