We stayed in Koh Tao for 10 days and spent all of those diving at least once (often twice) a day with Big Blue diving as well as stayed at their hotel just up the street. We had an amazing time! We are on a world trip (www.chasethesummer.com for pics) and are 4 months in now and my husband and... More

I finished my dive at big blue just over a week ago and I am still reminiscing! I can honestly say it is one of the best experiences of my life. Me and my friends were instantly made to feel welcome and our accomodation was much better than we had ever hoped. The staff are all really efficient and professional... More

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

Me and my friend went to Koh Tao on our holiday. Before we got there we did online check and send them email regarding some additional info - they did respond quickly and in great detail. After we settled on monday morning we booked the dives for the afternoon. When we went on the first two dives we were lucky... 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!

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.
