Koh Samet is the closest beach island to Bangkok. The trip runs in two legs: a drive of about 186 km to Ban Phe Pier in Rayong, then a boat across to the island. By private van, the road leg takes about two and a half to three hours, and the ferry adds 30 to 50 minutes. A speedboat cuts the sea crossing to 10 to 25 minutes.
The road leg decides how the whole day feels. A private van picks you up at your hotel or the airport, carries the luggage, and stops at the pier your boat leaves from. Buses from Ekkamai take three to four hours and still leave you to carry bags from the bus stop to the right pier.
How long does Bangkok to Koh Samet take by private van
| Leg | Distance | Time |
| Central Bangkok to Ban Phe Pier | about 186 km | 2.5 to 3 hours by van |
| Suvarnabhumi Airport to Ban Phe Pier | about 177 km | 2.5 hours by van |
| Ban Phe Pier to Na Dan Pier, Koh Samet | short sea crossing | 30 to 50 min by ferry, 10 to 25 min by speedboat |
Friday afternoons and the start of Thai long weekends add time on the roads out of Bangkok. A morning departure lands you at Ban Phe with plenty of boats still running.
Suvarnabhumi Airport to Ban Phe Pier for Koh Samet
Suvarnabhumi sits on the eastern side of Bangkok, already on the way to Rayong. Flying in and heading straight to the island saves the drive back into the city and a night in a Bangkok hotel. A driver meets you at arrivals and goes straight to the pier. Our Bangkok airport transfer service covers pickups at both Suvarnabhumi and Don Mueang.
Bangkok to Koh Samet private van price
GoThai Transport prices every trip per vehicle, not per passenger. Out-of-Bangkok trips start from 3,000 THB per vehicle, and Ban Phe sits further out than the shortest routes, so the quote for Koh Samet runs higher. Tolls and fuel sit inside the quote. Check current rates on the GoThai Transport price page, or message the team with your pickup point and travel date. Pay the driver in cash on the day, or by bank transfer in advance.
For a group of four or five with luggage, one van often costs less per person than bus tickets plus taxis at both ends.
Which Ban Phe pier to use for the Koh Samet ferry
Ban Phe has several piers along the same seafront road, a few hundred metres apart. Each boat company runs from its own pier:
- Nuan Thip Pier is the main departure point for slow ferries to Na Dan Pier, the island’s main arrival point.
- Ban Phe Municipality Pier serves ferries to Na Dan and speedboats.
- Smaller piers along the road run speedboats direct to beaches such as Ao Wong Duan and Ao Prao.
Tell the driver which boat company or beach you plan to use, and the van stops at that pier. Resorts on Koh Samet often run their own speedboat transfers from a specific Ban Phe pier, so check the hotel confirmation before the trip.
Koh Samet ferry and speedboat options from Ban Phe Pier
| Option | Crossing time | Price per person | Lands at |
| Slow ferry | 30 to 50 min | about 100 THB | Na Dan Pier |
| Shared speedboat | 10 to 25 min | about 150 to 500 THB | Na Dan or a beach |
| Private speedboat charter | 10 to 25 min | about 1,800 to 3,000 THB per boat | Any beach |
Koh Samet ferry times
Slow ferries to Na Dan run about once an hour from around 8:00 to 17:00, with schedules shifting by operator and season. Speedboats leave more often and keep running later. Plan to reach Ban Phe by 15:30 at the latest for a relaxed choice of boats.
Buy a one-way ticket. A return ticket ties you to one company’s schedule on the way back, and the next departure from Koh Samet may belong to a different operator.
Koh Samet national park fee
Most of Koh Samet sits inside Khao Laem Ya Mu Ko Samet National Park. Foreign visitors pay 200 THB per adult and 100 THB per child, in cash, at the national park checkpoint past Na Dan Pier or on arrival at the beach. Thai nationals pay 40 THB. Keep the ticket for the length of your stay. ATMs cluster near the Ban Phe piers; withdraw cash before boarding.
Luggage tips for the Bangkok to Koh Samet trip
The van handles the heavy part. Luggage stays in the vehicle from your hotel lobby to the pier entrance, with no transfers on the way. Our guide to choosing a private van in Bangkok for your group shows how many bags each vehicle takes.
The boat leg needs more planning:
- Pack soft bags where possible. Crew load luggage onto the open deck of the slow ferry, and hard cases slide around in rough water.
- Expect to wade on speedboat beach landings. Some beaches have no pier, so passengers step off into shallow water. Wheeled suitcases suit Na Dan Pier arrivals better.
- Use a dry bag for phones and passports. Spray reaches the deck on windy days.
- Leave big shopping at the Bangkok hotel. Many hotels store luggage for guests returning to Bangkok after the island.
- Book a baby seat in advance. GoThai Transport arranges baby seats on request for the road leg.
Best months to travel from Bangkok to Koh Samet
November to April brings the driest weather and the calmest sea for the boat crossing. December to February adds cooler mornings and the busiest weekends.
From May to October, Koh Samet receives less rain than many Thai beach destinations, which keeps it a workable choice in the rainy season. Expect short downpours and choppier water on some days, and check the boat schedule the morning you leave. Thai public holidays fill the island with Bangkok weekenders, so book the van and the hotel early for those dates.
Sample Bangkok to Koh Samet trip plan
A three-day trip from a Bangkok hotel runs like this:
- Day 1, 08:00: van pickup at your Bangkok hotel.
- Day 1, 10:30 to 11:00: arrive at Ban Phe Pier, buy boat tickets, pick up cash.
- Day 1, 11:30: ferry or speedboat to Koh Samet, pay the park fee, check in.
- Day 2: beaches, snorkelling trips and a seafood dinner on the sand.
- Day 3, early afternoon: boat back to Ban Phe, where the van waits at the agreed time for the drive to Bangkok or the airport.
Travellers with an extra day can add a stop in Pattaya on the way, about an hour’s drive from Ban Phe, and continue to the pier the next morning.
Getting back from Koh Samet to Bangkok
Agree the return pickup time and pier when you book. Most boats from Koh Samet arrive at the same Ban Phe piers, and the driver waits there. Allow a buffer of about an hour after the planned boat time, since sea conditions and loading can shift departures. Flights out of Suvarnabhumi on the same day need a generous margin; aim to land at Ban Phe by early afternoon for an evening flight.
