How to Get to Koh Samui: All Routes and Options
Koh Samui has become one of Thailand’s most sought-after islands, known for its stunning beaches, relaxed vibe, vibrant nightlife, and accommodation ranging from simple guesthouses to luxury resorts. But how do you actually get to the island—especially if you’re coming from mainland Thailand or a nearby island? Here’s what you need to know about flights, ferries, and combined land-sea routes, with real-world insights to help you choose the best way for your trip.
Flights to Koh Samui
Koh Samui is one of the few Thai islands with its own private airport, making air travel the fastest—but not always the cheapest—option.
Flights from Bangkok
Fastest option: Direct flights from Suvarnabhumi (BKK) or Don Mueang (DMK) airports, operated by both international and local airlines, with frequent departures throughout the day.
Editorial tip: If you’re short on time and willing to pay a bit extra, this is the most convenient way to go.
On-the-ground insight: During peak travel seasons (July–August, December–January), book at least two weeks in advance to avoid expensive or inconvenient flight times.
Flights from Southern Airports
You can also fly to Nakhon Si Thammarat or Surat Thani airports, then continue to Koh Samui by shuttle and ferry (see below for details).
Ferries to Koh Samui
Ferries are the backbone of travel to the island—affordable, frequent, and a chance to enjoy the scenery along the way. Note: There are several main departure piers and ferry companies, with significant differences in comfort and speed.
Donsak Pier – The Main Gateway
The most common route combines a bus or train from Surat Thani (or Nakhon Si Thammarat) to Donsak Pier, then a ferry to Koh Samui.
- Surat Thani to Koh Samui: A very popular route with multiple daily sailings.
- Nakhon Si Thammarat to Koh Samui: A great option if you’re coming from the south or west.
Editorial tip: Ferries from Donsak are the largest and most reliable—less bumpy than shorter crossings, with comfortable vessels and better on-time performance (especially when booked via 12Go or Bookaway).
Ferries from Neighboring Islands
If you’re island-hopping, don’t miss these routes:
- Koh Phangan to Koh Samui: One of the fastest and most convenient ways, with especially frequent sailings.
- Koh Tao to Koh Samui: Perfect if you’re starting with diving or wild beaches on Koh Tao and want a smooth transfer.
Editorial tip: Inter-island ferries are relatively short, but seas can be rough during the monsoon season (November–December)—be aware if you’re prone to seasickness.
Ferries from Krabi and Ao Nang
Another option if you’re coming from the Krabi or Railay area is a direct or combined ferry and shuttle route:
- Krabi to Koh Samui: This route includes a bus ride to Donsak Pier, then a ferry to the island.
Editorial tip: Expect at least half a day’s journey. It’s convenient if you want to avoid changing transport too often, but less flexible for those needing a tight schedule.
Combined Land Transport: Bus + Train + Ferry
The Classic Route: Bangkok – Koh Samui
If you’re not in a rush and want to experience Thailand overland, the classic route combines an overnight train or bus to Surat Thani, followed by a shuttle and ferry to the island.
- Bangkok to Koh Samui: Combined routes (bus/train to the pier + ferry), with options for day or overnight travel.
Editorial tip: Overnight trains in Thailand are a unique experience—the beds are comfortable, and you can book ahead via Omio or 12Go. The journey is relaxed and scenic. Buses are faster but offer less legroom and privacy.
Southern Route: Phuket – Koh Samui
If you’re in Phuket and want to get to Koh Samui:
- Phuket to Koh Samui: Combined routes—bus to the pier, then ferry.
Editorial tip: This is a long journey (6–8 hours) with one or two transfers. Best for those looking to save on flights or include multiple destinations along the way.
Which Route Is Right for You?
- Direct flight: Ideal if you value time over cost, or are traveling with children or lots of luggage.
- Combined routes (train/bus + ferry): Perfect for those wanting a local travel experience, to save money, or to see more of Thailand along the way.
- Island ferries: Best if you’re island-hopping and want maximum efficiency.
- Combined journeys from the Andaman region (Krabi/Phuket): Great if your trip starts on Thailand’s west coast.
Practical Summary: Our Recommendations
- It’s highly recommended to book ferry and combined land-sea tickets in advance during high season, especially via platforms like 12Go, Bookaway, Direct Ferries, or Ferryhopper—each offers slight advantages (different ticket types, customer support, etc.).
- During peak season, flights can be pricey but save a lot of time—consider them if your schedule is tight.
- Have a full day for travel? Try the overnight train from Bangkok—it’s a classic Thai travel experience.
- Ferries from Koh Phangan and Koh Tao are fast and comfortable, but if the sea is rough, bring ginger or seasickness remedies.
Koh Samui is waiting—just choose the route that suits you best and get going.
