If you asked a dozen travellers what is the best island in Thailand, there’s a good chance you’ll get a dozen different answers. With so many incredible Thai islands to choose from, finding the best one to suit your style of travel is all down to individual taste. For some travellers, the perfect island getaway will involve staying in a luxury location where the only thing you have to worry about is what cocktail to order at sunset. Others may prefer to go off the grid, forget about Wi-fi and stay in basic beach huts.
Whatever your notion of the perfect holiday island, Thailand has an island that will suit you. In alphabetical order, check out this selection of some of the best islands to stay on your next visit to Thailand.
Ko or Koh?
‘Ko’ is the Thai word for island. It is also written in English as ‘koh’ and both versions can be used. In Thai, the way the ‘k’ is pronounced is somewhere between a ‘k’ and a ‘g’.
Ko Bulon Leh
If you need high-speed Wi-fi and all mod-cons on your travels, Ko Bulon Leh is not for you. But if your idea of paradise is to switch off from the outside world, lay in a hammock amidst the palm trees and gaze out at calm, turquoise waters, then Ko Bulon Leh (often simplified to Ko Bulon) may be just what you are looking for. This lovely little island will be too quiet for some, but for others it represents exactly what a tropical island should be. Home to a small Chao Ley community, Ko Bulon is an island that welcomes a small number of tourists, but retains its soul.

Ko Chang is well-established as a tourist destination and with a broad appeal is an excellent choice for a holiday, whatever your style of travel. Ko Chang is also the ideal base to go island hopping and explore more of the gorgeous Mu Ko Chang National Park. For an insight into local life on the island, prise yourself away from the lure of Ko Chang’s beaches and pay a visit to the community based tourism initiative at Ban Salak Khok.

Located halfway between Krabi Town and Ko Lanta, the small island of Ko Jum (also known as Ko Pu) is a good choice if you’re looking for a tranquil getaway. Stay on the west coast beaches and enjoy views over the Andaman Sea to the Phi Phi Islands in the distance. The opportunity to enjoy the slow life on Ko Jum is what brings visitors here, but if you find it’s too quiet for your liking, it’s easy enough to take a boat to Ko Lanta, Phi Phi or Krabi.

Ko Kood (also written as Ko Kut) is suitable for anybody seeking a laid-back island, but without foregoing any of life’s luxuries. And if it’s luxury you’re after, look no further than the fabulous Soneva Kiri. Try the unforgettable treetop dining experience or relax at the outstanding Six Senses Spa. With jungles and waterfalls to complement its scenic beaches, Ko Kood is similar in appearance to its bigger neighbour, Ko Chang. While Ko Chang has become increasingly developed in recent years, Ko Kood remains a quieter alternative.

There’s little to do on the slender little island of Ko Kradan, but that is part of the appeal.

Ko Lanta is described by many repeat visitors as the perfect Thai island. Easy to reach from Krabi, Ko Lanta offers a choice of attractive beaches and a broad range of accommodation.

Ko Libong may be one of the largest Trang Islands, but it’s also one of the least developed. While the beaches and sea may not be as beautiful as other Thai islands, Ko Libong is an island for nature lovers and anybody interested in enjoying local life. Fishing and farming drive the local economy here and not tourism. Hire a bicycle or jump in a motorbike sidecar taxi to explore the quiet roads and take the opportunity to go on an eco-friendly boat trip to try and spot the elusive dugongs (similar to manatees) who feed on the seagrass near Ko Libong.

Improved transport connections have coincided with a rise in development on Ko Lipe and although it is no longer the ‘untouched’ destination it once was, the views from the diminutive island remain as stunning as ever. The compact size of Ko Lipe means that most locations can be accessed by walking although there are also motorbike taxis with sidecars available to take you around. A 10-minute walk along Walking Street is all that separates the two main beaches of Pattaya Beach and Hat Chao Ley (also known as Sunrise Beach).

Located in Ranong province on Thailand’s Andaman Coast, Ko Phayam is often overlooked by travellers heading to the better-known islands and beach resorts like Phuket and Krabi.

Ko Yao Noi
Within easy reach of Phuket, the charming island of Ko Yao Noi offers a stark contrast to its bigger and better-known neighbour.

Ko Yao Noi and Ko Yao Yai
Ko Yao Yai
A short ferry hop across from Ko Yao Noi brings you to Ko Yao Yai. In Thai, the word noi means small, yai is big and yao is long. So Ko Yao Yai translates as the long big island. Although Yao Yai is bigger than Yao Noi, it is even quieter here and another fabulous location to soak up the scenery. Ride a bicycle along the traffic-free roads that take you past local villages and rubber-tree plantations or jump in a kayak to admire the beauty of the island from the sea.

Last, but by no means least, is Phuket. The largest island in Thailand is a province in its own right and consistently rated by visitors as one of the best islands in Thailand. It’s fair to say that Phuket isn’t everybody’s cup of tea, with its detractors arguing it’s too commercialised. But Phuket’s many fans will say that there is a diverse choice of beaches and an equally diverse choice of things to see and do away from the beach.
