Koh Samui: Ang Thong Yacht Day with Kayak, Blue Lagoon & Sunset

Summary

Kayak secret lagoons snorkel reefs and watch sunset from deck

You’ll kayak through caves to a hidden lagoon in Ang Thong Marine Park, snorkel vibrant reefs at Koh Wao with gear provided, and climb to the Blue Lagoon viewpoint after other tours have left. Relax on deck with Thai fusion lunch and sunset views before returning to Koh Samui — it’s a day full of small surprises and quiet beauty.

What’s the experience like?

First thing I noticed was how the light bounced off the water near Maenam Beach — almost too bright, but in a good way. We climbed aboard the Red Dragon (barefoot, which felt oddly freeing), and our guide Pim grinned as she handed out cold towels. There was this faint smell of lemongrass from somewhere below deck. The Five Islands drifted by, all jagged edges and birds wheeling overhead. Pim mentioned something about bird’s nests being harvested here — I’d never heard of that before, and honestly, I still can’t quite picture it.

We kayaked along Ang Thong’s cliffs after that, paddles clacking against the hull. The water was so clear you could see every flicker of fish below. At one point we ducked into a cave — echoey and cool — then out into this hidden lagoon where it got almost silent except for someone laughing behind me (I think they dropped their paddle). Afterward, some folks took the dinghy instead; no pressure either way. Lunch came while we cruised past these weird rock formations — spicy curry, sticky rice, fresh pineapple — all made right there on the boat. I tried to eat slowly but failed.

Snorkeling at Koh Wao was wild — schools of neon fish everywhere, and our crew kept an eye on everyone (even set up a floating raft for non-swimmers). My mask fogged up twice but nobody cared; we were all just floating around pointing at things under the surface. Later we stopped at Ko Mae Ko for the Blue Lagoon climb. The stairs were steeper than I expected (my legs are still mad), but when you reach the top… well, let’s just say it’s not something you forget quickly. There was barely anyone else there since we were the last boat allowed in.

On the way back to Koh Samui, people sprawled out on beanbags or dipped toes in the jacuzzi. Someone passed around banana splits as the sky went orange-pink over Phaluai Island — you could hear distant laughter from fishing boats as we floated by. I kept thinking about that silent lagoon earlier; funny how those moments stick with you more than any photo ever could.
