Bangkok to Koh Samet: The Pier, the Boat & Every Route (2026)
Koh Samet is the closest island escape to Bangkok, but the last leg is a boat from Ban Phe. Here is how each route works, and why the car never crosses.
Koh Samet is the island Bangkok goes to when it only has a weekend. It sits just off the Rayong coast, close enough that a Friday-night escape is realistic, yet the map hides one detail every first-timer trips over: you cannot drive there. Every route, no matter how you start, ends the same way — a short boat from the mainland pier at Ban Phe. Here is how each way works, and how to plan the crossing so it feels effortless.
The short version: a private transfer drives you door-to-pier in about 2.5 hours; from Ban Phe you hop on a scheduled ferry or a speedboat. The public bus to Ban Phe is cheapest, self-drive means parking your car on the mainland, and whichever you choose the last leg is always by boat.
The three ways from Bangkok to Ban Phe
| Option | Time to the pier | Rough cost |
|---|---|---|
| Private transfer | ~2.5 hours | Per vehicle, boat bought at pier |
| Bus + boat | 3.5–4 hours | From ~200 ฿ + boat |
| Self-drive | ~2.5 hours driving | Fuel, tolls + mainland parking |
1. Private transfer (door to pier)
A private car collects you from the airport or your Bangkok hotel and drives straight to Ban Phe, the working fishing pier where the Koh Samet boats leave. Because no car ferry serves the island, the transfer is honestly a door-to-pier service — we get you to the boats on time, and you cross the last stretch as a foot passenger. It is the fastest way to reach Ban Phe with no changes, which matters most if you have children, luggage or an evening flight. You pay the driver on the day, and there is no prepayment.
2. Public bus + boat (cheapest)
Buses to Ban Phe leave Bangkok’s Ekkamai (Eastern) terminal through the day, taking around 3.5–4 hours for roughly 200 ฿. Some services run right to the pier; others stop in Rayong town, where you pick up a local songthaew for the final few kilometres. It is the budget route by a clear margin, but you carry your own bags through each change and the timings are looser than a private car.
3. Self-drive
The drive down Motorway 7 and Highway 3 is easy, but remember the golden rule: the car does not cross. You leave it in one of the guarded car parks at Ban Phe — roughly 100–200 ฿ a day — and continue by boat like everyone else. Worth it only if you want your own wheels for exploring the Rayong mainland before or after the island.
The boat from Ban Phe, explained
Two kinds of boat make the crossing. The scheduled ferry is a slow wooden vessel that runs to Na Dan pier on the island in 30–40 minutes for around 70–100 ฿ each way; it leaves through the day but thins out in the evening. The speedboat is quicker and can drop you closer to your beach for roughly 200 ฿ a head, but it usually waits to fill up or runs as a charter. Neither is included in the transfer — you buy the boat at the pier once you know your beach.
Don’t forget the park fee: Koh Samet is a national park, so there is an entrance charge on arrival — about 200 ฿ for foreign adults and 40 ฿ for Thai nationals, collected at a checkpoint near Na Dan. Keep some cash handy so the island welcome is smooth.
Landing late? You have more room than on Koh Chang
Koh Samet is kinder to a late arrival than the bigger eastern islands. When the scheduled ferries stop for the evening, speedboats keep going and can be chartered after hours for a higher fare, so a delayed flight rarely strands you on the mainland. Tell us your arrival time and we set the pickup so you reach Ban Phe while boats are still running — and if you do land very late, Ban Phe and Rayong have plenty of rooms for an easy morning crossing.
So which should you pick?
If you are counting every baht and travelling light, the Ekkamai bus and a scheduled ferry will get you there. For anyone with luggage, a family, or a flight that lands in the afternoon, a private car to Ban Phe takes the guesswork out of the drive and lands you at the pier in good time for the boat — which, on the closest island to Bangkok, is really the only part that needs planning.

Fixed prices, the ferry included where the route needs it, and you pay your driver when you’re picked up, at the start of your trip (not when you reach your destination).
