Vielen lieben Dank für diese einzigartige und unglaubliche Erfahrung und Entdeckung einer neuen Welt. Ich hatte sehr viel Spass beim OWD und kann es weiterempfehlen bei Thai Ocean Tauch Kürse zu absolvieren. Das Team besteht aus wunderbar liebevollen und engagierte Persönlichkeiten. Ich hab sie alle sehr ins Herz geschlossen! Und freue mich sie alle bald wieder zu sehen. Thank you very much for this unique and incredible experience and discovery of a new world.

Trent is a super cool and relaxed guy, he makes everything clear and he's really easy to get along with. I learned so much in the few days I went diving with him, and his enthusiasm for his business is wonderful. There's also a dive shop dog which is the perfect welcome back from a long day on the boat! I will definitely come back here soon one day 🙂

Ich bin dankbar, bei euch meine erste Dive Experience gemacht zu haben. Ich habe großen Respekt vor Wasser und liebe es zu Gleich. Dank Rick an meiner Seite, haben sich meine ersten Tauchgänge sehr gut angefühlt. Er hat viel Ruhe ausgestrahlt und war immer an meiner Seite. Insgesamt wird hier ausgestrahlt, wie viel Liebe drin steckt und Spaß dabei ist! Auch waren wir insgesamt ein kleines Boot mit weniger Leuten, was sich so gut und vertraut anfühlt. Meine zwei Freunde, welche bereits erfahren sind, durften auch mitkommen und in meinem Schatten dabei sein. Es war ein unglaubliches Erlebnis und ich kann das nächste Mal kaum abwarten. <3

Had two insanely great days with the people from Thai Ocean Academy. Top modern equipment, great dive spots and totally relaxed people who made my vacation even better. I hope to come back to Koh Chang soon to dive here again.



After working in the industry for multiple years, learning about about the different diving styles, dive sites in the area and honing their skills not only in Thailand but worldwide, three men that initially met on Koh Chang decided it was time to start their own dive shop. Thai Ocean Academy Koh Chang was born in the midst of the pandemic, but the vision for its owners was clear: provide outstanding service as well as equipment and go above and beyond what’s required by the standards.

They spent time carefully selecting their team, stocking their equipment and buying a dive boat that was brought to Koh Chang on a sleepless 21 hour journey on the ocean (but that’s a story for another day 😉 )

With tourism picking up, the dive center is growing organically and making customers happy since 2022.
