I had the pleasure of being taught and guided by the beautiful Nat and Maya today on a 1 day try dive offered by Chalok Reef Divers. The whole process from basic theory, to the basics in a pool, to diving 12m and swimming through coral reefs was an absolute delight to say the least. They picked me up, took me to where I needed to be, and dropped me off. The entire time I felt so safe, seen and looked after. WHEN I come back to Thailand I will be coming to dive with these guys again🥰 Thank you for an incredible day I won’t forget.

I had an awesome scuba diving experience with Santi at Chalok Reef Divers! Every jump into the ocean was fun, safe, and full of laughter. Santi was a fantastic instructor—patient, knowledgeable, and somehow made me look almost like a pro instead of a confused sea turtle. Huge thanks to Chalok Reef Divers for an unforgettable adventure. Five stars, and I finally earned the title of sexy fish! (Open water Certified)

We had an absolutely amazing experience with Chalok Reef Divers! From the moment we arrived, we felt welcome and relaxed. The entire team created such a friendly, professional, and fun atmosphere that made every dive even more enjoyable. A very special thank you to our instructor, Nathalie. She was simply fantastic! She is incredibly patient, knowledgeable, encouraging, and always made us feel completely safe and confident in the water. Her positive energy and enthusiasm are contagious, and she made the whole experience unforgettable. This was truly the highlight of my trip thank you Nathalie!!

Exceptional Diving Experience – Beyond Koh Tao Standards! We had an incredible time with Chalok Divers and can’t recommend them enough! If you are looking for a professional and personal diving vibe, this is the place. The 3S-Trip: We booked the 3S-Trip to Southwest Pinnacle, Sail Rock, and Samran Pinnacle. Even though we couldn’t dive Samran due to the weather, the trip was fantastic and very well organized. • Note for others: This specific trip runs every Monday, Wednesday, and Saturday! The Team (Tim & Anna): A huge thanks to Tim and Anna. They were super professional, kind, and provided a level of service that clearly exceeds the usual standard on Koh Tao. We also really appreciated that they provide dive computers for everyone—a great safety standard! The Office (June): Special thanks to June! Her customer service is truly extraordinary—she is so warm-hearted, welcoming, and gave us excellent advice. She makes you feel at home the moment you enter the shop. •To the Boss: Whatever you are paying June, she definitely deserves a raise! ;) She is an absolute gem and a true asset to your team. We felt perfectly taken care of and will definitely be back. Thank you for making our time on Koh Tao so special!

⭐⭐⭐⭐⭐ We can’t recommend Chalok Reef Divers highly enough! We did our Advanced Open Water with Miguel, an absolute legend! We saw a huge improvement in our buoyancy, air consumption, and overall comfort underwater. After that, we did another 4 fun dives with Lucas, who was completely on point, a true professional who made the whole experience smooth, safe, and really enjoyable. Their gear is top-quality, modern, and clearly well-maintained. Ana was fantastic with quick communication and even shared great local restaurant recommendations. Over our time with them, we logged nearly 7 hours underwater across 8 different dive sites, including two shipwrecks and some stunning pinnacles, with a diverse range of marine life. If you’re diving in Koh Tao, don’t look anywhere else — Chalok Reef Divers is the one! 🤿🐟🐠🐡
