Uno de los mejores, sino el mejor dive center en la isla. Cuenta con una gamas de profesionales excelentes, las instalaciones son de primer nivel, 2 barcos de buceo sumamente cómodos, amplios y los mejores guías de la isla. También cuentan con apoyo de los Dive master que generalmente manejan más idiomas aparte del inglés para poder asistirte en lo que necesites. He pasado un mes haciendo mi dive master y ha sido increíble. Puedes hablar con ellos ya que cuentan con acomodación para transitar los días que necesites en la isla y poder terminar tus cursos. Es el dive center que más Dive Master certifica en la isla y probablemente a nivel global. Los caracteriza el profesionalismo y la diversión . Tienen viajes durante la semana a los Mejor puntos de buceo de la isla como; Southwest Pinnacle, Sail Rock, Chumphon, Sattakut wreck, 313 wreck, white Rock, Tweens, Japanese Gardens, Mango Bay entre otros. Los recomiendo 100%

I dove with David, for my Open Water Advance rating. He was hands down the most experienced dive master i've ever dove with (+/- 10,000 dives) he was professional, explained things well, and made the dives fun. Simple Life is the right choice for a great dive experience on Koh Tao.

I had an amazing experience learning to dive here. I came all the way from America and had the most amazing dive instructors Alice and Young Master Dylan. They were so patient, supportive, and I felt so safe learning from them. I cannot put into words how much fun I had and how amazing my instructors were. Shout out Alice, Young Master Dylan, Cam, and jose.

Commitment to Coral Conservation

Alongside running dive tours and PADI Courses, Simple Life Divers has launched a coral reef restoration project in Koh Tao. Named ‘Alotmeant’, our team of divers saves damaged coral fragments and transplants them to create a new area of coral reef. Results so far have been amazing.

Diver Training Pool

Mastery of scuba skills is best-achieved in ideal conditions with respect to depth, water movement & visibility. This applies for both entry-level training & professional courses.

Though it may sometimes be possible to learn skills in the ocean, best is using a swimming pool as the initial training environment. For this reason, Simple Life Divers has invested in a two purpose built training pools at different depths.

Which months are best for diving in Koh Tao? 

Koh Tao offers excellent scuba diving throughout the year, although conditions are typically at their most challenging during the northeast monsoon, usually in November and sometimes extending into early December.

Situated in southern Thailand, tropical Koh Tao enjoys hot sunny weather all year round. Sea conditions in the Gulf of Thailand are typically calm, with water temperatures measuring between 27-29°C. Underwater visibility is good to excellent, with negligible currents around Koh Tao. We enjoy excellent scuba diving throughout the year.

Koh Tao Monsoon

If visiting Koh Tao to dive, avoid coming during November.
Koh Tao’s clement climate is punctuated by one exception. Monsoon!

Each November, monsoon season heralds strong winds, big waves and torrential rain, persisting for a couple of weeks. Lightning storms are spectacular. Diving becomes restricted to sites on the sheltered leeward side of the island & visibility underwater is reduced. If you prefer diving in crystal clear blue water, plan to visit Koh Tao outside of monsoon season.
