Short answer: Fastest is a direct flight into Koh Samui Airport — about 1 hour 10 minutes, though fares tend to be higher. The budget route is to reach Surat Thani by plane, train or bus, then take a ferry across to Samui, which together takes several hours to overnight.
Your travel options
| Mode | Duration | Cost | Notes |
|---|---|---|---|
| Direct flight to Samui | ~1h 10m | ฿฿–฿฿฿ | Most convenient; pricier fares |
| Fly Surat Thani + ferry | ~1.5h fly + ferry | ฿฿ | Cheaper than flying direct |
| Bus/train + ferry | ~12–15h | ฿ | Combined overnight bus/train + ferry tickets |
Which should you choose?
If budget is no issue and you want to arrive fast, the direct flight to Samui saves the most time. To save money, fly into Surat Thani (cheaper, frequent flights) then take the ferry — a popular combo. Combined overnight bus-and-ferry tickets are cheapest but more tiring.
