As always, a super pleasant atmosphere and great planning at BBDivers. We dived at the T1 Wreck/Hin Raab and the HTMS Chang with Jo, our dive instructor. Jo was super competent as an instructor and we really enjoyed the dives with him! We come back every few years and are always happy to go diving with BBDivers!

We started with a great refresher lesson with our guide, Steve. He was very informative and helped us feel quite confident as we submerged. It was a wonderful experience and I would definitely recommend BB Divers to anyone interested in exploring Koh Rong National Park.

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.
