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

Just did my open water diving course at big blue and honestly had the best time ever. Big blue was great value (cheapest in koh Tao) and the staff were amazing. Accommodation is included when you dive and they offer half price accomodation before or after your dive. The atmosphere at big blue is welcoming and very social with a... 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! 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

I originally went to Koh Tao towards the end of January to start off my Southeast Asia trip, and spent a week on the island not diving(shocking!) In that short week I met tons of fantastic people at various dive shops, but none made impressions on me like the people I met from Big Blue. Further along, somewhere in Laos,... More
