Koh Chang: PADI Open Water Diver Course & Boat Dives

Summary

Learn to dive in Koh Chang with real reef boat dives

You’ll learn scuba basics in Koh Chang with real pool practice before heading out for four boat dives around local reefs. Expect hands-on help from your guide, lunch on board between dives, and small group support as you earn your PADI Open Water Diver certification — plus a few laughs along the way.

What’s the experience like?

I’ll admit, I was nervous the first morning — you know that feeling when you’re not sure if you’ll look ridiculous in all the gear? But our instructor, Somchai, just grinned and handed me a mask like it was no big deal. The theory part surprised me; it wasn’t dry at all. We sat by the pool under these droopy palm trees, flipping through the PADI manual and laughing about how I kept confusing “buoyancy” with “boyancy.” Somchai didn’t mind my questions (there were a lot), and somehow by lunchtime I felt like maybe I could actually do this.

The next two days are honestly a blur of saltwater and sunlight. Getting on the dive boat off Koh Chang felt like stepping into another world — everyone barefoot, chatting quietly over iced tea while we motored out toward Koh Rang. The sea had that glassy look you only get early in the day. My first open water dive… well, I almost forgot to breathe through my mouthpiece because there was this sudden hush underwater, just bubbles and distant parrotfish crunching coral. At one point Somchai pointed out a tiny nudibranch — I’d never even heard of those before — and then gave me a thumbs up when I managed to clear my mask without panicking. Lunch on the boat tasted better than it probably was because we were all starving and salty.

By the last dive, something shifted. I stopped thinking so much about what could go wrong and started noticing little things: how sunlight flickers on sand at 12 meters down, or how everyone’s hands move slower underwater like we’re all learning a new language together. It’s strange but after three days with this group — swapping stories over buffet lunch, rinsing off gear side by side — it felt like we’d known each other longer than that. There’s still sand in my bag from that last afternoon.
