How to Get to Koh Samui: Flights, Ferries & Fun Routes

(Updated for 2025)

So, you’ve decided to visit Koh Samui – the dreamy tropical island with swaying palm trees, white sandy beaches, and coconut shakes that taste like sunshine.
Now the big question is: how do you actually get here?
Don’t worry – I’ve got you covered. Here are all the ways you can make your way to this little paradise.


1. By Plane – The Fast & Fancy Way ✈️

Flying is by far the quickest and most comfortable way to get to Koh Samui.
The island has its own Koh Samui International Airport (USM) – one of the cutest airports in the world, complete with open-air walkways and tropical gardens.

From Bangkok

  • Direct flights: Around 1 hour 15 minutes.
  • Airlines: Bangkok Airways (exclusive operator), Thai Airways.
  • Tip: Bangkok Airways often includes lounge access with snacks, drinks, and Wi-Fi – even for economy passengers!

From Other Cities

  • Chiang Mai: ~2 hours direct
  • Phuket: ~1 hour direct
  • Singapore / Hong Kong: International flights available seasonally

💡 Pro tip: Book early if you’re coming during Christmas, New Year, or July–August. Prices can double!


2. By Ferry – The Scenic Route ⛴️

If you love the idea of watching the sea slowly get bluer and the breeze in your hair, the ferry might be for you.

Main Ferry Ports to Koh Samui:

  • Surat Thani (Don Sak Pier) – The most popular departure point. Ferries run every hour, taking 1.5 hours to reach the island.
  • Chumphon – A less common route, but useful if you’re coming from the north.
  • Koh Phangan / Koh Tao – Easy island-hopping connections.

Ferry Companies:

  • Raja Ferry – Bigger boats, can take cars.
  • Lomprayah – High-speed catamaran, faster and more comfortable.
  • Seatran Ferry – Reliable and spacious.

💡 Pro tip: Bring sunglasses and a light jacket – it can be sunny and breezy at the same time.


3. By Train + Ferry – For Slow-Travel Lovers 🚆

If you’re not in a rush, you can combine a night train from Bangkok to Surat Thani with a ferry to Koh Samui.
It’s budget-friendly, eco-conscious, and gives you a taste of Thai countryside life.

How it works:

  1. Overnight train from Bangkok’s Hua Lamphong station to Surat Thani (8–10 hours).
  2. Bus or minivan to Don Sak Pier (1.5 hours).
  3. Ferry to Koh Samui (1.5 hours).

💡 Pro tip: Book a sleeper berth in advance. It’s way more comfortable than a seat, and you’ll wake up almost at the seaside.


4. By Bus + Ferry – Cheapest Option 🚌

For backpackers or anyone on a tight budget, this is the go-to method.
You can book combined tickets from Bangkok, Hua Hin, or other southern cities.

Typical travel time from Bangkok:

  • Bus to Surat Thani: 10–12 hours overnight
  • Transfer to ferry + ferry to Samui: 2–3 hours

💡 Pro tip: Bring snacks, download a Netflix series, and pack a neck pillow.
