Everything was really well organized — from the pick-up at the pier to the stay at their bungalows, it was all smooth and easy ️. The staff were friendly and always ready to help. Totally worth it and such great value for money. Would definitely recommend this dive school and hope to come back for more dives soon! ”

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.

New diver, great experience with Devesh! – Spent about 5 days at Big Bubble Dive School doing my Open Water and Advanced Open Water courses and it was AMAZING! It was my first time and the instructor… read more (Devesh Saboo) was patient and a great teacher.
The school is very clean, everyone is friendly, and it even has a nice restaurant/bar with beachfront access in the back of the school.
One of the big reasons my experience here was so amazing was because of my instructor Devesh Saboo. He was not only friendly and welcoming, but his technical knowledge and experience diving was helpful for someone new like me. On top of that he also made us feel welcome by providing local recommendations and taking us to try good food. I really enjoyed the time I spent with him!
Everyone else that worked there was friendly and welcoming too. Yaya, JT and Pong were awesome!
Spending time with the staff and instructors was as great as the diving at all the beautiful locations!
