Fabulous day with BB divers. All crew were friendly, professional and helpful. The snorkeling was way better than expected. Marine life was abundant. We dived at three sites with perfect visibility. Drinks and Thai food provided were tasty. Pickup and drop off service was timely. Highly recommend this not-to-missed activity while visiting Koh Chang.

Today we had a wonderful snorkel day with BB Diving. There was even a prescription mask for my son! After the briefing by Boatmaster Oscar we visited three beautiful dive sites. Lots of fishing and clear vision. Lunch was delicious (Thai food) and there was plenty of drink and fruit. In short, highly recommended!

Very enjoyable trip totally worth the money. The staff was super helpful. They were so good in fact that one of our party lost her phone. The boat had to move on, but they sent a boat back to look for it and found her phone and then refused to take a reward. Although I did finally get them to relent. Markus was really great and very personable. The food was actually also good all the way around a super experience.

We had a wonderful time with BB Divers! Oscar & the crew were very hospitable. Oscar was super knowledgeable about the snorkel spots and seemed to take seriously safety both for the reefs and people. One note, because it’s dangerous for the coral reef to put on sunscreen right before diving, perhaps there could be an earlier reminder so the tour is less damaging to the coral.

Big thanks to Oscar and the crew on Big Boat for a perfect day of snorkeling. The boat was large and shady, the food was tasty, and the communication was on point. Oscar gave very clear instructions and set great timing expectations as well as telling us what to look for in the reefs which were amazing. The entire trip exceeded my expectations which were pretty high since ive been waiting my whole life to see this. Definitely book this excursion!
