The Best Islands in Thailand


There are so many beautiful islands in Thailand that it can be hard to narrow down which to visit first. If you have 10 days in Thailand or less, I’d recommend picking two islands.

Any more and you’ll be rushing from island to island taking overcrowded catamarans and won’t leave enough time to relax. The good news is Thailand’s islands are all quite different so you’ll have plenty to explore and do on any visit!

Below we’re covering 9 of our favorite Thai islands whether you like great beaches, scuba diving or local culture.




Andaman Coast or Gulf Coast?

The first step to deciding where to visit in Thailand is to choose a coast. Thailand has two long coastlines:


Popular Andaman Islands

The Andaman coast is on the outside of the Thai peninsula in the Andamen Sea (near Burma)

Popular Gulf Islands

On the opposite side, to the right of Thailand’s peninsula (sheltered by Cambodia) are the islands:




The Best Thai Islands

1. Ko Samui

Thailand’s Koh Samui Island is for the luxury vacationers. Chaweng, closest to the airport, is the liveliest section of the island with bars, restaurants and sandy beaches. For a secluded paradise, stay in one of the many 5 star resorts with private villas carved into the cliffs – most come with your own infinity pool.

Famous for the all out crazy sloppy fun Full Moon parties, Ko Pha-Ngan is a party pit stop for the wild backpacking crowd. What was once a sleepy bohemian paradise is now more commercialized, but hammock hangers can grab some peace and relaxation on the northern and eastern coasts and live out their modern castaway fantasies.

Railay’s rock climbing scene is legendary, with over 500 routes of limestone walls overlooking crystal blue waters and white sandy beaches. Climbing beginners have nothing to fear while seasone pros will want to try deep water soloing, where the climb ends with a splash into the waves.

When is the Best Time to Visit Thailand?

Here’s a quick guide to the best times of the year to visit Thailand.

  • High Season (Nov – Mar) cool and dry temperatures create a lush landscape and manageable heat. This is the best time to visit the Andaman islands with sunny temperatures and clear diving conditions. Christmas and New Years brings terrible crowds and high prices.
  • Shoulder Season (Apr – Jun) Generally quite hot and dry in Bangkok but there’s a nice sea breeze for relief in the north and coastal areas. This is the best time to visit the Gulf islands.
  • Low Season (Jul – Oct) Both the Andaman and Gulf coasts take turns getting pummeled by heavy monsoon rains. Some islands shut down completely and boat service to and from the islands is limited.




Getting Around Thailand’s Beaches

You can fly from almost all major airports in the region by connecting through Bangkok. Ko Samui has its own airport with direct flights to Hong Kong, Kuala Lumpur and Singapore. Check here for flight deals and book in advance to save on fares.

For connection between the islands, buy a ticket to the Catamaran. You don’t need to buy before you go, but arrive about an hour before the ferry leaves to ensure you’ll get a ticket as they can sell out quickly in the high season. The boats themselves are huge and allow you take luggage on board, but can get topsy turvey on the journey.

For my Thailand trip in June, we stuck to the Gulf islands as the weather is best on that side. We visited Koh Samui and Ko Tao and had an amazing time. For a guide to the best of Thailand, you can check out my two week Thailand itinerary here.

Visiting Thailand – Travel Checklist

The most expensive part of the trip to Thailand are flights. Check for flight deals in advance in order to save. For hotel bookings, we relied on Booking.com.

For more help with planning your vacation to Thailand, we relied heavily on Lonely Planet’s guide. It covers most Thai cities and there is a separate LP guide on Thailand islands. The local advice for admissions, times, maps and pricing was pretty invaluable.

If you plan to scuba dive, kayak or swim – I recommend bringing along a GoPro to take some fun photos!

Finally, make sure to visit Thailand with travel insurance. Whether you get injured and need to be hospitalized, or your phone gets stolen, travel insurance will help when you need it most. Get a quote for your trip here.

      Thanks for the kind words Dominic! It seems like most people get a chance to visit one side of the coast or the other, and I’m definitely hoping to go back to see more islands myself!

    Great read, thanks!

    I’m planning a honeymoon trip to Thailand on the middle of Octoberand only have 10 days. I want to visit the islands and can’t decide which one’s to choose.
    Please help! where do I get a better chance of good weather?

      Hi Shani – unfortunately October is a bit of a difficult month for the islands, as it`s the end of the wet season on the Andaman coast side & the beginning on the Gulf side. have you booked your hotels yet? i would consider heading up north instead, chiang mai and chiang rai have some really gorgeous luxury retreats with views of the rice paddies, forrests, etc. you could do more of a jungle retreat honeymoon (think glamping) as opposed to a rain, wet beach one.
