I've never left a review on TripAdvisor before, but I just have to for Scuba Shack because of the incredible experience I had with them! I just completed the PADI open water diving course with them over the 2021/2022 New Year holiday while I was in Koh Tao. Every single staff member is fun and easy to talk to, but more importantly I felt safe and comfortable with them. They were professional, yet super cool like I was hanging out with friends. They are all highly experienced divers, and know Koh Tao dives in and out. They all speak English, if that is something you need to consider. All the instructors are passionate about diving, and will make you too! The experience was everything I was hoping for and more! What else can I say? Super fair prices, great location on Koh Tao, the Scuba Shack is right on the beach AND there is fun little bar right in front, stocked with all the Thai beers you need after a long day of diving! I'm going back in a few months (: Have so much fun!!!
