Koh Nang Yuan
Three islets joined by a sandbar you can walk across, minutes off Koh Tao. We land in the first hour, before the day boats make it somewhere else entirely.
Where
Koh Tao
Best time
The first boat of the morning. By ten it is a different island.
Koh Nang Yuan is three granite outcrops sitting a few hundred metres off Koh Tao's north-west shore, tied together by a sandbar that surfaces as the tide falls. You walk from one island to the next with water at ankle depth on both sides of you. It is one of the genuinely unusual coastal formations in Thailand, and it is very small — which is the entire problem and the entire solution.
The island is privately managed. There is a landing fee, one set of buildings, one restaurant, and rules — no single-use plastic bottles ashore, restrictions on fins over the shallow coral — enforced with more seriousness than most Thai beaches manage. It works. The hard coral on the eastern side, the site divers call the Japanese Gardens, is in better condition than anything comparable this close to a busy beach.
By ten in the morning the sandbar carries a queue for the photograph. At seven it carries nobody.
The sandbar, and what the tide does to it
The formation is a tombolo — sand deposited in the shelter between islands until it joins them — and here two arms meet at the middle islet, which is why the shape reads as a Y rather than a line.
It is not permanent in the way rock is. The arms broaden and narrow through the tidal cycle, submerging in places at high water and running wide and dry at low, and they shift over years with the weather. Which is why the walk is worth timing: on a falling tide you get the full span with water on either side of you, and on a high spring tide you may be wading rather than walking it.
The Japanese Gardens
The reef on the eastern side of the sandbar is a shallow field of hard coral — staghorn and boulder forms, mostly — in two to eight metres of clear water, close enough to shore that you simply swim out to it. Divers use it as a first open-water site because there is no current worth the name, and snorkellers get most of what divers do, because the depth is trivial.
It is also fragile: standing coral in water shallow enough to stand up in, which has survived only because the management restricts what people may do over it. Fins are limited and feet stay off the coral, and both rules are worth taking seriously.
The viewpoint, and the hour to climb it
A flight of steps and then a boulder scramble climbs the eastern islet to a platform that gives the image everyone has seen of this place: two arms of white sand curving between three green rocks, in graduated blues. It takes ten or fifteen minutes and it is not difficult, though the rock is hot by mid-morning and there is no shade on it.
The same platform at eight and at eleven is a different experience altogether — solitude in the first case, a slow-moving queue for a spot on the rock in the second. Go before anybody else does, and the rest of the island follows the same rule.
How We Visit
Our way in
Koh Nang Yuan is a ten-minute run by longtail from Koh Tao, so the only variable that matters is the hour. We put you on the water for the first landing of the day, which means the viewpoint and the sandbar with nobody on them and the Japanese Gardens flat and undisturbed. Breakfast happens afterwards, aboard or back on Koh Tao. Where the day continues we carry on to Shark Bay or out to the pinnacles rather than sit through the arrival of the fleet. The landing fee is settled on your behalf.
Questions
What travellers ask
Do you have to pay to visit Koh Nang Yuan?
Yes. The island is privately managed and charges a landing fee for day visitors, collected on arrival. The same management enforces the rules that have kept the reef in good condition: single-use plastic bottles are not permitted ashore, and there are restrictions on the use of fins over the shallow coral. We settle the fee as part of the day, so nothing needs handling at the jetty.
Can you walk across the Koh Nang Yuan sandbar?
Yes, at most states of the tide. The sandbar is a tombolo joining three islets, and on a falling or low tide it runs wide and dry with water on either side of you. On a high spring tide parts of it submerge and you wade instead. It is a few hundred metres from end to end, and the walk across it is the reason most people come.
What time should you go to Koh Nang Yuan?
First thing — before eight if you can manage it. The island is very small, and the day boats from Koh Tao and Koh Samui begin arriving mid-morning, after which the sandbar and the viewpoint both carry a queue. On the first boat of the day you get the climb, the sandbar and the snorkelling on the eastern reef with almost nobody else there. By ten it is a different island.
