The diving place is full with good teachers. Don't be afraid just try it out!Posted on Tom JTrustindex verifies that the original source of the review is Google. Had a few absolutely beautiful dives at Big Bubble! I did my PADI license here at 22 years ago. The dive center has changed a lot since then. It has grown, everything has gotten even better in terms of organization and all the staff are amazing: professional, helpful, ready to assist with any help one might need before the dive or on the boat. This dive center is probably the best on Koh Tao. 100% recommendation!Posted on Sunday ArthitayaTrustindex verifies that the original source of the review is Google. สนุกดีค่ะ ครูใจเย็นPosted on Note NajaTrustindex verifies that the original source of the review is Google. แนะนำเลยครับ สำหรับคนที่กำลังหาที่เรียนดำน้ำ จุดที่เรียนดำน้ำปลอดภัยและสวยมากกกกก ปลา ประการัง เยอะมากครับ สอนดี เข้าใจง่ายและลงดำจริง การสอน 10/10 สถานที่เรียน 10/10Posted on ผิงอัน ผู้จัดการ Allianz AyudhyaTrustindex verifies that the original source of the review is Google. ครูสอนดีมากค่ะ เข้าใจนักเรียนที่เพิ่งเคยมาเรียนครั้งแรก 🥰 แนะนำเลยค่ะ คอร์ส Open water เกาะเต่า ต้องที่นี่เท่านั้น 🫶🏻Posted on Mags K.Trustindex verifies that the original source of the review is Google. I signed up for the Open Water course (including accommodation and breakfast) with Big Bubble, and it was one of the best decisions I’ve ever made. My dive instructor, Champ, was one of the most patient, understanding, and professional instructors I could have asked for. He was incredibly patient and caring throughout every step of the course, both on the surface and underwater. At one point, I almost quit because I felt unexpectedly anxious. But Champ stayed calm, reassured me, and helped me believe that I was safe and capable. Just had to breathe. I wouldn’t have accomplished this without Champ and my fellow trip mates. Most of the staff were very friendly and attentive, especially instructor Champ and Nui. Their support made the whole experience even more special. I’ll definitely be back for the Advanced course. Thank you for such an unforgettable experience. Love you all! 🤙🏾🩵Posted on ירדןTrustindex verifies that the original source of the review is Google. Had an amazing experience returning to diving after a long break! The team was super professional and patient. Huge thanks to Mew and Dian for being such great guides and showing us the best spots. Seeing a whale shark was the cherry on top! Highly recommended! 🦈✨Posted on Alexia PattersonTrustindex verifies that the original source of the review is Google. Got my dive certificate here 2 years ago and came back for some fun dives. Really great staff who are fun to dive with!

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.

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!
