We booked a diving trip from Koh Chang with two dives and went as a family (2 adults, 2 children) with our dive guide Adrian. From the very beginning, everything was perfectly organized. Adrian selected the right equipment for us and explained the entire process in a clear and detailed way. We especially appreciated that we were allowed to assemble our own equipment. This was not only a great learning experience but also an important safety aspect, which many dive schools don’t emphasize enough. Adrian took plenty of time to explain everything and prepared us thoroughly. During the dives, he was attentive, calm, and highly professional at all times. We felt safe throughout and had two fantastic dives. Highly recommended!

Spent the day with family and friends at BB divers off the coast of Ko Chang. Our group of eight people ranged in age from 8 to 73 with different levels of experience. Some snorkeled, others did scuba for the first time, and three (including myself) took a refresher course which included two dives. Our instructor, Steve, was patient, knowledgeable, and very experienced. He made us feel at ease and confident in our abilities. The entire crew helpful, friendly, and professional. I would highly recommend.

A fantastic experience. Our Dive Master, Oscar, was very friendly and patient with us, always attentive to our needs and explained everything very well and very clear. We highly recommend diving with them because it is very comfortable and fun the boat ride and beautiful seabed we saw. In addition, we have a surprise that we loved: the friendly photographer Hanah. She was taking beautiful pictures of us throughout the day of diving that we could then buy. Thank you very much to her for her good work and thank you very much to Oscar, for making this dive a beautiful and unforgettable experience. Attentively Mary Jesus and Charles

We had an unforgettable family day! With two children who made their first dive under Adrien’s good care, the little ones feasted and so did the adults! Thank you to all the team who accompanied us, from the helpers on the boat, to the captain, the instructors, and Hanah the photographer who allowed us to leave with great shots. Perfect organization, very professional! Thank you to all!

I love diving with B.B this is my 4th year with them I am very lucky to have this pleasure. Kristen, Pawel and the staff in the office are extremely helpful. All the boat boys will help with what ever you need and are very friendly. Hannah the resident photographer is very friendly and takes some wonderful photos. Steve, Adrien, Ali, Delphine, Mr Pong, Patrick, Harry, Pierre, Oliver (sorry if I forgot anyone) are friendly, professional, knowledgeable and patient. I truly am blessed to be able to dive with this lovely team.

Absolutely fantastic experience of diving with BB Divers. From doing my refresher to seeing a baby Whale Shark I couldn't recommend more. Very highly skilled instructors, organised professional and just the best bunch of people you could wish for. I will certainly dive with them all again
