Did a Try Dive with my tour group, White Rock is world class! Loved it so much came back for my Advanced Open Water course 2 days later, had an absolute blast. Very professional and fun scuba school, and gorgeous dive sites on this Island! Lydia and Chris were so great, and Liv and Anna were very friendly too. Thanks for giving me my new obsession!
Had an amazing dive with the fellas at Goodtime. Ryan, Martin and Mira did a wonderful job, 1000+ recommended. Plus: a couple of days before the dive I rented some climbing gear from them, if ever in Ko Tao def try that, amazing routes and sights.
A huge thank you to Ana🩵, she's so sweet ☺️ The right person in the right place. I enjoyed my trial dives with her; she knew how to reassure me and show me how to enjoy diving without any worries or fears ✨ And she even has a super cute little fish toy attached to her wetsuit 🤩 Thank you, Ana 🩵 AL
If you want to get your diving license, come to Goodtime Adventures! The entire team Lisa, Gilly, Lukas, Mike, and especially Ana are incredibly professional and welcoming. They make you feel safe and confident during every dive, while also creating an unforgettable experience. A special thanks to Ana an amazing instructor who truly goes above and beyond! And if you want great photos from your dives, I highly recommend asking Mike. The pictures he took are absolutely fantastic. Cheers!
Fantastic experience as a first time diver! Ana made us feel so comfortable and we did such a brilliant dive near Nang Yuan. Would highly highly recommend!
What incredible experience! Anna was a fantastic scuba instructor. She had such a knowledgeable and calming presence, we felt so safe. I can’t recommend this company enough! (And mostly Anna)
