I thought I’d seen the most beautiful islands Thailand had to offer — and then I visited Koh Nang Yuan. A trio of tiny islands connected by one impossibly white sandbar, with water so clear it barely looks real. Not surprisingly, Koh Nang Yuan is one of the most unique and photogenic places to visit in Thailand!
You should know that Koh Nang Yuan is actually not just one island but three islands connected by a sandbar so narrow you can stand with a foot on either side and look out at two completely different bays.
You’ll see turquoise water, swaying palms and huge boulders tumbling into the sea, and the island is small enough to explore in a single day. It’s one of the most photographed spots in the entire country, and honestly my photos don’t do it justice because I visited during the rainy season on a cloudy day.
In this Koh Nang Yuan guide I’ll cover everything you need to know before you visit so you don’t make the same mistakes as I did. I’ll let you know how to get there, what to do on the island, where to eat, how to stay overnight, and all the practical tips to make the most of your trip.

Getting To Koh Nang Yuan
Koh Nang Yuan is a small island only accessible by boat, but there are good options whether you’re already on Koh Tao or coming from further afield. Here’s how to get there from the most common starting points.
From Koh Tao: Long tail Boat from Sairee Beach
The easiest and cheapest option. Long tail boat captains are stationed on Sairee Beach and the standard rate is around 250 THB per person return, though drivers may open at 300 THB so be ready to negotiate. The crossing takes about 10–15 minutes. Agree on a pick-up time before you go, and your driver will come back to collect you at the pier.
From Koh Tao: Kayak or Boat from Dusit Buncha Resort
Another option for getting to Koh Nang Yuan from Koh Tao is via the Dusit Buncha Resort which sits on Koh Tao’s northwest tip, making it the closest point on the island to Koh Nang Yuan. If you’re staying there, the resort runs boat transfers across (a handy perk that saves you heading to Sairee Beach.) Non guests can also take advantage of the boat transfers for a small fee.
It’s also possible to kayak from the resort when the sea is calm. The crossing is around 15 minutes and it’s a fun and adventurous way to arrive, just make sure you’re a confident open-water paddler and keep an eye on conditions before you set off.
From Koh Tao: Snorkelling Day Tours
If you want to make a full day of it, a snorkelling tour is a brilliant option and arguably the best way to visit Koh Nang Yuan. Several operators on Koh Tao run day trips that combine a stop at Koh Nang Yuan with snorkelling at Koh Tao’s hidden bays, including spots like Hin Wong Bay, Aow Leuk Beach, and Shark Bay.
On this top rated tour you’ll visit four or five snorkelling sites across the day, with the chance to see reef sharks, sea turtles, and vibrant coral gardens. The tour includes snorkelling equipment, lunch on board, and hotel pick-up but do note that the 250 THB entry fee is usually paid separately in cash at the entrance to the island. Prices start at around 900 – 1200 THB per person for a full day.
From Koh Phangan
Koh Phangan is around an hour from Koh Nang Yuan by speedboat, making it a very doable day trip. The best option is to book an organised snorkelling tour, which will take you to both Koh Tao and Koh Nang Yuan in one day.
This speedboat tour from Koh Phangan departs from Thong Sala Pier and include a light breakfast, lunch, snorkelling gear, and hotel transfers. Prices tend to run around 2,000–2,500 THB per person all-in.
Alternatively, if you’re travelling to Koh Tao anyway, the Lomprayah high-speed catamaran from Thong Sala Pier takes around 90 minutes to Koh Tao, from where you can take a longtail straight to Koh Nang Yuan. Book your ferry on 12 Go Asia.
From Koh Samui
It’s further from Koh Samui (around two to two and a half hours by speedboat or high-speed catamaran to Koh Tao) but it’s still very much doable. The most popular approach is to book a day trip tour that combines Koh Tao snorkelling with a stop at Koh Nang Yuan, with most departing from Bangrak or Nathon Pier and costing 2,000–2,500 THB per person.
This speedboat tour from Koh Samui includes breakfast at the pier and buffet lunch on the island, snorkelling gear and hotel pick up. Bear in mind that you’ll have less time on the island than if you were based on Koh Tao, so a tour rather than an independent trip makes more sense from here.
Staying Overnight
The only way to stay on Koh Nang Yuan itself is to book a room at Koh Nang Yuan Dive Resort. Staying overnight means you get the island almost entirely to yourself in the early morning and evening which is a magical experience.
Things To Do On Koh Nang Yuan
Koh Nang Yuan Viewpoint Hike
If you do nothing else on Koh Nang Yuan, you must do the short hike to Koh Nang Yuan viewpoint. It’s the image you’ve seen all over Instagram — that bird’s eye shot of the three islets and the sandbar connecting them, with crystal-clear water on both sides.
The hike itself is short but steep, around 10–15 minutes up the steps. There’s a bit of rocky path but there’s a rope to help you on the steeper sections. It’s totally manageable in flip flops and it’s not a strenuous hike, but it’s not entirely leisurely either. As the viewpoint is very small you might have to wait on the steps for 10 minutes for your turn on the famous rock with a view.
Once you reach the top, you’re rewarded with one of the most spectacular viewpoints in Thailand. The sandbar stretching between the islands below you, water in all different shades of blue, and on a clear day, you can see out to Koh Tao and beyond.
Timing tip: Get up there early, at 10am if you can, or wait until late afternoon. Midday sees the most day-trippers, and you’ll be waiting in a queue at the top for your unobstructed shot. The golden hour light in the late afternoon is worth the wait if your staying on the island.
Koh Nang Yuan Beach and the Sandbar
The sandbar is the star of the show. It’s a strip of powdery white sand that connects the three islets and creates two completely different bays, one on either side. At low tide it’s wide enough to walk comfortably and feels almost impossibly beautiful; at high tide it narrows significantly, so if you want the full sandbar experience it’s worth checking the tide times before you go.
The two bays have slightly different personalities. The western side is calmer in the morning and catches the best of the late afternoon light (it’s the one that faces the sunset if you’re staying overnight.) The eastern bay is more sheltered and tends to be popular with snorkellers, with good reef access straight from the shore. Neither beach is particularly large, and by midday in peak season the sandbar can feel busy, so arriving early before the tour boats really does make a difference.
The water is extraordinary; shallow, warm, and so clear you can see the bottom several metres down without even getting in. It’s the kind of turquoise that looks filtered even in real life. Bring an underwater camera if you have one, because the snorkelling straight off the sandbar is genuinely excellent. It’s one of those happy surprises that makes the island even better than the photos suggest.
The sandbar is very exposed to the sun with limited natural shade out on the sand itself. Beach chairs and umbrellas are available from the resort. They provide free beach chairs and umbrellas for overnight guests while day visitors will have to pay 200 baht per day to rent.
If you’re not renting a beach chair, stake out a spot near the palm trees at the edges. Either way, sunscreen is non-negotiable as the Thai sun is intense but make sure it’s reef safe sunscreen.
Snorkelling and Diving
Snorkelling
The waters around Koh Nang Yuan are some of the clearest around Koh Tao, and snorkelling here is usually excellent. The sandbar area itself is shallow and calm which is great for beginners, while the rocky outcrops around the edges of the islands and coral reefs hide a surprising amount of marine life.
Look out for coral formations, parrotfish, butterflyfish, and if you’re lucky, the occasional blacktip reef shark nosing along the bottom. Hawksbill sea turtles have also been spotted in the waters here.
Snorkel gear can be hired from the resort or brought from Koh Tao. If you’re doing a day trip, many boat operators include snorkel gear in the price.
Scuba Diving
Koh Nang Yuan is home to some of Koh Tao’s most popular dive sites. The island is run by a dive resort for a reason — the diving here is world-class, particularly for the Gulf of Thailand. Here’s some of the best dive sites you can access from Koh Nang Yuan:
Chumphon Pinnacle
One of Thailand’s top dive sites, Chumphon Pinnacle is a series of underwater granite peaks around 13km northwest of Koh Nang Yuan. It’s a magnet for whale sharks, barracuda, and massive schools of fish. Visibility here can exceed 20 metres on a good day.
Southwest Pinnacle
Another excellent site, Southwest Pinnacle is known for its coral-encrusted boulders and strong currents that attract large pelagics. Good for intermediate divers and above.
Japanese Gardens
A shallower, more sheltered site perfect for beginners and snorkellers. The coral gardens here are colourful and well-preserved, with plenty of reef fish to spot.
Koh Nang Yuan Dive Resort offers fun discover dives to PADI courses from Open Water through to advanced levels, as well as fun dives for certified divers. Book directly through the resort or through dive operators on Koh Tao.
Where to Eat & Drink on Koh Nang Yuan
Because Koh Nang Yuan is a private island, all food and drinks are served exclusively by the resort and bringing your own food or drinks onto the island is not permitted. There’s no getting around it, so factor the resort pricing into your budget before you go.
The resort has a beachside restaurant and bar serving Thai and Western dishes, fresh fruit, smoothies, and cocktails. The quality is decent but the setting is gorgeous, and eating lunch on the sandbar with that view is genuinely hard to beat.
If budget is a concern, eat a proper meal on Koh Tao before you head over so that you’ll only need drinks and maybe a snack on the island itself.
Top Tip: Expect to pay noticeably more than you would at a restaurant on Koh Tao — it’s a resort monopoly, so plan accordingly.
Where to Stay: Koh Nang Yuan Dive Resort
If you want the island experience beyond a day trip, and honestly I’d argue it’s the best way to visit Koh Nang Yuan, Koh Nang Yuan Dive Resort is your only option, which also makes it an easy choice.
The rooms range from simple hillside bungalows to beachfront options with sea views. They are comfortable rather than luxurious, and priced accordingly for a private island monopoly. Be honest with yourself going in – you’re paying for the location, not a five-star experience.
Reviews are mixed on the accommodation itself, but overwhelmingly positive on the overall experience of staying here. Waking up to the sound of the sea and having the entire island almost all to yourself (apart from a few other people also staying at the resort) before the day-trippers arrive at 10am is, by all accounts, genuinely magical.
Room rates include breakfast and return boat transfers from Koh Tao. You can book via Booking.com, where you can read recent guest reviews or book direct through nangyuan.com if you prefer. Book well in advance during peak season (December–March) as the resort has limited rooms.
Best Time to Visit Koh Nang Yuan
Another thing worth knowing when you plan to visit Koh Tao and Koh Nang Yuan is that they sit in the Gulf of Thailand, which has a completely different weather pattern to Phuket and the Andaman Sea side of the country.
December to April: Peak Season
This is the best time to visit. The skies are reliably clear, the seas are calm, and underwater visibility is at its best which matters a lot if you’re here for the snorkelling or diving. December through February is especially popular, so expect more crowds on the island and higher prices for accommodation. If you can visit in March or April you’ll get similar conditions with slightly fewer people.
May to July: Shoulder Season
An underrated time to visit. Conditions are still generally good (warm, mostly sunny, and the seas are manageable) but the crowds thin out noticeably and prices drop. If avoiding the peak season rush is a priority, May to July is a good window. The odd shower here and there, but nothing that will ruin a day trip.
August to October: Quieter but Wetter
Rain becomes more frequent and seas can be rougher, but this doesn’t mean the island is off limits. Bad weather here rarely lasts all day, and you’ll often get stretches of beautiful sunshine in between. The big upside is that it’s genuinely quiet and great value. If you’re flexible with your plans and happy to go with the flow, you might find you practically have Koh Nang Yuan to yourself.
November: Avoid if Possible
November is the Gulf of Thailand’s stormiest month and the one to be most cautious about. Seas can be rough, boat services to Koh Nang Yuan may be cancelled at short notice, and the island can lose its magic fast when the weather turns. It’s not impossible to visit, some people get lucky, but if you have flexibility, this is the month to plan around rather than plan for.
The honest answer is that Koh Nang Yuan is worth visiting whenever you can get there, apart from November. Just check the conditions before you jump on a boat, have a backup plan for rough days, and don’t let the idea of an imperfect season put you off.
Things to Know Before You Go
- Bring cash. The island is remote and card facilities may not always work reliably. ATMs are on Koh Tao so sort your cash before you get on the boat.
- Wear shoes for the viewpoint hike. Flip flops are technically fine but the path is steep enough and rocky in places that proper footwear makes a difference.
- The entry fee is non-negotiable and worth it. 250 THB (around £5.50 / $7) for access to one of Thailand’s most beautiful spots is reasonable. Don’t arrive expecting to negotiate.
- Bring your own snorkel gear from Koh Tao if you have it, to save on rental costs at the island.
- Go early or late. Midday is peak day-tripper time. The island is genuinely more magical in the morning light or late afternoon when the crowds thin out.
- No plastic means no plastic. Don’t try to sneak in a water bottle. They’re serious about this and it’s one of the reasons the island stays so pristine.
- Book overnight stays well in advance during peak season (December–March). The resort has limited rooms and is popular with divers.
- Check the weather before you go. On rough days, boats to Koh Nang Yuan may not run, or the crossing may be choppy. Have a backup plan.
Is Koh Nang Yuan Worth Visiting?
Short answer: yes, unequivocally.
Even if island-hopping isn’t normally your thing, Koh Nang Yuan is different. It’s the kind of place that feels genuinely special rather than just another beach. The combination of the sandbar, the viewpoint, and the clarity of the water is hard to find anywhere else in Thailand.
The crowds can be real in peak season, and the fact that everything on the island is resort-priced is worth knowing. But neither of those things should put you off. Get there early, hike the viewpoint, snorkel the sandbar, and sip a cold drink with your feet in the sand. It’s about as close to paradise as you’ll get in the Gulf of Thailand.
If you’re already on Koh Tao, skipping Koh Nang Yuan would be a mistake. It’s the kind of trip that ends up being the highlight of your whole Thailand trip and if you can stay overnight the experience is magical.
