  • "Amazing facility, amazing people. The guys are real professionals and really funny in the same time also which makes everything perfect. Super flexible and amazingly helpful. Highly recommend them to anyone who wants to do any type of dives from recreational up to tech dives around the island." - Tovari

  • "I did with Koh Tao Divers half-day refreshing course, night dive and 7 fun dives. All members off staff are nice, helpful, relaxed, happy to guide you and also very safety orientated. I have dived with 10+ dive operators in 5 continents and this one was definently number one so far."

" The boat is really good, schedule covers a wide variety of the best sites, they have good equipment but what makes this diveshop stand out is the atmosphere that I haven't experienced elsewhere in Koh Tao. The fun dives are literally fun dives. I have never felt so relaxed diving, being encouraged and enjoying myself. Everyone working at KTD goes the extra mile to make sure all customer wishes and needs are accommodated. When on board I felt like being part of the crew, fully involved in discussions about the dives, about the marine life and this created an environment where it was just so easy to bond with the other divers as well. I had 13 fun dives with KTD, namely with Giorgio, Tom, Pauliina, Eeva & Antti who were all excellent, knowledgeable and super fun and really hope I can go back again soon. And of course the cherry on top was the Sail Rock excursion where I could swim with a baby whale shark!"
