Big Blue Diving is exactly what they say they are, plus the friendliest, most helpful staff. I did one of their online packages to get my Advanced Open Water + 10 fun dives, and it was the best value diving I've ever done or even heard of for the amateur diver. The on-site hostel is pleasant, the dive masters are all great leaders, the instructors really know their stuff. The restaurant has good food (tho a little pricey), the dive boats are nice and comfortable for the half day trips they do multiple times each day. I dove with 6 different dive masters and instructors in my 15 dives, and they were all super. I recommend Big Blue to everyone who goes to Thailand, whether they were planning on going diving or not!

I did mz OWD and the AD and both experiences were great. The teachers took much time to help all of the course. And if you had more problems than the rest of the group the teacher helped you as long as you needed. But for the rest of the course it wasn’t boring. So I felt really well during th OWDd and the AD. Can only recommend!

the best thing about our trip to thailand was big blue diving! The instructor was so great jacqui crawford

If I had the vacation time I’d be back at big blue in a heart beat. What was supposed to be 3 days turned into a week and even then I didn’t want to leave. Loved everything about it and wish I could go back. And we saw a whale shark so that topped the whole trip off.

When I first arrived at Big Blue it seemed as if everyone had already known each other for years. The atmosphere there was amazing and the people that I have met were some of the fondest friends I have made in half a year of traveling. I had such a great time diving and felt at home immediately. I would recommend Big Blue to everyone who is looking for a place with great people who like a drink and have a passion for diving (and a party now and then). The beds are absolutely awful though, expect to come home with a great tan and a broken back ;)

I can't thank enough the whole team but especially Ernesto who truly hook us into diving! I am now travelling the world searching for new diving spots but it was there in Koh Tao that I realised how much I love the sea and its creatures!

I did my OW and AA course with Big Blue and it was the best decision I could have taken. Not only because diving is amazing, but the enviroment inside the school and among the team is incredible.

Beginning of September I had the chance to make my first diving with Sonia, a great diving master. Although it was the first time I felt like I was a veteran thanks to the tranquility and confidence that Sonia was able to instill in me in only a couple of hour of lesson before the diving session. Definitely highly suggested!
No need to say anything about the location: absolutely amazing!

Big Blue Diving is an amazing place with great staff that will help you with everything. The perfect place to make a l ot of new friends and have a good time! It's heaven on earth!

Wouldn't recommend any other company. Had a great experience learning with these guys. Was recommended by a friend. I will come back for more dives.

I got my scuba license at Big Blue and then stuck around to do another 2-day/higher level certification because it was so much fun and the instructor (Simon) was so great. Can't recommend this place highly enough, hope to make it back real soon!

I was absolutely terrified of the ocean until I arrived at Big Blue, Ooh Tao. Where my instructor changed my fear of open water into a deep passion for the ocean.

I learned to dive (open water and advanced) with Big Blue 2 years ago and felt it was a wonderful and safe company. The guys were fun and welcoming . My friends who are very experienced divers wanted to try thailand so I suggested Big Blue. We had the most amazing 9 days. We completed 20 dives including a night dive. Staff were amazing. In fact so much we've booked to go again in March 2019

I liked the whole atmosphere around Big Blue. They combine great fun with save and professional diving.

My partner and I knew we wanted to dive and we heard Koh Tao was a great place to learn. After lots of research and chats with a few companies we decided to go for Big Blue. We believe they had an excellent balance of professionalism and friendliness. Anyone we spoke with from the office staff, people at reception, any staff in the cafe and of course our wonderful instructor Phil, were all very knowledgeable and helpful. The actual diving experience was amazing, both my partner and i had different reservations and fears to over come but our instructor was patient and knew exactly how to help us. We had such a great experience we decided to book on to our advanced course straight away after. The whole area had a great vibe and we easily made lots of friends. We traveled for 8 months in different countries but our diving experience with Big Blue was easily one of our top moments.
