⭐ 4.9/5 on Google · I chose Aquatao because I'd heard it was a small, family-run school — and that's exactly what I found 🥹 The welcome and the team are wonderful. I fell in love with diving, and they're a big part of why 👩🏻‍🎓 One discovery dive led to the Open Water, then the Advanced. A huge thank you to everyone 🙏🏼 See you soon in Koh Tao 🥹🫶🏼
