1. Ko Lipe

Settled by sea gypsies, the island is part of the Adang-Rawi Archipelago, and it’s so tiny that you can walk around it in a bit over an hour! It has fantastic beaches and quite a few accommodation options, from air-conditioned bungalows to rustic grass huts. Colourful coral reefs and numerous tropical fish species inhabit the calm waters around the island, making Ko Lipe a small paradise for snorkelling fans.

2. Ko Chang

If Ko Chang were a person, it would certainly have split personality or at least be bipolar. While the west of the island is bustling with life and full of shops, nightclubs and entertainment opportunities, the east side is a quiet paradise for those looking for a relaxing getaway. On the eastern beaches, you can spend days (and no money) strolling on the shore, collecting seashells or snoozing under a coconut tree.

3. Ko Phayam

If you’re looking to have a taste of “the good life”, Ko Phayam is for you. Dive in the clear blue waters, bathe in the sun, munch on local delicacies and enjoy the best sleep ever in a wooden bungalow, allowing the breeze and the rustling palm trees to guide your dreams. Have a walk through a landscape of hot springs, jungles and waterfalls, and visit one of the famous sea-gipsy villages the island gives home to.

4. Ko Tao

Ko Tao is a highly popular destination for tourists who are into hiking, scuba diving or rock climbing. Fishing enthusiasts will also have a great time on the island, trying to catch barracudas, snappers and marlins. There are also quite a few resorts, nightclubs and bars, but there’s still plenty of space for those looking for a quieter, more relaxed experience in the less developed areas on Ko Tao.

5. Ko Samui

Finally, with more than 1.5 million tourists coming here every year, Ko Samui is certainly the leader on the beach-tourism scene in Thailand. It’s become so popular thanks to its affordability, its white beaches, its family-friendly resorts and the relaxed vibe surrounding everything on the island. It offers something for everybody, regardless of tastes or budget.

Tips for Visiting Thailand’s Islands

Thailand’s islands may look close together on a map, but getting between them can take longer than expected. Ferries, speedboats, domestic flights, and weather conditions can all affect travel times, especially during the rainy season.

A few tips that can make your trip smoother:

  • Travel light if you’re island hopping. Many ferries require passengers to carry their own luggage.
  • Book accommodation in advance during the high season (December to April).
  • Always carry cash, especially on smaller islands where ATMs can be limited.
  • Use reef-safe sunscreen to help protect Thailand’s marine ecosystems.
  • Check weather forecasts before booking boat transfers, particularly during monsoon months.
  • Staying connected makes island hopping much easier, especially when checking ferry schedules, booking transport, or using maps. If you’re planning to visit multiple islands, this eSIM for the Thai islands guide can help you choose the best option before you arrive.

When Is the Best Time to Visit Thailand’s Islands?

Thailand can be visited year-round, but the best time depends on which islands you’re planning to explore.

The Andaman Coast, home to destinations like Phuket, Koh Phi Phi, and the Similan Islands, generally experiences its best weather between November and April.

The Gulf of Thailand, where you’ll find Koh Samui, Koh Phangan, and Koh Tao, tends to have more favorable weather from January through September.

For many travelers, the shoulder seasons of November and March offer an excellent balance of good weather, fewer crowds, and lower accommodation prices.
