We're a family of seasoned divers, and this is our first time in Thailand.
My expectations were contained, because I thought this beautiful country is not exactly world class in terms of diving. I was WRONG!
Alice, the lovely lady who runs the shop, has this uncanny gift to turn almost every dive into something unique. Seahorse for example: I see one every 300 dives, and this is my second. Assuming 50 USD for one dive, that's a 15000 USD value! She also set up a drag race between me and a black tip reef shark; I crossed the finishing line in P2, not bad for a human 🙂.
All in all, these guys have my warmest recommendation. Heil Switzerland!
