Best place to learn to scuba dive. Anna and Char were amazing. Best experience would recommend to anyone for fun dive or getting their certs
Completed my open water training with a massive thanks to Lydia who I fully recommend for anyone planning on doing any diving in the future.
I had 6 lovely dives with Julia, Marc, Tim and Shai. The Store is good equipped and the dive masters/ guides are kind and well prepared. The quiz night was also great fun. Thank you for the whole experience!
Nice and chill dives with Shai.Everything was smooth and wonderful!!
We went diving for the first time in Ko Tao with this school. We had a fantastic time, and Lydia (the divemaster) was very kind, helping us set up our equipment and being very patient with us. Highly recommended.
Did a refresher dive with Carmen. Very nice bar and very good dive center
