The sun leans low over the Gulf of Thailand as the vintage wooden boat slips from Mae Haad pier, the deck warm underfoot and salty wind rubbing at your face. Guests spread out on the sun deck while the captain eases toward Koh Nang Yuan — a string of three islets joined by a white sand spit that seems to hum with reef life. Throughout the day the sea teases and then gives: glassy shallows at Mango Bay, a scatter of reef fish in Hin Wong, and the Japanese Gardens where coral gardens crouch below a foot of water.

The sun leans low over the Gulf of Thailand as the vintage wooden boat slips from Mae Haad pier, the deck warm underfoot and salty wind rubbing at your face. Guests spread out on the sun deck while the captain eases toward Koh Nang Yuan — a string of three islets joined by a white sand spit that seems to hum with reef life. Throughout the day the sea teases and then gives: glassy shallows at Mango Bay, a scatter of reef fish in Hin Wong, and the Japanese Gardens where coral gardens crouch below a foot of water.
Koh Tao’s coastline is shaped by reef growth on a shallow platform, and Koh Nang Yuan’s sandbar is a recent geological ribbon created by currents and coral detritus. Culturally, the islands are small fishing and diving communities that grew around dive schools; signs of that trade—dive flags, compressor housings, equipment racks—dot the shore.
Expect a full 9‑hour outing with multiple snorkeling stops (guided at coral sites), equipment provided with a new mouthpiece, kayaking and paddleboarding options, a buffet lunch onboard and a BBQ dinner at sunset. Restrooms are on the boat and pick-up/drop-off is included.
Practical edge: wear reef-safe sunscreen, a snug mask and reef shoes for rocky swim entries. Bring a light wind layer for the return trip when the temperature drops with the setting sun. If you’re prone to motion sickness, take medication before boarding. The pace is relaxed but active—this is a long day on the water that rewards curiosity: float, point your mask down, and let the currents show you the reef.
It’s approximately a 9‑hour day trip that visits Koh Nang Yuan, Mango Bay, Hin Wong, Aow Leuk and other snorkeling points around Koh Tao, ending with sunset and BBQ aboard.
Yes—snorkelling equipment is provided and a new mouthpiece is supplied to each guest; you may bring your own mask if preferred.
Lunch (buffet) and a BBQ dinner are included, along with unlimited soft drinks, coffee and tea; bring cash for tips or extras ashore.
The trip is listed as suitable for all fitness levels, but infants must sit on an adult’s lap; non-swimmers should notify staff and can use flotation devices under supervision.
