How to Get to Koh Samui: A Guide From Across Thailand

Koh Samui is Thailand's second-largest island, drawing travellers with its powdery white beaches, clear tropical waters and sacred temples. The fastest and most effortless way to get there is to fly directly into Samui International Airport (USM).

If you would rather keep your travel budget lower, however, it is easy to combine flights, buses and ferries instead. Below is a practical guide to how to get to Koh Samui from some of Thailand's most popular destinations in 2026.

1. How to Get to Koh Samui: A Quick Look Before You Choose

Unlike many destinations in Thailand, Koh Samui is separated from the mainland with no road or rail bridge connecting directly to the island. This means every journey follows one of two basic patterns: fly directly into Samui International Airport (USM), or travel to a mainland or island ferry terminal and complete the final stretch by sea.

For overland travellers, Surat Thani is the main gateway, with road transfers continuing to Donsak for ferries to Koh Samui. If you are already travelling through Koh Phangan or Koh Tao, you can skip the mainland entirely and take a direct ferry or high-speed boat to the island.

2. Flying to Koh Samui – The Fastest and Easiest Way

Samui International Airport (USM) is located directly on the island, making flying the most convenient way to reach Koh Samui without adding road transfers or a ferry crossing. Direct services connect Samui with several major destinations in Thailand, including Bangkok, Phuket, Krabi and Chiang Mai.

From	Flight Time	Indicative Fare	Best For
Bangkok	~1 hr 5 mins	From ~THB 2,730	Fastest and most convenient
Phuket	~55 mins	From ~THB 2,575	Combining two beach destinations
Krabi	Direct flight available	Varies by date	Avoiding a long overland transfer
Chiang Mai	~1 hr 45 mins	Varies by date	Long-distance travel from Northern Thailand
Surat Thani	Fly to URT, then transfer + ferry	Usually lower overall	Budget-conscious travellers

For most travellers, flying directly to Samui is worth considering when time and convenience matter more than price. Bangkok is the easiest starting point, with flights from either Suvarnabhumi Airport (BKK) or Don Mueang Airport (DMK), while Phuket and Krabi are particularly convenient if Koh Samui is part of a wider southern Thailand itinerary. From Chiang Mai, flying also saves a significant amount of time compared with travelling overland.

The main drawback is price. Direct flights to Samui are usually more expensive than reaching the island via the mainland. If you are travelling on a tighter budget, flying to Surat Thani Airport (URT) and continuing with a combined shuttle and ferry ticket can be a better-value alternative. It takes longer and involves more transfers, but it avoids the much longer overnight bus journey from Bangkok while keeping overall costs lower.

3. Take an Overnight Train and Continue by Ferry

Koh Samui has no railway, so train travel only takes you as far as Surat Thani. From there, continue by minivan or bus to the ferry terminal before crossing to the island. This is a slower but more affordable option, especially if you enjoy overnight train travel and want to save the cost of one night's accommodation.

• Departure: Krung Thep Aphiwat Central Terminal, Bangkok

• Train arrival: Surat Thani Railway Station, Phunphin

• Continue by: Minivan/bus → ferry → Koh Samui

• Total journey: Around half a day to overnight

• Combined ticket: Around USD 44–53

• Indicative budget: Approximately THB 1,450–1,800, depending on seat or sleeper class

• Best for: Travellers with more time who prefer an overnight train and a more budget-friendly journey

4. Bus or Minivan + Ferry With a Combined Ticket

This is one of the most popular options for independent travellers and anyone travelling when flight prices are high. If you are leaving from Bangkok or one of the southern provinces, buying a combined ticket that includes both the bus or minivan and the ferry makes the journey much easier to manage.

• From Bangkok: Buses commonly leave from Southern Bus Terminal or the Khao San area. The journey usually takes around 11–17 hours, often overnight, and costs approximately THB 1,300–1,750 per person.

• From Phuket: A van or bus travels across southern Thailand towards Surat Thani before connecting with a ferry from Donsak. Allow around 6.5–10 hours, with basic tickets starting from approximately THB 700 and higher-priced packages available with hotel pickup or high-speed catamaran connections.

• From Krabi: The shorter distance makes this journey considerably easier, usually taking around 4–6 hours. Combined tickets generally range from approximately THB 500–1,000.

• From Surat Thani: If you are already at Surat Thani Airport, the railway station or in the town centre, you can simply purchase a combined transfer taking you towards Donsak and onward to Koh Samui.

5. Taking a Ferry to Koh Samui From the Mainland and Nearby Islands

Whether you have travelled across the mainland or are arriving from another island, the ferry is the final piece of many journeys to Koh Samui.

If you are already in Surat Thani, Koh Phangan or Koh Tao, this part of the trip is relatively straightforward. Depending on your schedule and budget, major operators include Seatran Ferry, Raja Ferry, Lomprayah, Seatran Discovery and Songserm.

5.1 From Donsak Pier, Surat Thani

• Seatran Ferry: Operates from Donsak to Nathon Pier on western Koh Samui. The crossing takes around 1.5 hours, with passenger fares at approximately THB 190.

• Raja Ferry: Operates from Donsak to Lipa Noi Pier in the southwest of the island. The journey also takes around 1.5 hours, with passenger fares at approximately THB 190.

Before choosing a ferry simply by price or departure time, check where your accommodation is located. Arriving at a pier on the opposite side of the island can add both time and a considerable taxi fare to the final part of your journey.

5.2 From Koh Phangan

This is a very short crossing, with high-speed boats and ferries generally taking around 20–45 minutes. Fares begin from approximately THB 250, and services may arrive at Bangrak, Nathon or Pralarn Pier in Mae Nam depending on the operator.

5.3 From Koh Tao

Koh Tao sits farther from Samui, so the journey takes longer. Faster ferry services usually take around 1 hour 30 minutes to 2 hours, while other services may take longer if they stop at Koh Phangan on the way.

Fares in August 2026 begin from around THB 500, with operators including Lomprayah and Songserm serving the route.

If your island itinerary follows Koh Tao → Koh Phangan → Koh Samui, choosing services within the same ferry network can make the connections feel much smoother.

6. Where Will You Arrive in Koh Samui?

Koh Samui has several ferry piers located along different parts of its coastline. Knowing exactly where your ferry arrives makes it much easier to plan the final transfer to your hotel.

• Nathon Pier – West Coast: One of the island's main ferry hubs, used by services including Seatran Ferry, Lomprayah and Seatran Discovery.

• Lipa Noi Pier – Southwest: The arrival point used by Raja Ferry for its Donsak route.

• Pralarn Pier, Mae Nam – North Coast: A key Lomprayah high-speed ferry pier and particularly convenient if you are staying in northern Koh Samui.

• Bangrak Pier – Northeast: Close to Samui Airport and Big Buddha, with high-speed services connecting Koh Samui with Koh Phangan and Koh Tao.

Before paying for your ticket, always check the arrival pier as well as the price and departure time. A slightly cheaper ticket may not save much in the end if you arrive far from your accommodation and need a longer, more expensive transfer across the island.

7. A Private Hillside Wellness Escape at Mantra Samui Resort

After a flight, overnight train or hours spent crossing the mainland and sea, Mantra Samui Resort offers a peaceful place to settle into island life from the green hillsides of Mae Nam. The resort is around 15 minutes by car from Samui International Airport under normal traffic conditions, with Maenam Beach, Bophut and Fisherman's Village also within easy reach.

Set above the coastline, Mantra Samui combines a sense of privacy with sweeping ocean views, creating a quieter kind of Koh Samui stay for adults who want more than simply a place to sleep. As an adults-only, pet-friendly lifestyle and wellbeing resort, its amenities are designed to make slowing down feel like a natural part of the holiday:

• Spacious rooms and suites with panoramic ocean or tropical views and room to properly settle into the stay.

• Ocean-view infinity pool surrounded by tropical greenery, ideal for slow mornings and unhurried afternoons above the coastline.

• Jai Spa, offering a peaceful space for Thai massage, body treatments, facials and time to recharge after travelling or exploring the island.

• SAOL Wellness Retreat, Mantra Samui's more immersive wellbeing experience for guests looking to dedicate several days to movement, recovery and restoration.

• Yoga, Pilates and wellbeing activities, offering lighter ways to stay active without turning the holiday into a strict routine.
