Cómo llegar a Koh Samui: vuelos, ferris y rutas de autobús

Figuring out how to get to Koh Samui can feel like a puzzle the first time you try it. Thailand’s most famous island after Phuket doesn’t have a bridge from the mainland, so you’re always looking at either a short flight or a combination of bus, train, or ferry to reach those palm-fringed shores. I’ve done the journey several ways over the years, and each route has its own trade-offs between cost, speed, and comfort. Here’s everything I’ve learned, so you can pick the option that fits your trip, your budget, and your patience level.

Getting to Koh Samui: Which Route Is Right for You?

The fastest way to reach Koh Samui is flying directly into Samui Airport (USM), but it’s also the most expensive. The cheapest route involves a bus or train to Surat Thani on the mainland, followed by a ferry across the Gulf of Thailand. Your best choice depends on where you’re coming from, how much time you have, and whether you’d rather save money or save hours.

Here’s the quick version: if you’re coming from Bangkok and money isn’t a major concern, fly. If you’re on a budget, the overnight train or bus to Surat Thani plus a ferry is the classic backpacker route and costs a fraction of the flight. If you’re already in Southeast Asia (Singapore, Kuala Lumpur, Penang), there are direct flights and combo options that make the hop surprisingly straightforward.

I’ll break down every realistic route below, with honest advice on cost, timing, and the little things nobody tells you until you’re standing at a pier at 6 AM wondering which ferry company you booked with.

Flying to Koh Samui: Samui Airport and Airlines

Flying into Koh Samui Airport (USM) is the most convenient way to reach the island, with a flight time of about 70 minutes from Bangkok. The airport is privately owned by Bangkok Airways, which gives it a boutique feel: open-air terminals, tropical garden walkways, and a complimentary snack bar in the departure lounge that makes even budget travellers feel a bit pampered.

Which Airlines Fly to Samui Airport?

Bangkok Airways operates the vast majority of flights into USM. They run the route as a near-monopoly, which is why fares tend to be higher than other domestic Thai routes. Expect to pay anywhere from 2,500 to 6,000+ baht one way from Bangkok, depending on season and how far ahead you book. During peak holidays like Songkran (April) or Christmas/New Year, prices can spike even higher.

Bangkok Airways also flies direct to Samui from Singapore (Changi), Kuala Lumpur (KLIA), Hong Kong, and Phuket. These international routes are a massive time-saver if you’re already in the region. The Singapore-Samui and KL-Samui flights typically run daily, sometimes twice daily in high season.

A few other carriers have come and gone over the years. Thai Airways occasionally operates seasonal routes, and some low-cost carriers have tried flying to nearby airports (like Nakhon Si Thammarat or Surat Thani) with a ground transfer tacked on. But for a direct landing on the island itself, Bangkok Airways is your main option.

Samui Airport: What to Expect When You Land

Samui Airport is small and efficient, and you’ll step off the plane directly into open air. There are no jet bridges here, just a short walk across the tarmac. Baggage claim is quick, and the airport is located right in the middle of the island near Chaweng and Bophut, so you can be at your hotel within 15 to 30 minutes of landing.

Taxis from the airport have a fixed-rate system. Expect to pay around 300 to 600 baht depending on which beach you’re heading to. Chaweng and Bophut are on the cheaper end; Lipa Noi and Taling Ngam on the west coast cost more. There’s no Grab (ride-hailing) at the airport, so the taxi desk is your only option unless your hotel offers a pickup. Shared minivans are sometimes available for a lower rate, but they wait to fill up before departing.

Booking Tips for Flights to Samui

Book Bangkok Airways flights directly through their website if you can. They often run promotions, and their Fly2Save fares (released a few months ahead) can be significantly cheaper than what you’ll see on aggregator sites. Also, keep an eye on their Discovery Airpass, which bundles multiple flights at a discount if you’re doing several legs within Southeast Asia.

If you’re flexible on dates, shifting by even one day can halve the fare. I once saved 3,000 baht by flying on a Tuesday instead of a Sunday. Morning flights also tend to be cheaper than afternoon ones, and they’re less prone to delays during the monsoon season.

Surat Thani to Koh Samui: Ferry and Bus-Ferry Options

If you’re not flying, the gateway to Koh Samui is Surat Thani, a transport hub on Thailand’s Gulf coast about 650 km south of Bangkok. From Surat Thani, you take a ferry to the island. The most common departure piers are Donsak Pier (for car ferries and passenger ferries) and some operators run from Bang Rak Pier near the airport. Journey time on the ferry itself ranges from 45 minutes to 2.5 hours depending on the vessel and operator.

Ferry Operators: Who Runs the Boats?

There are two main ferry companies running the Donsak to Koh Samui route:

Ferry de Raja y Ferry Seatran are the workhorses of this route. Both operate large car-carrying ferries that run hourly from early morning (around 5 AM) through to late afternoon (last departure usually around 7 PM). The crossing takes about 1.5 to 2 hours, and the ferries are stable, air-conditioned, and have food stalls onboard. These are the ferries you’ll take if you’re bringing a vehicle across, which is relevant if you’re riding a motorcycle or driving through Thailand and want to explore Samui on your own wheels.

If you’re planning to ride a motorbike in Thailand (or drive your own vehicle onto the island), you’ll want to make sure your paperwork is in order. An Permiso de conducir internacional is essential for legally operating a motorcycle or car in Thailand, and rental shops on the island will often ask to see it alongside your home licence. Don’t skip this step, especially if you plan to explore beyond the tourist areas.

Lomprayah High-Speed Catamaran

Lomprayah is the premium option, running a high-speed catamaran that cuts the crossing time to about 30 to 45 minutes from Donsak to Koh Samui (Nathon Pier). It’s faster, smoother, and more expensive than the car ferries. Lomprayah also offers combined bus-ferry tickets from Bangkok, Surat Thani town, and even from Koh Phangan and Koh Tao, making it a popular choice for island hoppers.

One thing to watch with Lomprayah: the catamaran can be cancelled or significantly delayed in rough seas, particularly during the monsoon months of October through December. I got caught once in November, and after a three-hour delay they switched us to a slower Seatran ferry. Not a disaster, but worth knowing if you have tight connections.

Bus-Ferry Combined Tickets

This is the budget traveller’s bread and butter. Multiple companies sell combined bus and ferry tickets that take you from Bangkok (or Chumphon, or Surat Thani town) all the way to Koh Samui for a single fare. The bus takes you to the pier at Donsak, and the ferry takes you across to Nathon Pier on Samui. Total journey time from Bangkok is roughly 10 to 14 hours depending on traffic, ferry timing, and sea conditions.

Expect to pay around 600 to 1,200 baht for a VIP bus plus ferry combo from Bangkok. The VIP buses have reclining seats and air conditioning, but I’d recommend bringing a jacket because Thai buses can run the AC cold enough to simulate winter. An overnight bus is a great way to save on a night’s accommodation, though sleep quality depends heavily on the road and your fellow passengers.

Comparison: Routes from Surat Thani to Koh Samui

Here’s how the main ferry options compare so you can pick based on your priorities:

Operador	Tipo de embarcación	Tiempo de cruce	Approx. Cost (one-way)	Sale de	Llega a	Uso recomendado
Ferry de Raja	Car ferry (passenger + vehicle)	1.5-2 hrs	150 to 250 baht (passenger)	Muelle de Donsak	Muelle de Nathon	Budget travel, bringing a vehicle
Ferry Seatran	Car ferry (passenger + vehicle)	1.5-2 hrs	150 to 250 baht (passenger)	Muelle de Donsak	Muelle de Nathon	Budget travel, frequent departures
Lomprayah	Catamarán de alta velocidad	30 a 45 minutos	300 to 500 baht (passenger)	Muelle de Donsak	Nathon or Bang Rak Pier	Speed, island hopping combos
Bus + Ferry Combo	VIP bus + car ferry	10 to 14 hours (from Bangkok)	600 to 1,200 baht (total)	Bangkok / Surat Thani town	Muelle de Nathon	Budget, overnight travel, no flight

A few notes on the table: ferry prices fluctuate with fuel surcharges and season, so treat these as ballpark figures. Vehicle transport on Raja and Seatran costs extra (roughly 500 to 1,000 baht for a motorcycle, more for a car). Lomprayah does not carry vehicles, only passengers, so if you’re bringing your own bike you need one of the car ferries.

Getting to Koh Samui from Bangkok

From Bangkok, you have three main options: fly direct, take the overnight train to Surat Thani and then ferry, or take a combined bus-ferry. The flight is fastest and priciest, while the train and bus options are budget-friendly but take the better part of a day or night.

Option 1: Direct Flight from Bangkok

Bangkok Airways flies from both Suvarnabhumi (BKK) and Don Mueang (DMK) to Samui Airport (USM), though most flights depart from Suvarnabhumi. Flight time is about 70 minutes, and with a quick taxi from the airport to your hotel, you can be on the beach within 2.5 hours of leaving your Bangkok hotel. Fares typically range from 2,500 to 6,000 baht one way. Book early for the best prices, especially in high season (December through March and July through August).

Option 2: Overnight Train to Surat Thani + Ferry

This is my favourite budget route, and honestly one of the more enjoyable journeys in Thailand. You board an overnight sleeper train from Bangkok’s Hua Lamphong (or the newer Krung Thep Aphiwat Central Terminal) to Surat Thani, a journey of about 8 to 12 hours depending on the train. The second-class sleeper berths are comfortable, with clean sheets, a curtain for privacy, and an air-con car that gets you through the night. Fares run around 500 to 1,000 baht for a second-class sleeper, and first-class private cabins are available for around 1,500 baht.

From Surat Thani Railway Station, you take a minibus or songthaew to Donsak Pier (about 1 hour, often included in a combined ticket), then the ferry across to Nathon Pier on Samui (1.5 to 2 hours). Combined train-ferry tickets are sold at the station and through agents, and they sort out the transfer for you. Total cost: roughly 800 to 1,500 baht end to end. Total time: about 12 to 16 hours door to door, but you sleep through most of it.

The overnight train is also a great route if you’re combining Samui with a trip to ThailandEl sur profundo, since the southern rail line continues past Surat Thani toward Yala y conectar Malaysian border. You could break the journey and explore a completely different side of Thailand before hitting the islands.

Option 3: Combined Bus-Ferry from Bangkok

Several companies operate VIP buses from Bangkok’s Southern Bus Terminal (Sai Tai Mai) to Koh Samui, with the ferry crossing included. The journey takes 10 to 14 hours, with most buses departing in the evening and arriving at Nathon Pier the next morning. Fares range from 600 to 1,200 baht depending on the bus class. The VIP buses (24 seats) are more spacious and comfortable than standard buses, and I’d always pay the small extra for the VIP if it’s available.

You can book these combined tickets through travel agencies on Khao San Road, through 12go.asia, or directly at the bus terminal. The Khao San Road agencies are convenient but sometimes add a markup and a hotel pickup that involves a minibus transfer to the actual bus terminal. If you’re trying to save every baht, go directly to Sai Tai Mai.

Getting to Koh Samui from Singapore or Kuala Lumpur

If you’re already in Southeast Asia, getting to Koh Samui from Singapore or Kuala Lumpur is straightforward, with direct flights being the obvious choice. But there are budget alternatives if you’re willing to take the scenic route.

Direct Flights from Singapore and KL

Bangkok Airways operates direct flights from Singapore Changi (SIN) to Samui (USM) and from Kuala Lumpur International Airport (KUL) to Samui. Flight time is roughly 2 hours from either city. Fares vary widely, from around 3,000 to 8,000 baht (roughly 120 to 320 SGD or 200 to 500 MYR) depending on season and booking window.

Scoot, la rama de bajo costo de Singapore Airlines, has also operated flights from Singapore to Samui in the past, and budget carrier schedules change frequently. It’s worth checking current availability on Skyscanner or Google Flights, as new routes appear and disappear depending on demand and season.

The Budget Route: Fly to Surat Thani + Ferry

Here’s a money-saving trick that saves a lot but costs you some time. Instead of flying directly to Samui, book a budget airline flight from Singapore or KL to Surat Thani Airport (URT). AirAsia and other low-cost carriers serve this route, sometimes with a connection through Bangkok or Kuala Lumpur. From Surat Thani Airport, a combined bus-ferry transfer takes you to Donsak Pier and across to Samui. The whole second leg takes about 2 to 3 hours and costs roughly 300 to 500 baht.

I’ve done this from KL: an AirAsia flight to Surat Thani (connecting through Bangkok), then a Seatran ferry. Total cost was less than half the direct Bangkok Airways fare, but the journey took about 8 hours door to door instead of 3. If you have time and want to save money, this is the way. If you’re on a short holiday, just fly direct.

Desde Penang y Otros Malaysian Cities

Si estas en Penang or elsewhere in northern Malaysia, you can take a minibus or train north to Hat Yai en el sur Thailand, then catch a bus or van from Hat Yai to Donsak Pier and ferry across to Samui. The total journey from Penang to Samui is roughly 8 to 10 hours and costs about 800 to 1,500 baht. It’s a long day, but it’s the cheapest option if you’re travelling overland from Malaysia and don’t want to fly.

From Koh Phangan and Koh Tao (Island Hopping)

If you’re already in the Gulf of Thailand islands, getting to Samui is simple. Lomprayah runs high-speed catamarans between Koh Tao, Koh Phangan, and Koh Samui, with crossings taking 30 to 60 minutes between each. Seatran also operates ferry services between the islands. From Koh Phangan to Samui specifically, the trip is just 20 to 30 minutes by Lomprayah, making it one of the shortest ferry crossings in the region.

Tips for Arriving in Koh Samui Smoothly

Knowing how to get to Koh Samui is half the battle. The other half is arriving without stress, confusion, or a surprise 800-baht taxi ride. Here are the practical things I wish someone had told me before my first trip.

Know Which Pier You’re Arriving At

Most ferries arrive at Nathon Pier on the west coast of Samui. This is the main ferry terminal, and it’s where Raja, Seatran, and most Lomprayah services dock. Nathon has taxi stands, minivan connections, and a few shops. But Lomprayah sometimes uses Bang Rak Pier on the north coast (closer to the airport and Bophut), so check your ticket carefully. Your onward transport to your hotel will differ by about 20 minutes and several hundred baht depending on which pier you land at.

Have Baht Ready Before You Land

There are ATMs at Nathon Pier and at the airport, but the queues can be long when a full ferry arrives, and occasionally machines run out of cash. Bring enough Thai baht for your taxi or minivan to your hotel, plus your first meal. Taxis from the pier operate on fixed rates (similar to the airport), typically 300 to 700 baht depending on your destination beach.

Avoid the Late-Night Arrival Trap

The last ferry from Donsak to Samui departs around 7 PM, and if your bus or train is delayed, you might miss it. This happens more than you’d think, especially during the rainy season when road conditions can slow things down. If you’re booking a combined ticket, ask about the guaranteed connection policy. Some operators will put you on the next morning’s ferry for free, but others won’t. I once spent an unplanned night in a Surat Thani guesthouse because my train was two hours late and I missed the last boat. Budget an extra 500 baht for this possibility, just in case.

Descargar mapas sin conexión

Mobile data in Koh Samui is generally good, but there are dead spots in the interior hills and on some western beaches. Download offline maps in Google Maps or Maps.me before you arrive so you can navigate to your hotel even without a signal. This is especially useful if you arrive at a pier and jump in a taxi, so you can verify the driver is taking you the right way.

If You’re Riding a Motorcycle to Samui

For overlanders and motorcycle travellers, you can ride your bike onto the Raja or Seatran car ferry at Donsak. The process is simple: buy a vehicle ticket at the pier, ride onto the lower deck, and secure your bike (bring your own tie-downs or ask the crew for help). The fare for a motorcycle is usually around 500 to 1,000 baht including the rider. Once on Samui, the island has decent paved roads, and exploring by bike is one of the best ways to see the less-visited corners. If you’re renting a scooter on the island instead, the same advice about carrying an Permiso de conducir internacional applies: police checkpoints do happen, and the fines for riding without proper documentation are not cheap.

¿Qué sigue en tu Thailand Island Hop?

Once you’ve sorted how to get to Koh Samui, the rest of your island adventure tends to fall into place. The island is a fantastic base for exploring the Gulf of Thailand, with easy ferry connections to Koh Phangan (for the famous Full Moon Party or its quieter beaches) and Koh Tao (for some of the best diving in Southeast Asia). You could even hop north to explore central Vietnam’s coast, starting with Da Nang and its surroundings, if you’re building a broader Southeast Asia itinerary.

My advice: spend at least four or five days on Samui itself before island-hopping. The island has a reputation as a package-tourist destination, and parts of Chaweng can feel that way, but the west coast (Lipa Noi, Taling Ngam) is genuinely peaceful, and the interior has waterfalls, viewpoints, and jungle roads that most visitors never see. Rent a scooter, take the ring road, and you’ll find a quieter, more real Koh Samui hiding behind the resorts.
