What an incredible and enriching experience! I stayed at Hydronauts for five days to achieve one of my goals: Open Water. From word of mouth, this center has an excellent reputation on the island and I can see why. The training is given in small groups, with particular attention paid to each individual's pace. Here, the team takes care to share their common love of diving. I had a unique experience in the water, with magnificent fish, coral and submerged structures. I felt safe throughout the four dives. The instructor, Steven, is attentive, enthusiastic and passionate. Thanks to him and my little team for all the moments we shared.

Definitely one of the best scuba diving schools I’ve ever been with! My boyfriend did his Open Water 20 with Gareth whilst I did my refresher course with Axel. I was quite nervous to go diving again after 9 years of not doing it. Axel was the perfect instructor for me! Very well trained, a fun personality, absolutely patient and encouraging, he gave me all the time I needed and answered all my questions. After my refresher I went on two fun dives with him that were absolutely amazing. He always made me feel safe and secure and we had a lot of fun. Thank you so much again for this! I enjoyed diving so much that I went on another three fun dives after my boyfriend was certified. Two of them with Shaq who was a lovely and fun dive master and one awesome night dive with Gareth who was also an amazing instructor! The whole team is fantastic and sparks good vibes only from the moment you enter the shop. Cannot thank you guys enough for everything. It’s not a goodbye for now it’s a see you next time. We will be back for sure.

Visited Hydronauts after recently gaining our open water certs. Absolutely loved the relaxed/ friendly approach of the staff and Ben, our dive master, was so calming and down to earth. Everything was made so easy during the dive and we felt very looked after. The cost of the dives were very reasonable and we had a fantastic time. If you're unsure where to dive in Koh Tao look no further !

From my first email, inquiring about diving and accommodation, the team at Hydronauts were outstanding. I had A LOT of questions and each was answered knowledgeably and promptly. I wasn’t a very good student at the beginning. My instructor, George, was incredibly patient and he and the office crew came up with a plan to help me get the best experience and training. What could have been the end of my curiosity in diving quickly turned into spurring a new passion. I’ll forever be grateful to George and the whole team and looking so forward to diving at Hydronauts again as soon as possible! My room was comfortable and the whole vibe of the place was relaxing and fun. The restaurants and bar onsite never disappointed, was always clean, food and drink always incredible and fantastic service.

I completed my Dive Master at Hydronauts, and it's the best thing that could have happened to me. I came from another dive center, almost finishing my dive master, and at Hydronauts, I realized I hadn't learned anything. Thanks to them, I've become a professional. What can I say about them? They were fully committed to teaching me everything I didn't know, with patience and a great vibe. I 100% recommend this center for all types of courses, from Open Water to the most technical and advanced ones. You will live a unique experience, professionalism, camaraderie, and fun.
