How to Get to Koh Samui: Plane, Ferry, Bus or Train

Getting to Koh Samui is easier than you might think. Although Koh Samui is an island in the Gulf of Thailand, travelers can reach it by direct flight, ferry, or a combination of bus or train and ferry.

The best option depends on your budget, starting point, and how much time you have. Flying directly to Koh Samui is the fastest choice, while traveling through Surat Thani and taking a ferry can be considerably cheaper.

Below, we compare the main ways to get to Koh Samui so you can choose the route that works best for your trip.

1. Fly Directly to Koh Samui

The fastest and most convenient way to reach the island is by flying directly to Samui International Airport. Daily flights operate from Bangkok and other major cities in Thailand. The flight from Bangkok takes about 1 hour, making it the quickest option for travelers with limited time. Although flights can be more expensive than other transport methods, they offer comfort and convenience.

2. Travel by Ferry

Another popular option is traveling by ferry to Koh Samui. Many travelers first reach Surat Thani or Chumphon on the mainland, then take a ferry to the island. Ferries depart regularly and take about 1.5–2 hours depending on the route. This option is more affordable and gives you beautiful views of the Gulf of Thailand along the way.

3. Bus + Ferry to Koh Samui

For budget travelers, taking a bus and ferry is one of the most affordable ways to get to Koh Samui.

From Bangkok, buses travel south toward Surat Thani before connecting with a ferry to the island. Some companies offer combined bus and ferry tickets, making the journey easier to organize.

The trip takes much longer than flying, but it can be a good choice if you want to save money and don’t mind spending more time on the road.

Best for: Budget travelers
Main advantage: Affordable and easy to arrange
Keep in mind: The journey can take most of the day or overnight

4.Train + Ferry to Koh Samui

Koh Samui does not have a railway station, but you can travel by train from Bangkok to Surat Thani and continue to the island by bus and ferry.

Overnight trains are a popular option for travelers who prefer a slower journey and want to avoid spending the entire day traveling. After arriving at Surat Thani Railway Station, continue by road to the ferry pier before taking the ferry across to Koh Samui.

This route takes longer than flying, but the journey itself can become part of the Thailand travel experience.

Best for: Slow travel and overnight journeys
Main advantage: Comfortable alternative to a long bus ride
Keep in mind: You’ll need to transfer from the railway station to the ferry connection
