General information about the Thailand islands

Hard to believe, but in the south of Thailand there are more than 500 islands and islets to discover! So it is often very difficult to choose the right one. In principle, there are 3 different regions that are ideal for a vacation: The Gulf of Thailand in the west, the Gulf of Thailand in the east and the Andaman Sea on Thailand’s west coast. Each destination has its own special charm and everywhere you will find beautiful dream islands with tropical beaches, some even really lonely and quiet and far away from mass tourism. You should only pay attention to the travel time, because it can be very different depending on the area!


Koh Phangan

Definitely one of the best islands to visit in Thailand is Koh Phangan. This dream island is located in the Gulf of Thailand and is part of the Samui archipelago. It became famous mainly for the Full Moon Party, which takes place once a month in the southeast of the island. Too bad actually, because this dream island has so much more to offer, which means it’s a real insider tip! Especially backpackers, dropouts and yogis, but also demanding individual travelers and luxury vacationers appreciate this island pearl with its many quiet resorts.

Hardly anywhere else in Thailand can you find a larger selection of absolute picture book beaches, where velvety soft sand, tall palm trees and huge round rocks amaze visitors.

Koh Samet

Koh Samet is one of the top recommendations among the most stunning islands of Thailand. This pearl is located on the eastern gulf coast, not far from Pattaya.

Especially the idyllic, snow-white sandy beaches are uniquely beautiful, which create a magnificent backdrop with the turquoise sea and the dense deciduous forests. Other highlights include the exceptionally beautiful temples and impressive statues that are spread across the island, creating a unique ambiance.

Although Koh Samet has become a popular destination for travels from Pattaya and is therefore quite touristy, you can still find lonely dream beaches on this island, some of which you can enjoy almost all to yourself.

Koh Similan

A really spectacular island is definitely Koh Similan. Strictly speaking, it is an archipelago consisting of 9 small islands, one more beautiful than the other. This breathtaking archipelago is located about 60 kilometers off the coast of Khao Lak and inspires with real dream beaches and a breathtaking underwater world. Especially divers and all those who love snorkeling should definitely visit these islands. In order to protect nature, the entire archipelago has been declared Mu Ko Similan National Park and therefore you will not find any accommodations here. You can only visit this group of islands on a day trip, where snorkeling or diving is also offered.

Tip: Trips to the Koh Similan Islands start from Khao Lak or Phuket and can be booked locally or online on GetyourGuide.

Koh Mook

An absolute must-visit is the island of Koh Mook. This natural gem is located near Trang in the Andaman Sea and is a real hidden gem, especially for individual travelers. As part of the Chao Mai National Park, a large part of Koh Mook consists of jungle landscape. Breathtaking dream beaches and still a lot of untouched nature await you on a vacation. The small, quaint village of Baan Koh Mook is also really cute, where you can immerse yourself in the authentic life of the inhabitants. In addition, the island is completely car-free, which makes Koh Mook a really quiet island and gives it an extra dose of charm.

A must-see is Emerald Cave, a former pirate hideout that can only be reached by swimming through a pitch-black tunnel. Also the beaches of the island are breathtaking, especially the paradisiacal Sivalai Beach, probably one of the most beautiful sandy beaches of the country. In addition, there are some great spots around the island to go snorkeling. Sometimes you can even spot clownfish and giant starfish.

Koh Ngai is another pearl of the Andaman Sea and certainly one of the most beautiful islands in Thailand. It is located in the Trang region and already when you arrive by boat you cannot stop being amazed. Turquoise sea, white sand and tall palm trees conjure up an almost kitschy picture book setting. The island is tiny and therefore the perfect place to relax. While doing nothing, you lose yourself in the sound of the sea and only relaxing is the order of the day on this quiet island. If you still want to be active, grab your diving goggles, snorkel and discover the colorful underwater world in the offshore reef or go on excursions to the surrounding Trang Islands!
