Staff was so kindPosted on H PTrustindex verifies that the original source of the review is Google. I got my free diving level 1 certificate from Big Bubble. Our teacher was Ter; he’s an experienced professional—intelligent, incredibly patient, super gentle, encouraging, in a word, a great, great teacher! His instruction was clear and easy, so I was able to overcome my fear of sea and pass the exam. I highly recommend Big Bubble for anyone who wants to learn diving. FYI, the south sea area in Koh Tao is quiet and calm. Come to south.

PADI Open Water, Kho Tao – Our Open Water Dive instructor, Dyan, was so friendly and patient with us novices. Small class meant we got lots of attention. I was also impressed with the diving school… read more for other reasons. Firstly, it is one of the only Thai owned and run dive school and has been established for 30 years. Secondly, their beach access and bar with basic bubble bungalow accommodation across the road made the whole experience more enjoyable.

Best Diving School – Best diving instructor – This was such a great experience, I had the best time with the best instructor, ICE, who made me feel very comfortable and safe. Everything was done in a very… read more safe way. Everything about the dive was reviewed first by my partner instructor ICE. It is a smaller diving school in a small town and this means that there are far fewer people who sign up than in the big cities. This makes it a cozy relaxed atmosphere with plenty of space on the boat. My biggest recommendation to the diving school, instructor ICE, as well as his colleagues. I will definitely return.
