Scubadoo is the perfect dive school with our brilliant instructor Simon.

Please please go with scubadoo if you have the chance! My girlfriend and I started on a try dive and inevitably ended up doing our open water courses and again I kept going by doing my advanced here. This was all down to my incredible instructor Simon, the safety, the epic dive sites and the great vibes from the team! Simon was a brilliant instructor, my girlfriend had a lot of nerves going in and now loves scuba diving, he is very informative and knows everything there is to know about scuba diving. I feel like I’ve learnt so much and feel so lucky to have been taught by him. On top of this, halfway through our stay in Koh Tao I had a problem with my hotel and moved to staying in scubadoo accommodation (rooms of 4) and honestly they were so perfect. Clean, comfy, spacious and private. As well as being surrounded by other scuba divers! Scubadoo is a brilliant dive school!

Super Scubadoo!! 🤿

The sign of a great trip has to be when travellers extend their stay! When we initially booked with Scubadoo we had checked in for 4 days, we ended up staying a month!!! Let me start with the hostel. Clean, Ai the hostel cleaner keeps the place immaculate. The mattresses are a touch hard, but the rooms are spacious, you'll hopefully meet some great roommates and the bathrooms are decent. The social area (TV, couch etc are inviting, especially as I can be a TV addict! Unwinding with some Netflix is certainly a chilled option at times). An online working area was also useful, catching up with emails or getting on the socials! Plus access to a fridge was also useful. The Scubadoo Diving Experience! I have dived once with my dad 25+ years ago in a lovely swimming pool in South London! On the flip of a coin I decided to take the plunge (!) and start with a fun dive, which not surprisingly lead to the Open Water Qualification. I now have 8 dives under my weight belt! I will always be eternally grateful to Mark for training me brilliantly, safe, methodical but most importantly with FUN and humour! Plus Luk who lead me on my most epic dive to date! A huge thank you to the Scubadoo team! Liam coordinates everything effortlessly! The dive team Simon, Mark and Uie (sorry about spelling!) are super cool! Luk is super chill and nothing is a problem! Stana is the hostess with the mostess! And Les helps keep things chill in the hostel. Thank you for a fabulous experience, we will return! 🙏🏻😊❤️🇹🇭🤿🏝️

Very professional!

Everything was 10/10! Service minded crew, good information and GREAT views. It was amazing. My instructor the 2 first days was Maria and she's great!! Very distinct and good instructions, and very kind! My instructor the last day was Alberto and he was also great!!! I couldn't have had better instructor's and I recommend you all to go to Scubadoo! 10/10 🪸👌🏼😄

Best diving center in Koh Tao

We had the most amazing time with Simon, learned everything we need to feel safe and have fun under the water. We passed the course with my boyfriend, I loved the fact that it was only the two of us with our teacher - unlike the big groups you could end up in if you pick other diving centres on the island. I’m actually sad our 6 dives are already over, it was a wonderful experience.

The best course and teachers ever! 🐟🌊

Neo and Harry were the best teachers! Felt so safe the entire time despite personal worries with some of the drills. Both were so patient and helpful throughout the entire experience making sure we were always comfortable and giving us tips to help ease our stress. They took us to the best spots and gave us great briefs on the location, what to expect and what we could see. Cannot recommend this experience and both Neo and Harry enough! The best few days and will definitely be back for more :) 🐟🌊

Outlandishly wicked open water diver course

I landed on Koh Tao with thick grey clouds overhead and was debating an island snorkeling tour, when, inspired by one of my clients who said they loved diving here, I decided to ask around a couple of diving shops. Scubadoo was the third and best priced and had a shop full of welcoming people. I signed up after a bit of research and had a blast completing my open water diver qualification. I’ve learned loads in what feels like even less time than the 2.5 day course and have made at least one mate from it! I’d highly recommend Scubadoo - big shout to Lukey, Harry and Jorge.

Best dive company

Best dive company, friendly and fun. Had the best time diving with Neo and the rest of the group. They made sure everything went smoothy and overall I had a great time :)
