Came for fun dives, left with my AOW cert. 🤣 Everything was so much fun and everyone there was super friendly and supportive. Big thanks to Kru.Nui & Kru.Mew for taking care of me during the fun dives, and a special thanks to Kru.Champ for guiding and supporting me all the way through my course. You guys are amazing 🤙🏻💯 Had the best time at BigBubble 🫧🦑🫧 10/10 would recommend kaaaPosted on mahasan koetkhlaiTrustindex verifies that the original source of the review is Google. This was my first time doing the Open Water diving course. I decided to try it because I wanted to experience and my friend invited me. Instructor Joe was really good—very patient, calm, and always trying to guide and encourage me through every skill. The food was great, the accommodation was nice, and all the staff were friendly and welcoming. See you again on the next course!Posted on Nam NiTrustindex verifies that the original source of the review is Google. เกือบหลับแต่กลับมาได้ ครูโจ้ใจเย็นขั้นสุด ความรู้แน่นๆๆๆจุกๆPosted on Preeyachat RONGKAEWTrustindex verifies that the original source of the review is Google. 🤿🤿🤿Posted on juntae w.montreeTrustindex verifies that the original source of the review is Google. This is a dive company I truly love. I’ve heard they’ve been around for over 30 years, and from the first day, I felt I could trust them. Honestly, I chose this shop based on a recommendation—and it turned out to be one of the best decisions. The past few days felt like stepping into another world. Being underwater… it’s like discovering another part of myself. I didn’t expect it to be this powerful. My instructor, cham, was amazing. Very skilled, calm, and clear in his teaching. He always made sure we were on the same page, which made everything feel safe and easy to understand. I’m really grateful to learn from him. I’m proud to be part of this journey with Big Bubble Koh Tao. Thank you for such an unforgettable experience. I’ll definitely be back for my Advanced course. And of course, if anyone is looking for this kind of experience—I highly recommend Big Bubble. See you again soon. 🌊Posted on Nick HansenTrustindex verifies that the original source of the review is Google. Fantastisk oplevelse at ta dykkercertifikat hos Big Bubble Diving, det var en tryg oplevelse i vandet med en super dygtig instruktør som var meget god til at forklare så man forstod det første gang maks 4 elever pr hold, dog var jeg heldig at være alene på holdet under den teoretiske del, alt i alt en fantastisk oplevelse kan klart anbefales😊Posted on BaranTrustindex verifies that the original source of the review is Google.

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.
