Koh Samui is a gorgeous, super-accessible tropical island that’s honestly pretty easy to get to. It has an international airport and a well-organized main pier. You can arrive on direct flights from a bunch of places, by ferry (for the “I’m here for the journey” crowd), or just hop on a quick Bangkok connection.
Where is Koh Samui?
Koh Samui, Thailand’s third-largest island, sits in southeast Thailand in the Gulf of Thailand. It’s about 700 km (435 miles) south of Bangkok and gives visitors that dreamy combo of white-sand beaches and lush, wild-green scenery—plus a nightlife scene that definitely knows how to party. Getting around the island is really easy, and the local airport (which is basically right near the action) makes everything extra convenient.

How to get to Koh Samui from Bangkok
Depends how you like your window views—up in the clouds or down on the ground :-). Here are a few ways to get to Koh Samui from Bangkok:
Domestic flights
Koh Samui is fairly close to Bangkok, and the quickest, easiest way to get there is a direct flight.
Local airlines: The two main airlines operating direct flights from Bangkok to Koh Samui are Bangkok Airways and Thai Airways.
Flight duration and frequency: The flight takes about 70 minutes, and there are several flights per day.
Costs: Estimated ticket prices for a direct flight range from about 3,500 to 6,000 baht, depending on the season and how early you book.
Overland transportation
If you’re looking for a cheaper alternative—or you want to mix in a little sea adventure—there are overland options that combine a bus or train with a ferry.
Bus + ferry: Buses leave Bangkok for Surat Thani, a mainland city opposite Koh Samui. The bus ride to Surat Thani takes about 10–12 hours, then you hop on a ferry to the island for another 1.5–2 hours. Lomprayah offers combined routes that include the ferry and are pretty convenient overall.
Train + ferry: For a calmer, more experience-driven option, overnight trains from Bangkok to Surat Thani are a great choice. The train ride takes about 8–12 hours depending on the train type and arrives at Surat Thani’s main station. From there, you’ll take a short bus ride to the pier, then board the ferry to Koh Samui.
Sea travel — a new ferry 🙂
A newer way to travel between Bangkok and Koh Samui is via a ferry called Seahorse Ferry. The service launched in March 2024 and offers a 24-hour sailing with luxury rooms, restaurants, and even a jacuzzi on deck. You can book a range of accommodation options—from seats starting around 1,500 Thai baht to higher-priced luxury suites, including family rooms.
You can also bring vehicles on the ferry. Sailings run weekly, and you can book tickets through the company’s official Line page.
Here’s a short video about the ferry:

Surat Thani — the overland transit hub to Koh Samui
The port city of Surat Thani plays an important role as a gateway to Koh Samui and other nearby islands like Koh Phangan and Koh Tao. It’s basically the transportation crossroads for anyone arriving overland from different parts of Thailand, with bus, train, and ferry services that are usually synced up with island sailing schedules.
It can also be a cheaper alternative to domestic flights—so it’s worth checking the price of a flight to Surat Thani and comparing it with the cost of flying straight to Koh Samui.

Koh Phangan and Koh Tao are two of the closest islands to Koh Samui, connected by fast ferry routes that arrive at convenient, central piers on Koh Samui.
From Koh Phangan
Sailing time from Koh Phangan to Koh Samui is about 30–40 minutes by speedboat, or about an hour by a regular ferry. Companies like Lomprayah and Seatran run frequent departures throughout the day. Ferries usually arrive at Bangrak Pier or Nathon Pier on Koh Samui, depending on the company and departure time.
From Koh Tao
From Koh Tao, you can reach Koh Samui in about 1.5 to 2 hours, depending on the boat type and weather conditions.

Main piers on Koh Samui:
- Bangrak Pier – Located close to Koh Samui Airport and provides easy access to the island’s northern beaches.

Flight or overland—what’s better?
Getting to Koh Samui can be quick and easy by flying with a stop in Bangkok, or a bit longer if you combine overland transportation with a ferry. The best choice depends on your budget, flight availability, and the kind of trip you’re going for:
Pros of flying with a stop in Bangkok: It’s the fastest route, with the convenience of arriving straight on the island. Perfect if you’d rather skip the boat ride and get there ASAP—and you don’t mind paying for the convenience.
Going overland + ferry: This route is great if you have more flexibility and want to add a little adventure along the way, like stopping in Surat Thani or trying Thailand’s buses and trains. Also a solid pick if you’re traveling on a tighter budget.
3 ferry tips for couples, families, and travelers heading to Koh Samui:
- Most ferries offer decent service and a good comfort level. Still, it’s smart to check the ferry type and company ahead of time.
- Your ferry choice should also depend on the weather—there are seasons when the sea gets rougher, and the ride can be extra bouncy. Better to confirm in advance.
- Comfort also depends on the size of the ferry—smaller, faster boats can feel bumpier, while larger ferries are usually a smoother ride.
