The distance between Koh Samui and Phuket means the journey involves more than a single vessel. The fastest option is by air, roughly one hour between Samui Airport and Phuket International — several flights operate daily. If you prefer to travel overland, a combined coach-and-ferry service connects the two destinations via the mainland, with the ferry leg crossing from the Gulf of Thailand toward the Andaman coast.
Planning your journey
Departures on this corridor run throughout the day, with the earliest options leaving before 05:00 for the overland routes. Fares start from THB 787, with air being the premium choice and the coach-ferry combination offering a more affordable alternative. There are around 40 departures daily across all modes, so connections are straightforward to arrange whichever option you choose.
We recommend booking in advance during Thai holidays and the November–April high season, when capacity fills quickly on both the flights and the bus-ferry combinations.
