You board a boat with fewer than sixteen others, spend 90 minutes reaching Nang Yuan, climb to its viewpoint, snorkel the shallows, then motor to Koh Tao for lunch and a second snorkel in deeper water. Hotel pickup, gear, and meals are included. The whole day runs eight hours, and the small-group cap is what keeps it from feeling like a ferry ride with snorkels.
The boat leaves Bophut pier at a fixed time each morning, and you're on it with maybe a dozen other people instead of fifty. That's the whole difference. Koh Nang Yuan sits 90 minutes across the water from Koh Samui, and when you arrive the beach is still quiet — white sand that actually feels like yours for a moment, clear enough to see the seabed without trying. You climb the viewpoint path (it takes ten minutes, nothing steep) and the three small islands connected by sandbars spread out below you like a postcard someone actually took, not one someone Photoshopped. The snorkeling happens in the shallows around the rocks, and the coral and small reef fish are there because the group size stays small enough that the guides can actually point things out instead of just herding bodies.
After Nang Yuan you motor across to Koh Tao, where lunch waits — Thai-style, served on the island, nothing fancy but real. The afternoon snorkel is the longer one, the deeper one, where the underwater life gets more interesting. Your guide knows the spots that work, knows which direction the current runs, and because there are only sixteen of you total, he's not splitting attention between three different groups. The water temperature stays warm enough that you don't think about it. You see parrotfish, small groupers, the usual reef residents, and the visibility is what it is that day — sometimes brilliant, sometimes just good. Either way it's the Gulf of Thailand, not a swimming pool.
The boat back to Bophut takes the same 90 minutes, and you're dropped at your hotel by late afternoon. Hotel pickup happens in the morning from wherever you're staying on Koh Samui, and the driver knows the route. Lunch, snorkeling gear, bottled water and seasonal fruit are all included, so you're not hunting for a restaurant or renting a mask separately. The minimum group size is eight people, which is why the tour doesn't run every day — it runs when there are enough bookings — so check availability before you plan around it.
Your day includes hotel pickup and drop-off from your Koh Samui accommodation, snorkeling mask and equipment, a Thai-style lunch on Koh Tao, bottled water and seasonal fruit throughout the day, and travel insurance. The boat carries a maximum of 16 passengers, keeping the group small enough that the guide can actually point out what you're seeing underwater.

Is this one for you?Book this if you want to snorkel two islands in one day without arranging your own boat, timing, or meals — and you prefer a group small enough that you're not competing for the guide's attention or space on the sand.
