The best islands in Southeast Asia
No photoshopping required
Too many islands, too little time! Thailand has more than its fair share of islands, and for the first time visitor, picking the right Thai island can be a pretty daunting undertaking.
So, here's an overview of some of the best islands in Thailand, including the best-known spots like Ko Samui, Ko Phi Phi, Ko Pha Ngan, Ko Tao and Ko Samet. We've also covered a smattering of the lesser known islands that you probably won't read about in your guidebook -- in our opinion these can be some of the best islands in Thailand.
Follow the individual links through for detailed guesthouse and hotel reviews, restaurant and bar listings, attractions and activities, a bunch of photos and maps and of course information on where the best beaches are.
Coverage of more of Thailand's many islands is on the way -- in the meantime, you may also want to read our story: What is the best island in Thailand?
Islands in Thailand
-
Coral & Raya Islands
Off Phuket's southern coast are a number of small islands whose pristine shores lure scuba-divers and beach bums away from the mainland. Most of these isolated islands are undeveloped, but the notable exceptions are Coral Island and Raya Island (also known as Racha Island) which have accommodation options and restaurants. Both islands have safe swimming, reefs teeming with aquatic life, and a sense of 'getting away from it all' that's harder and harder to come by in Phuket proper ... Coral & Raya Islands -
Ko Adang
Thailand's remote Ko Adang is an ideal island for nature-loving travellers who seek a less-populated haven well away from peak-season beaches packed with sunbathing limbs. With plenty of hiking trails, deserted white sand beaches and jungle waterfalls there's enough here for day-trippers from nearby Ko Lipe along with those who plan to spend a longer stretch of time exploring all this island has to offer ... Ko Adang travel guide -
Ko Bulon Lae
While under the radar for many, little-known Ko Bulon Lae remains popular with returning vacationers (particularly families) year after year. Bungalow resorts are scattered around the island, so choices are as varied as the travellers who stay here: windy hillsides, beaches with or without rocks and mangroves, forested or exposed to sun and salty air. Every night, the generators switch on and Bulon lights up for another laid-back evening. Many travellers come back again and again, to find the particular tranquility they've only found on Bulon ... Ko Bulon Lae travel guide -
Ko Chang
Most of Ko Chang's beaches are on the western coast, and each has built up with a distinctive atmosphere based on shopping, activities, partying or chilling out. Accommodation offers a style to suit every type of traveller, from independent low budget backpackers to those wanting a touch of luxury. There are plenty of activities to be organised from almost anywhere on the island: snorkelling and diving trips to nearby coral reefs, jungle treks and elephant rides, not to mention various beach sports. One of Thailand's fastest developing islands, don't miss the boat to this great destination ... Ko Chang travel guide -
Ko Kham
An idealic little blink-and-you'll-miss-it island barely a kilometre from Ko Maak, Ko Kham is a perfect spot to really get away from it all. Crystal-clear waters and a number of coral reefs make the island popular with the snorkelling crowd and many boat outings from Ko Chang stop here for an hour or two to have a look into the not-so-deep, but why not stay for a night or five? ... Ko Kham travel guide -
Ko Kho Khao
A rriving at Ko Kho Khao tends to leave visitors feeling like they've stumbled onto a wonderful secret -- but with a cluster of resorts already operating on the island and plenty more in the making, it's a secret that won't last long. There's no hotel or taxi touts waiting to greet you when you get off the boat, the roads are quiet and the locals very laid-back. There's an excellent beach along the coast looking out to sea and there's a fine selection of lodgings. Sounds good? It is. ... Ko Kho Khao travel guide -
Ko Kradan
A Thai island with so much potential, the beauty and tranquility of Ko Kradan has been squandered over the last decade and it remains best-known for its annual mass underwater-weddings rather than the stunning beach and large coral reef. The view from the beach is spectacular, looking out and over other islands including Ko Muk. If you are in the area, it's definetly worth coming out here -- but for the moment, a day-trip remains the best option ... Ko Kradan travel guide -
Ko Kut
Despite being a beautiful mountainous island with white sandy beaches and crystal blue water, for the independent traveller, Ko Kut can be a difficult destination to explore -- though for some that just adds to the attraction. Popular with Thai package tourists, Ko Kut is a terrific island to escape the hordes of foreign tourists and experience some of the hospitality Thailand is famous for ... Ko Kut travel guide -
Ko Lanta
For a long time Ko Lanta was a little-visited backpacker spot in Thailand, playing second fiddle to the big backpacker magnets of Ko Pha Ngan, Ko Tao and Raileh Beach. But word has finally got out about what a great island Ko Lanta truely is -- with something for just about every budget -- from high class luxury to basic thatch huts. With a less hectic scene, smooth, calm waters and broad beaches, Ko Lanta is particularly popular with those travelling through Thailand with young children ... Ko Lanta travel guide -
Ko Lao Liang
If you're looking for isolation, you'll find it on Ko Lao Liang -- little more than a limestone boulder surrounded by teal Andaman waters. It's a tiny island -- in fact you can easily kayak around it in just over half an hour -- and there's a single white sand beach, set below a cliffside draped in tropical vegetation. If that sounds pretty good, that's because it is. With just the one place to stay -- there's literally not room for anything else -- you needn't worry about overcrowded shores ... Ko Lao Liang travel guide -
Ko Libong
This large island sits quite close to Thailand's southwest coast in Trang province. Little-visited, Ko Libong is much cleaner than some of its neighbours, the people are polite, honest, friendly and eco-minded. Fewer visitors make it here, but those that do are generally well-rewarded. A nice laid back kind of place that doesn't have the jaded feel of some other busier Thai islands. Oh, and there's dugongs here too ... Ko Libong travel guide -
Ko Lipe
A warm, windy island that offers something for most anyone, Lipe's range of accommodation options and fantastic marine life attract a healthy (and rapidly increasing) number of tourists each year. Still, it's easy to find tranquil surroundings here, even during peak season, with several coves and walks through the jungle from one beach to another. Rapidly increasing in popularity, see Lipe now while it still retains some of its beauty ... Ko Lipe travel guide -
Ko Maak
Just to the south of Ko Chang, Ko Maak is a lot less heavily touristed than its big sister -- a great place to go for a bit of quiet and some less crowded beach front: perfect just for chilling out. The two main beaches are sandy, scattered with rock, and sparsely populated with bungalows. The relatively flat interior is covered with coconut palms and a maze of unsignposted dirt roads. A laid-back hideaway ... Ko Maak travel guide -
Ko Muk
Travellers and tourists alike flock to Ko Muk to see the famed Emerald Cove, a somewhat captivating quirk of nature. The quirk aside, travellers who make it to Ko Muk will find an inviting holiday atmosphere, with some of the best value accommodation of all the Trang islands, making it easily accessible to travellers of most budgets. ... Ko Muk travel guide -
Ko Mun Nork
Ko Mun Nork rarely finds itself on the itinerary of roving backpackers and travellers, but ask Bangkokians about it and you'll quickly hear some of the rave reviews Ko Mun Nork receives -- both as a romantic weekend getaway and also for the occasional parties thrown on the island -- parties which are very much invite only. Private label raves and romantic weddings aside, Ko Mun Nork is certainly worth consideration -- particularly on weekdays when you could well have the entire island to yourself. It's a hidden away paradise representing excellent value ... Ko Mun Nork travel guide -
Ko Ngai
The main beach on Ko Ngai is one of Trang's best -- a long sliver of white sand that looks out onto distant limestone karsts -- but as you might expect, it's also one of the province's most developed beaches. While tourism seems to have barely a toehold on other islands dotted off the scenic Trang coastline, it's fully entrenched on Ko Ngai, with barely a yard of beachfront left undeveloped. The trend here is for full service upmarket spa resorts, and the budget options that were once the mainstay of Ko Ngai have been slowly squeezed out. ... Ko Ngai travel guide -
Ko Pha Ngan
Although best known for its full moon parties, which attract thousands of travellers from all over the globe, there is a lot more to stunning Ko Pha Ngan than getting trashed and passing out in the powder-soft white sand. Ko Pha Ngan has swathes of beautiful beaches, great walks, adventurous boat and fishing trips, fabulous diving and even kite-boarding. Equally compelling for many is just spending a few days or weeks in a hammock, watching the sun rise and fall ... Ko Pha Ngan travel guide -
Ko Phi Phi
Ko Phi Phi -- oh what this beautiful island could/should have been. Arguably the most stunning location in Thailand, Ko Phi Phi is home to guest houses, luxury hotels, bars, restaurants, tailors, internet cafes, travel agents, banks, piers, CD shops and clothes markets. Rather than being preserved as a day-tripping destination with pristine walking trails, caving, unspoilt diving and snorkelling spots, Phi Phi is a national disgrace. Despite this, thousands pour onto the island every year and for many, Ko Phi Phi remains the highlight of their trip. Beach solitude can be a little tricky to find, but if you really want to party and meet loads of like-minded souls read on ... Ko Phi Phi travel guide -
Ko Samet
Ostensibly part of a national park, the small island of Ko Samet is the perfect weekend getaway from Bangkok and while this proximity has brought convenience, it has also brought the developers on in hordes. Despite the over-development, it remains a very popular getaway -- on the weekends the beaches are crammed with Thais and expats from the capital along with backpackers and other tourists, while in the middle of the week it is often not difficult to find a beach all for yourself. If you remember that you're on one of the closest islands to a city of ten million people, you'll probably appreciate it more ... Ko Samet travel guide -
Ko Samui
As a popular island destination, Ko Samui is surpassed in Thailand only by Phuket. With an international airport, a mass of ferry connections and close to 500 hotels and guesthouses, this is not somewhere to come to glimpse a corner of the kingdom untouched by tourism development. But if you're hunting for stunning white beaches, turquoise waters and all-day sun, Samui isn't a bad choice. Regardless of whether you want to spend $200 or 200B on a beachfront bungalow there is something on Ko Samui for everyone ... Ko Samui travel guide -
Ko Sukorn
Ko Sukorn is a small island located off the coast of Trang. Home to four small villages, four cars and a handful of small resorts, Ko Sukorn (or Ko Muu as the locals know it) is a great choice for people wanting to escape the crowds of some of Thailand's other great islands. Visitors will have long dark sand beaches pretty much to themselves, along with the spectacular sunsets and great hospitality. A top destination ... Ko Sukorn travel guide -
Ko Tao
Over the years, Ko Tao has been a pirate's hideout, a layover for fishermen, a prison and a badly-kept backpacker secret. Today it is one of Thailand's premier diving locations, attracting thousands of recreational divers and other tourists annually. The island is ranked number two worldwide for the issuing of PADI certificates. Non-divers willing to escape from the congested diver hotspots are rewarded with gorgeous beaches, great viewpoints and hospitable locals. Of course if you are diving, Ko Tao is a must, with some of the best diving in the Gulf of Thailand ... Ko Tao travel guide -
Ko Tarutao
In Malay, Tarutao means old, mysterious and primitive. For many visitors, Tarutao's appeal is in the wildlife: sea turtles, whales, monitor lizards, crab-eating macaques, mouse deer and more all call the island and its surrounding waters home. There's no snorkeling as the waters are murky compared to other Andaman islands, but for most, the clean beaches, waterfalls, great hiking and views more than compensate. For those who are into such things, Ko Tarutao was the location where Thailand Survivor was filmed ... Ko Tarutao travel guide -
Ko Wai
Pretty and primitive, Ko Wai sits about 6kms south of the bottom tip of Ko Chang. White sandy beaches, few people and abundant sealife make the island a favourite hideaway for some travellers fleeing the screaming motorbikes and blaring all-night beats of the larger islands nearby. There are only four bungalow operations on the island -- all on the north side of Ko Wai. It's from this coast that there are terrific views over nearby island ... Ko Wai travel guide -
Ko Yao Noi
Rich in natural beauty, Ko Yao Noi constitutes one of the last bastions of untouched wilderness in the region. There are some paved roads, a lot of them pretty rough, and many more are simply made of dirt. There's plenty of room to roam and explore in this area, and almost anywhere you choose to stay will be in a peaceful setting surrounded by nature. The beach is no good on much of the coast at low tide -- too many rocks and mud flats -- but is largely swimmable at high tide, and a few beaches are good all day long ... Ko Yao Noi travel guide -
Ko Yao Yai
Ko Yao simply means 'Long Island,' which is kind of funny if you're familiar with the one in New York. Ko Yao Yai is 'Big Long Island' and it is indeed big and long. As with Ko Yao Noi, Ko Yao Yai constitutes one of the last bastions of untouched wilderness in the region. There are some paved roads, a lot of them pretty rough, and many more are simply made of dirt. There's plenty of room to roam and explore in this area, and almost anywhere you choose to stay will be in a peaceful setting surrounded by nature ... Ko Yao Yai travel guide -
Phuket
For the budget traveller, the days of grass huts on the beach are largely gone and simple seafood feasts have been replaced by KFC, Starbucks and Pizza Hut. Phuket is an expensive place, with lodging, eating and transport all far costlier than elsewhere in Thailand. The so-called pearl of the south, Phuket is today unrecognisable from just a couple of decades ago. As property prices soared, many locals sold up to national and international hotels and many of the most beautiful beaches are now host to scores of them, along with restaurants, bars, travel agents, massage parlours and the other usual suspects. Despite these negatives, there remains a tantalising side to the island. Windswept beaches you can camp on and not see a soul for kilometres... these hidden-away gems linger -- you just need to look a little harder ... Phuket travel guide

-
Ko Russei
Though only an hour's boat ride from Sihanoukville, Ko Russei is a world away from the manicure/massage/bracelet-toting touts of most mainland beaches. At Ko Russei, there are only golden sands, fishermen's boats offshore, and a cluster of antique Russian guns strategically placed between the beaches. Once they've seen Russei, many travellers want to come back and stay a while, and for those who have -- or make -- the time to stay here, it's often an unexpected highlight of their travels in Cambodia. ... Ko Russei travel guide -
Ko Sdach
This small fishing village island sits at the half way mark between Ko Kong and Sihanoukville and used to be stopped at daily by the bullet-boat. For those interested in experiencing a totally unadulterated stay in a Cambodian fishing village, then this isn't a bad choice. Located just a twenty minute boat-ride off the Cambodian coast, Ko Sdach is dominated by a sizeable fishing village that stretches along the side of the island that faces the mainland, but the real attraction is the outlying islands ... Ko Sdach travel guide -
Ko Tonsay
Ko Tonsay, or Rabbit Island as it is commonly known as, is a lovely little island that sits offshore from Kep, just thirty minutes away be hired boat. The main beach where the boats anchor in lined with coconut palms, hammocks and lazy chairs, a half dozen beach huts and a handful of fresh seafood joints serving up some outstanding seafood ... Ko Tonsay travel guide
Islands in Laos
-
Don Dhet
Now well-established on the traveller trail through Laos, the number of rooms on Don Dhet continues to climb steadily. The scenery is indeed very...well...scenic, and the ambience of the place very relaxed, but Laos this is not. If you're on the way here expecting to experience the local culture, prepare to be very, very disappointed. If on the other hand, all you want to do is relax in a hammock for a week (or a month) meet and talk to travellers and eat traveller food with yet more travellers, then you're in the right place ... Don Dhet travel guide -
Don Khon
Far larger than Don Dhet, Don Khon is skipped by many budget travellers because most of the accommodation is mid-range. However although there aren't 40-odd places to choose from, there are budget options here and staying on Don Khon is far more of a Lao experience than Don Dhet. There are options for cycling and walking and lots of general hanging out watching life flow by -- oh and there are dolphins too ... Don Khon travel guide -
Don Khong
Don Khong is the largest island is the Si Phan Don area, although it is nowhere near as popular as the more southern islands of Don Dhet, with its chilled-out atmostphere, and Don Khon, with more activities on tap. The interior of Don Khong is almost entirely given over to rice cultivation and the major pastime on Don Khong is cycling around the countryside. Expect some interesting little temples and pleasant riverside scenery all wrapped up in a gentle pace of life. ... Don Khong travel guide

Con Dao Islands
Con Dao (also known as Poulo Condore) is an archipelago of 15 islands situated in the South China Sea, around 250 kilometres, or a 45-minute flight, from Ho Chi Minh City. Famed for its grizzly past, Con Son is largely mountainous and covered in forest, with ample opportunity for hiking through the jungle and looking for wildlife. The island is also home to a coastline of steep, rocky hills and long sweeping coves, boasting some excellent spots for swimming and snorkelling ... Con Dao Islands travel guide -
Phu Quoc Island
Sitting back in a hammock, looking out over the quiet surf, you may wonder why more people don't know about Phu Quoc Island. It gets almost none of the press of those islands over in Thailand -- and yet with its rugged jungle, squeaking white sands and sparkling cobalt waters, it can more than match them. We've seen many an island in Southeast Asia, and we've never stumbled across somewhere quite like here ... Phu Quoc Island travel guide -
Cat Ba Island
Nestled on the periphery of Vietnam's fabulous Ha Long Bay, Cat Ba Island is big -- over 350 square kilometres, but most tourists see but a sliver of it. Ths island is a good launching point for kayaking trips, but probably the best way to really see the island is by motorbike -- there's a 100 km circuit running along the bay and into the interior, through incredibly beautiful country-side, and small villages where life in Cat Ba has gone on, largely untainted by the decade-long boom in tourism ... Cat Ba Island travel guide -
Ha Long Bay
A cruise on Ha Long Bay -- or the Bay of the Descending Dragon -- for many represents the pinnacle of their experience in Vietnam. easily one of the most popular destinations in the country, UNESCO World Heritage-listed Ha Long Bay is both mystical and magnificent, an incredible feat of nature that almost never fails to impress. Yes, it really is that good. ... Ha Long Bay travel guide
