TL;DR: Koh Nang Yuan is three small islets joined by a single white sandbar, reached by a 10-30 minute taxi boat from Koh Tao’s Sairee Beach or Mae Haad pier for roughly ฿100-300 (about US$3-9) depending on departure point and how hard you negotiate. Day visitors pay a separate entrance fee on top: the island’s own resort site and current tour-operator listings put the 2026 rate at ฿250 (about US$8) per adult and ฿100-120 (about US$3-4) per child, though a few older travel blogs still quote a ฿100 rate, so budget for the higher figure to be safe. The island is open to day-trippers roughly 9:30-10am to 5pm, and the 10-20 minute climb to the famous viewpoint over the sandbar is an easy paved-and-boulder scramble rather than a technical hike. Snorkelling is decent on the west side of the island opposite the pier, with clear water and the occasional small blacktip shark. Arrive on one of the first taxi boats after opening, before the mid-morning wave of organised day tours from Koh Tao lands, if the empty-sandbar photo matters to you. All prices ฿33 = US$1 (July 2026).
If you’ve seen one photo of the Gulf of Thailand, there’s a decent chance it was this one: a thin white sandbar stitching two green islets together, shot from directly above. That’s Koh Nang Yuan, a private island a short boat ride off Koh Tao’s Sairee Beach, and the viewpoint climb that produces that photo is the main reason people go. This guide covers the entrance fee (which is genuinely inconsistent across sources, more on that below), how to get there, the hike itself, the snorkelling, the island’s strict no-plastic policy, and when to go if you want the sandbar without forty other people in the frame. Every figure below is checked against current 2026 visitor guides and the island resort’s own site, cited in the Sources section.
What is Koh Nang Yuan, and where is it?
Koh Nang Yuan is a cluster of three small islets connected by one continuous white sandbar, sitting just off Koh Tao’s northwest coast, close enough to see from Sairee Beach on a clear day. The island is privately managed, with a single dive resort, one restaurant, and a day-visitor system that charges an entrance fee separate from whatever you pay for the boat ride over. It’s usually visited as a half-day trip from Koh Tao rather than an overnight stay, either independently by taxi boat or as one stop on a wider snorkelling tour. For a broader look at what else is worth doing on Koh Tao itself, see outthailand.com’s things to do in Koh Tao guide.
Getting to Koh Nang Yuan from Koh Tao
A taxi boat from Sairee Beach is the fastest and usually cheapest way over, taking about 10-20 minutes. Longtail and small speedboat taxis wait at several stands along Sairee Beach, and you don’t need to book ahead, you just walk up, agree a price, and go. Boats also run from Mae Haad pier, a slightly longer crossing.
| Departure point | Crossing time | Typical price |
|---|---|---|
| Sairee Beach (one-way) | ~10-20 min | ฿100-150 (~US$3-5) per person |
| Sairee Beach (return, same boat waits) | ~10-20 min each way | ฿200-300 (~US$6-9) per person |
| Mae Haad pier | ~20-30 min | ฿100-500 (~US$3-15), varies by operator |
| Organised snorkelling day tour from Koh Tao | Included as one of several stops | From |
Prices compiled from multiple 2026 Koh Nang Yuan visitor guides; see Sources. Fares are commonly negotiable, especially for a return trip where you agree a pickup time with the same driver.
If you’d rather not negotiate a boat fare, book a taxi boat through your Koh Tao hotel or a tourist office, though expect to pay somewhat more than dealing directly with boatmen on the beach. Resort guests staying on Koh Nang Yuan itself get a free transfer included.
How much is the entrance fee, really?
Budget ฿250 (about US$8) per adult and ฿100-120 (about US$3-4) per child, paid in cash at the pier, though you may see a lower ฿100 figure quoted on older sites. This is one area where sources genuinely disagree: the island resort’s own website and current 2026 tour-operator listings both state ฿250 per adult, while several travel blogs, some clearly written a year or more ago, still list ฿100. The safest approach is to plan for the higher figure and treat anything cheaper as a pleasant surprise. Either way, the fee is separate from your boat fare and is collected on arrival, not bundled into any taxi boat price. Resort guests have it waived.
The viewpoint climb: what to expect
The hike to the viewpoint takes about 10-20 minutes on a paved, stepped path that turns into a short boulder scramble near the top. It’s not a technical climb, most visitors manage it in flip-flops or sandals, but the combination of stairs and Thai humidity means it’s completely normal to stop partway up to catch your breath. Near the summit the path narrows and you’ll squeeze between a few large boulders before reaching the lookout point, which delivers the panoramic shot of the sandbar and the three islets that makes this place famous. During the busiest hours, expect to queue at the narrowest points, some visitors report 20-minute waits when a large tour group is on the path at the same time.
Is the snorkelling any good?
Snorkelling is decent, best on the west side of the island opposite the main pier, and the shallow water around the sandbar itself is calm enough for casual swimmers. Visibility is generally clear, reef fish are plentiful, and some visitors report spotting small blacktip sharks in the area. It’s not the standout snorkelling site in the wider Koh Tao area, better spots exist elsewhere, but as a stop on a half-day trip it’s a solid add-on to the viewpoint climb rather than the main event. For dive sites and snorkelling further afield, see outthailand.com’s Koh Tao diving guide.
The no-plastic rule
Koh Nang Yuan enforces a strict single-use plastic ban, and staff check bags at the pier before you’re allowed to land. Plastic water bottles are the main target, some visitor accounts say even personal reusable plastic bottles get flagged, and plastic bags are also banned. Drinks bought on the island come in glass bottles instead, which does mean you’re paying island prices for water once you’re there. If you want to avoid the hassle entirely, bring a metal or glass bottle rather than a plastic one, or simply plan to buy your water on arrival.
Best time to visit to avoid the crowds
Go on one of the first boats after opening, roughly 9:30-10am, or wait until after 2:30-3pm when day-tour groups start heading back to Koh Tao. Multiple 2026 visitor accounts point to the same pattern: organised tour boats from Koh Tao converge on the island between about 10:30am and 3pm, which is when the viewpoint path queues and the sandbar fills with photographers waiting their turn. Outside that window, particularly right at opening, the sandbar and viewpoint are noticeably quieter. Sea conditions are calmer and visibility better in the dry season (roughly December to April), which is also when the island gets busiest overall, so there’s a genuine trade-off between best conditions and fewest people.

Honest downsides
Koh Nang Yuan earns its reputation, but go in with realistic expectations.
- It’s small, and there’s not much to do beyond the viewpoint, the sandbar and a swim. One restaurant, limited shade, and a fee on top of your boat fare mean it works best as a half-day trip, not a full day out.
- The entrance fee itself is a genuine grey area. Between the ฿100 and ฿250 figures floating around online, budget for the higher number so you’re not caught short in cash.
- Midday crowds are real. Between roughly 10:30am and 3pm, tour boats from Koh Tao converge here, and the viewpoint path can queue.
- The no-plastic rule, while good for the environment, catches people out. Turning up with a case of bottled water is asking for it to be confiscated at the pier.
- Closing time is firm. The last taxi boat back to Koh Tao leaves at 5pm; miss it and you’re relying on the resort, which isn’t cheap for a walk-in.
Putting it together
Koh Nang Yuan delivers on the postcard: the sandbar, the viewpoint, and a decent snorkel, all within a couple of hours of Koh Tao. Take an early taxi boat from Sairee Beach if you want the quiet version, budget ฿250 for the entrance fee to be safe, and leave the plastic water bottles behind. Pair the trip with a wider look at things to do in Koh Tao, check where to stay in Koh Tao if you’re still picking a base, and browse what’s on right now to see if anything on the main island is worth building the rest of your day around.
