I stayed on Koh Tao with the folks at Big Blue diving in January, 2012. Easily one of my best experiences ever. I was new to the world of diving and signed up for their open water course. Our class was awesome and consisted of myself, a guy from the netherlands, and a couple from moscow. Our instructor was Neil,... More

In March I arrived at Koh Tao with my sister to go diving. We didn't know much about Koh Tao nor diving and initially ended up at Chrystal Divers at the beach near the pier. Although people were nice there and seemed very qualified, it looked a bit dull. So we decided to check out Big Blue at Sairee Beach... More

We were approached on the boat to koh Tao by big blue and after already hearing positive recommendations from friends we decided to take their free taxi and check it out for ourselves... And we're so glad we did! From the moment we arrived we were welcomed and treated with great professionalism, all our needs were met and more. They... More

Great Instructors, Awesome location! We completed our Open Water Course with 'Mama G', our instructor, and could not resist the temptation to get into the water for the SSI Advanced Adventurer Course completing 5 further dives, including a wreck, deep sea and night dive. We leave Koh Tao very satisfied and addicted to diving! More

I went from an absolute diving beginner to completing by ISS open water at Big Blue. The whole experience was perfect: excellent location, ultra-enthusiastic staff (I recommend Heather), very professional setup, simple accommodation, bar/hotel has a great atmosphere. Was my favourite diving place in Thailand. More

I've been diving all over the world for a number of years and i have to say that Big Blue are possibly the best operator i have dived with. Their staff are excellent in terms of maturity, professionalism and a sense of fun. Too many dive centers have a lot of very young instuctors and DMs running around enjoying themselves... More

Loved every minute I spent here! I got my open water certification here, and enjoyed it so much I immediately signed up for the advanced dive training. Their prices are super, their staff is very helpful, their instructors are amazing, and the other travelers you meet here will be awesome! (Oh and I saw a whale shark on half of... More
