Koh Samet is the closest real beach island to Bangkok, and you reach it without a car, a flight, or a tour package. A bus or minivan from Ekkamai runs to Ban Phe pier in about three hours. A short ferry finishes the job.
The whole trip costs around $9 (THB 300) before the island park fee, and it moves faster than the drive out of Bangkok usually lets anything move. The catch sits at the pier on the far end, where fares get quoted well above what locals pay. Learn the two legs and the real prices, and the route is genuinely easy. This guide is built for anyone doing the trip independently. If you would rather skip the terminal and the pier haggling, a private transfer is covered further down.

The route is two legs with one break in the middle. You cover land to Ban Phe, then water to the island. Nothing needs booking in advance outside a holiday weekend.
- Total time: about 3.5 to 4.5 hours door to door, roughly 3 hours to Ban Phe plus a 10 to 40 minute crossing.
- Total cost: around $9 (THB 300) for bus or van plus the slow ferry, before the park fee.
- Leg 1: Ekkamai (Eastern) Bus Terminal to Ban Phe, bus or minivan, from about $6 (THB 200).
- Leg 2: Ban Phe to Koh Samet, slow ferry $3 (THB 100) return, or speedboat about $6 (THB 200) one way.
- Park fee on arrival: $6 (THB 200) per foreign adult, $3 (THB 100) per child, paid at Na Dan pier.
- First and last boats: slow ferries run roughly 08:00 to 18:00, the last speedboat leaves Ban Phe near 17:00.
Those crossing prices are the honest public fares, not the numbers a counter tout will lead with. We will come back to that on the pier. First, the land leg out of Bangkok, which is the part that actually eats your morning.
The Ekkamai to Ban Phe leg by bus or minivan
Both the bus and the minivan leave from Ekkamai Eastern Bus Terminal, next to the Ekkamai BTS stop. That location matters. You skip a cross-town taxi and step off the train more or less at the departure gate. Buy the ticket at the counter inside, not from anyone who approaches you on the concourse. You can also pre-book the seat and check current departures on the Bangkok to Ban Phe route page.
By public bus
Cherdchai Tour runs the coach service to Ban Phe for about $6 (THB 200). The seats are wide and the aircon is strong. The trade is frequency. Buses leave only every 90 minutes to 2 hours, so a missed departure means a real wait. Heavy traffic out of the city can also stretch the ride toward five hours (Travelfish, 2026). If you have a fixed departure slot, this is the roomiest way to reach the coast.
By minivan (rot tu)
The minivans leave far more often, roughly every 40 minutes, for a similar fare of about $6 (THB 200). Pick this when you want to leave now rather than wait for the next coach. The downside is space. Seating is cramped, and driving on this run can be brisk (The Blond Travels, 2026). It works for a light packer on a tight clock, less so for a family with luggage.
Ban Phe to Koh Samet by slow ferry or speedboat
Ban Phe is a small pier town, and the island is about six kilometers offshore. You have two ways across, and the right one depends on your budget and your patience. Both drop you a short walk or songthaew ride from the beaches. Check live crossings on the Ban Phe to Koh Samet route page.
The slow wooden ferry
This is the local boat and the consensus best value at $3 (THB 100) return. The crossing takes 30 to 40 minutes and lands at Na Dan, the main pier on the north end. In high season it runs close to hourly through the day. In the quieter May to October stretch it often waits until it fills, so you may sit at the pier for up to an hour before it moves (Travelfish, 2026). Bring water and take it in stride.
The speedboat
A shared speedboat runs about $6 (THB 200) one way and takes 10 to 15 minutes. It can also drop you closer to a specific beach rather than only at Na Dan. This is the pick when the slow ferry wait is not worth it or you are chasing a check-in time. The honest speedboat fare sits near THB 200. If a counter quotes you far above that, walk to the next window.

Koh Samet sits inside Khao Laem Ya National Park, so there is a genuine entry fee on arrival. It is $6 (THB 200) for a foreign adult and $3 (THB 100) for a child, collected at a booth near Na Dan pier. Keep the ticket. Rangers do check it, and it covers your stay rather than a single day. This fee is real and separate from your boat ticket, which is exactly why the boat counters are worth reading carefully.
How to pay the real fare at Ban Phe pier
The route is simple, but the pier is where money leaks. Independent guides and Thai forums describe the same pattern year after year. The boats are easy, and the ticket counters are where travelers get quoted more than the going rate (TripAdvisor, 2026). Thai visitors report the same on local forums, including being asked for THB 150 on a THB 100 ferry (Pantip). None of it is dramatic. It is just a few hundred baht that you keep by knowing the numbers first.
Three habits cover you. Know the fares before you arrive$0 100 return on the slow ferry and around THB 200 for the speedboat. Pay the national park fee only at the official booth by the pier, never bundled into a boat ticket. If a first counter leads with an inflated number, simply try the next window, since Nuan Thip pier is the busier and more transparent option most travelers use.
When a private car transfer is worth the money
A private door to door transfer runs from roughly $65 (THB 2,200) and up, several times the bus-and-ferry cost. For a solo traveler it rarely makes sense. For a group of four with luggage and kids, split four ways, it starts to look reasonable. It removes the terminal, the wait, and the pier haggling in one move. You still cross the last stretch by boat, since no cars go to the island. You can price a private run on the Bangkok to Koh Samet transfer page.

The return mirrors the trip, with tighter timing on the water. The slow ferry from Koh Samet runs to about 18:00, and some piers push to 19:00 in high season. The last speedboat out of the island generally goes by early evening. Aim to be at the pier with a buffer, because missing the final boat means an unplanned night on the island.
From Ban Phe, buses and minivans back to Ekkamai run through the afternoon and early evening, and the last services leave around dinnertime rather than late at night. If you are cutting a return the same day close, take the speedboat off the island to bank time for the land leg. A relaxed traveler does not do Koh Samet as a day trip from Bangkok, since over three hours each way leaves only a few hours of sand. One night on the island is the difference between a slog and a genuine break.
Where to stay when you reach Koh Samet
Most travelers base themselves along the northeast beaches. Hat Sai Kaew sits nearest Na Dan and runs the liveliest. Ao Phai and Ao Nuan are quieter, a short songthaew ride south. The island runs on small resorts and bungalows rather than certified chain hotels, so book the beach that matches your pace. Pairing the island with time in the capital is easy. Our roundup of the best SHA hotels in Bangkok covers the city end. The 3 days in Bangkok itinerary slots neatly before or after the beach.
