I loved this school. They are professional and fun and our instructor really knew her stuff. The dorms and bathrooms at the school is also comfortable and clean and the food is amazing.

Don’t think twice about coming to Big Blue. The atmosphere and the people there are one of the best on the whole island. Definitely recommend Big Blue.

I stayed at Big Blue for 4 days a got my OWD there. It was by far the best decision of my vacation - beautiful place, friendly staff, good price, amazing divesites. Big Blue is the main reason why I want to get bet to Koh Tao.

I was recommended this company by a friend and i’ll recommend it to everyone I speak to! Very professional but a good laugh. Felt safe and during the open water certification course they taught you so well but also gave you the confidence and chance to do things yourself. My instruction was called Neil, he was amazing. Everyone very friendly, all the other instructors would talk to you and smile. Can’t fault it.

Big Blue diving changed my life! I had never even had an interest in diving until I walked into Big Blue. The people, the atmosphere and of course the location made me fall in love with diving. The entire team of staff are so knowledgeable, passionate and caring, that it makes the place feel like home. I would (and have been) recommending Big Blue to anyone and everyone!

I would highly recommend the Open Water course at Big Blue. The instructor Neil was really professional and made sure we were all progressing through the course organically and that we actually learned what we needed to dive independently. His diving assistant Yuri was also on the case and was also there to ensure we had the right support and level of information needed at any one time.

Paid for two dives in two different sites, but ended up doing kind of one and a half dive in the same site, due to the withdrawal of the other couple diving with us, during the "skills dive". The site of the diving also had poor visibility conditions and was very close to the shore, so we basicaly ended up seeing pretty much what we had already seen during snorkeling. Also paid extra for photographs and they weren't very nice (maybe partly because of the poor visibility).
The upside was that the instructor and the crew were all very nice to us and the equipments conditions seemed to be very good too, so we felt safe the entire time.
However the overall experience was kind of disapointing.

I was so lucky to have the amazing ste as my dive instructor. He made the whole experience easy and fun.

Very professional, vibrant and friendly staff. Couldn’t ask for better.
Felt very safe from start to finish
My first dive at 68 years old
Would love to do it again. Just loved Big Blue.

A friend and I signed up for this on a whim and it was one of the best decisions we made on our trip!

You can tell these Big Blue really cares about what your safety and learning and have a passion for it, because by the time you're done your diving course, it completely rubs off on you.

Their staff are amazing people, their courses are easy to follow, and the instructors take care to make sure you've got a hold of things, in and out of the water. A huge shout out to the best instructor there, Yam - he is seriously the best and made my experience 100x better.

Highly recommended for taking your padi certification here.

Had the greatest time ever learning to dive there our instructor Rachael was amazing helping us making sure we understood everything and made it so fun along the way. After being trained at big blue we went to another dive school for a fun dive and that shown just how good big blue is compared to other places x.

Everything's perfect: team, equipment, location.
I might come back one day to pursue my training !!

Did my Dive Master Training here. Best dive school on Koh tao and so friendly, met a load of friends and can’t wait to get back out to do my tech stuff

Big Blue gave me a new passion. All the staff is awesome. I really enjoyed my time there. If you didn’t went to Big Blue Diving, you didn’t went to Koh Tao Island. Special thank to Charlotte who was my Scuba diver master. She was awesome!

Thank you for everything!

Koh Tao was very nice and learning how to dive was an unforgettable experience. My instructor was like a drill sargent though so it put a lot of extra stress on me that I was not thrilled with. I ended up ending my class and started working with another instructor because I could not handle the constant yelling and pressure that he placed upon us.

I am frome switzerland and I made the SSI-AA and the "Nitrox" Course by big blue in March 2019.
Everything was exclent and I can highly recommend that shool for diving. They refill the tank on the boat so I never had to carry heavy tanks. The staff was friendly and the diving instructors are very competently.
I had a lot of fun to dive with big blue!
My english is not very good, so I sometimes had to Interrupt the instructor when he explane something. That was never a Problem and finaly I always undersand what he say and follow the instruction. Germann speaking Person: tray to learn all in english, it will be much easyer to dive later on any place on earth!
Thanks to the big blue diving Team and see you soon

My wife and i came to Big Blue to get our Open Water certification. With a fear of sharks, the deep unknown, and the general awkwardness of trying to breath underwater, we decided to pay the little extra and take private instruction. We were paired with Gus and had him throughout the next few days. It was awesome! Gus has a way with people and is such a great instructor, and genuine guy. He has many hours of experience and knows how to get you over your obstacles and will help you conquer your fears. His love for the ocean and diving is infectious and thats just what a student needs to see. So if you have a dream of diving, ever considered diving, or are unsure about diving but think you might be interested, call Big Blue and let Gus introduce you to a underwater world that will blow your mind. Thank you Gus for the wonderful instruction and taking us through our OW course. We are looking forward to our Advanced OW!

recently I did my open water certificate and attempted some fun dives after. Great school, teaching staff and dive masters. Excellent place to get started. I would highly recommend to anyone.

everything was just perfect ! I would do my Open Water course again with Big Blue.
Only thing I didn't like, 5% fee if you pay with credit card....

Super team and amazing dive sites, Koh Tao island is definitely heaven for divers and Big Blue the perfect club to enjoy !

Great place to get my feet wet for the first time in fins.
High quality, high class, good company.

I only did the basic diving package, I had Julie as my instructor, she was a wealth of information and very professional, I would highly recommend her. A++ establishment

I signed up to the SSI Open Water course after reading reviews & being recommended, I wasn’t sorry! It was the most exciting experience I’ve ever had & I felt so safe.

My instructor, Graeme was extremely patient, informative & efficient. I had some issues with getting out of the water with my BC & tank, it’s pretty heavy for a first timer, and a petite one at that lol. It wasn’t an issue. Graeme & the other instructors immediately helped me & as I was pretty embarrassed, they also reassured me. On next few dives, with my new found confidence & strength & under Graeme’s watchful eye, I had no problems at all.

I enjoyed my OW so much, myself & the other 3 in my group all signed up to the Advanced Course straight away which was even more fantastic. Amazing dives, good visibility & I felt completely safe.

The equipment is well maintained & all the staff in the office to the restaurant to the instructors are professional & friendly. It’s a really great vibe.

I loved my experience so much, I’m due to fly back in a couple of weeks to continue diving with Big Blue & hopefully take my diving up to the next level!

Lerned a lot on the courses and on the ca 40 dives I have done. Top place in every respect. Last time I payed 300 baht for a nice bed pr night, shareing room with another diver. Top fundiving, and learning a lot
