My boyfriend and I went fun diving with Hydronauts and had a great experience from start to finish. The entire team are very friendly, helpful and prioritise safety. We were very impressed by Katie and the office/shop team, who were well organised and able to provide information regarding our dives, such as dive site and weather conditions. Our instructor/guide Gary was amazing!! He is clearly passionate about diving and gave us lots of amazing briefings and information about the sites we visited. He ensured we were safe on the boat and underwater, and we had so much fun diving with him. We would recommend Hydronauts to anyone visiting the island for courses and fun diving, and will definitely be back again! (Hopefully sooner rather than later!) Also loved the bar for a Chang or Mojito after diving too!

A good little hotel in Koh Tao - my partner and I stayed here for 2 nights.
The rooms are comfy, clean and tidy. This hotel is perfectly set up for divers, so if that’s what you’re looking for then it’s perfect. We didn’t dive but still enjoyed our stay; however, it does mean that the pool is only for use when divers are not using it, and there are no sun beds so it’s not an area that you can relax/lounge around in. We also found it to be a bit noisy in the mornings and evening times.
Shark Bay and Freedom Beach are both within walking distance of the hotel, and are definitely worth a visit. Freedom Beach is best for sunbathing (and the cafe down there provided excellent food). Shark Bay is smaller but much better for snorkelling. We saw a turtle there on our last day!
If you stay here you absolutely MUST eat at the Barracuda restaurant on site - the food was absolutely SUPERB and some of the best that we had in Thailand!
We had both lunch and dinner there.

With plethora of dive shops in Tao it’s hard to stand out but Hydronauts did it for me. The crew that runs this place is very professional yet they immediately make you feel like you are part of a family. They are genuine diving enthusiasts and that enthusiasm is contagious. I made over 10 fun dives with them and they made my diving experience fun and educational at the same time. They were very responsive to my feedback and flexible with my schedule. The groups are small so you get enough personal attention. If you are looking for dive shop in Koh Tao check our Hydronauts. They were very responsive to my inquiries prior to my coming to Koh Tao what gave me a good feeling right from the beginning.
Bonus tip;) As opposed to traditional BCDs that most schools offer, Hydronauts offer wing style BCDs so if you ever wanted to try it out that would one more reason to dive with them.

We thank you very much for your review. We are happy that the extra time we make to separate ourselves from the competition didn't go unnoticed. It would our privilege to show you the amazing underwater world we have here on koh tao divers.
We hope to see you soon

Thinking of entering the world of technical diving and you want to learn from the best then look no further than Hydronauts, Koh Tao. It's the one stop dive school that you can learn everything from entry level diving to tech diving. I recently completed my Sidemount & Deco 40 courses and had the pleasure of being taught by Erik Brown aka Master Chief. After our first brief on day one I knew going into the courses that I was going to be taught by the best and this was confirmed throughout the time I spent completing them. Highly professional, hugely experienced and most importantly conducted in a safe and controlled manner I could not be happier that I chose Erik and the team (Derek, Liz, LJ etc.) at Hydronauts on entering the technical world of diving. First class service along with amazing equipment made the whole experience truly memorable and I look forward to continuing my learning with these guys!!!!
Thank you Master Chief and all the team @ Hydronauts

Thank you for your incredible review Dave.
As the founder of Hydronauts, Erik is a legend and inspires us all to be excellent underwater.
It was a pleasure to watch you progress into a competent tec diver and I look forward to diving with you when we start running trips to the Torpedo and Unicorn wrecks!

The most memorable part of my visit to Hydronauts are the facilities. They have 3 teaching rooms, their own teaching pool and experienced instructors. One of our party took on the 3 day fully insured course and said it was the best thing he has ever done. From several others in our group we heard only glowing reports about the patience and simple instructions given when they undertook a try dive 'experience'. On this occasion I did not participate but I will be certainly having a go on my next visit.

I stayed and dived with Hydronauts over four fantastic nights and loved every minute of it. This beachfront property has excellent equipment, wonderfully friendly and experienced instructors, and some of the best vibes in all of Thailand. If you ever want to try scuba diving on Koh Tao this is THE place to go.

Was introduced to the Hydronauts team through my uni mate and was originally planning to stay for a 3 week visit. However, I decided the projects happening there, the ethos of the relocated resort and the second to none training I recieved made it an easy decision of staying on the island and diving with these absolute legends, and started my divemaster training with them recently🤙 The team moved to the resort 2 just weeks prior so work was getting done to the quality standard it has reached now. I was diving in brand new gear and the instructors have been top notch on getting me up to speed and making the most of the absolutely cracking trips they have taken me on! This resort and my personal experience with the staff helped me settle into life on the island, I was greeted with a sense of belonging and felt like I was part of the family! 10/10 experience so far, it has been hydronaughty 🤙🤙🤙

Liz provided my daughter and I with excellent guidance on our “Try Dive” around Nang Yuan. It was a wonderful experience that we will always remember. I highly recommend Hydronauts and Liz in particular. She was very patient, thorough and professional.

If you want to get your diving licens and know what you are doing you should go to hydronauts to get an amazing experience!

This is a very professional dive shop on koh Tao. They teach everything from discovery scuba to technical diving. They have very nice gear for sale at really good prices and the staff is amazing. Our friend Eric is very professional and I strongly suggest him for your courses and lessons
