A peaceful 5-kilometer stretch of golden sand on the northern coast, popular with budget travelers and long-stay visitors. The calm waters make it great for swimming year-round, and the Thursday night market is a local favorite.
Choeng Mon Beach
A small, sheltered bay in the northeast corner of the island known for its luxury resorts and family-friendly atmosphere. The shallow, calm waters and soft sand make it one of the best beaches for young children.

Overnight buses depart from Bangkok's Southern Bus Terminal (Sai Tai Mai) to Surat Thani, then transfer to a ferry. Combined tickets are available. Budget-friendly but a long journey.
Train + Ferry

Overnight sleeper trains from Bangkok's Hua Lamphong station to Surat Thani, then transfer to the ferry pier. A scenic and comfortable option with sleeper berths available.
Flight to Surat Thani + Ferry
2-3 hours
Budget airlines (AirAsia, Nok Air, Thai Lion Air) fly to Surat Thani airport, then take a bus and ferry transfer to Samui. Much cheaper than flying direct to Samui.

Frequently asked questions
When does Koh Samui fit best in an itinerary?
Koh Samui fits best in trips targeting Dec-Mar as the safest broad high-season window. Koh Samui has a different weather pattern from Thailand's west coast. The driest months are December to March with pleasant temperatures around 28-32°C. October and November see the heaviest rainfall and occasional flooding. Unlike the Andaman coast, Samui can still be enjoyable during the southwest monsoon (Jul-Sep) with intermittent sunshine.
Is Koh Samui a good base island?
Koh Samui makes the most sense when you want a Gulf base with room for diving days, slower beach time, or links to neighboring islands. Focus on pace, how many beach days you want, and how much transfer time you are willing to absorb.
Where should you start when planning for Koh Samui?
Start with beaches, stay areas, and arrival logic. That trio tells you faster whether Koh Samui fits your trip than a generic activity ranking does.
