Koh Tao was a prison island. Between 1933 and 1947 the Thai government held political detainees on its twenty-one square kilometres of granite and jungle, and no civilian was permitted to land. An amnesty emptied the cells in 1947. Families from neighbouring Koh Pha Ngan arrived soon after, planting coconut across slopes that now hold dive schools. The name translates as Turtle Island, for the hawksbill and green turtles that once nested along its bays. That long emptiness explains the reefs a Koh Tao snorkeling tour from Koh Samui now visits: they were left alone for decades. One kilometre off Koh Tao's northwest coast, Koh Nang Yuan is not one island but three granite outcrops tethered by a triple sandbar that shifts with the tide. The formation is the anchor point of nearly every Koh Tao snorkeling tour from Koh Samui tour itinerary. It is privately managed. A 250 THB conservation fee applies per person, plastic bottles are refused at the jetty, and the islets receive visitors from 10:00 to 15:00. The address is simply Koh Nang Yuan, Koh Tao, Surat Thani. The rock is weathered granite, stacked in rounded boulders above the water. Koh Tao certifies among the highest numbers of open-water divers of any island on earth, a record built on sheltered bays and steady visibility in the Gulf of Thailand. The same conditions serve snorkellers. Japanese Gardens, on Nang Yuan's eastern flank, carries staghorn and table coral in three to six metres of water. Shark Bay, on Koh Tao's south coast, shelters juvenile blacktip reef sharks over seagrass. Chumphon Pinnacle, a submerged granite tower northwest of the island, draws whale sharks in the months either side of the monsoon. Snorkelling day trips to Koh Tao and Nangyuan Island follow the same protected water the dive schools use. Bleaching events have closed individual reefs in recent years, and Thai marine authorities rotate access to let them recover. The conservation fee funds that work rather than decorating a receipt. Koh Samui lies roughly sixty kilometres south, which is why speedboat day trips from Samui long ago replaced the longtail. Koh Tao snorkeling tour from Koh Samui tours have run daily since the piers at Bangrak and Mae Haad were rebuilt for passenger traffic. What was a fishing route between two granite islands is now the busiest snorkelling corridor in the lower Gulf, and the sandbar at its centre has not moved.
"The reefs were left alone for decades, and the sandbar at their centre has not moved."
A step-by-step walkthrough of the visit — what you'll see, how long each stage takes, and the details that matter.
You board at a Samui pier while the sea is still glass, and the hull slaps flat water for the first stretch north. Spray arrives on the second stretch. Somewhere past the halfway mark the granite of Koh Tao lifts out of the haze, low and green, and the engines drop. Your Koh Tao snorkeling tour from Koh Samui tickets cover the crossing; the 250 THB conservation fee is collected separately at the Nang Yuan jetty, per person, in cash. You step onto a wooden walkway and the sandbar appears — a curved spit of white sand joining three islets, shallow enough to wade. Fins are not permitted here. You leave them on the boat. In the water off the eastern shore you find staghorn coral at three to six metres, parrotfish grazing audibly on the hard heads, and a triggerfish that makes you back away. You surface, clear your mask, and swim the channel between two of the islets, where the current tugs gently sideways. Later you climb the boardwalk stairs toward the granite outcrop above the beach. The stone is hot underfoot. You pause partway, turn, and see the sandbar from above: two arcs of turquoise pressed against one white line. Then you go back down and swim again.
The conservation fee is 250 THB per person, payable upon arrival at Koh Nang Yuan.
