Last updated November 2026. Koh Samui is an island, so how to get to Koh Samui comes down to two choices: fly straight to the island's own airport, or reach the mainland near Surat Thani and cross by ferry. Flying suits short trips, families and heavy luggage. The mainland route suits budget travelers with spare time. Times below are approximate and come from traveler reports, so confirm them with operators before you book.

|---|---|---|---|---|---|
| Direct flight | One flight, then a short island transfer | About 1 hour in the air from Bangkok | Highest | Families, short trips, peak holidays | You are on a tight budget |
| Fly to Surat Thani + ferry | Flight, bus to pier, ferry | About 4 hours from Surat Thani airport to the island | Middle | Budget travelers who still want to save time | You land late in the evening |
| Bus and ferry combo from Phuket | Bus to pier, then ferry | About 8 to 9 hours | Lowest | Backpackers with a full day free | You have heavy bags or small children |
Flying direct to Koh Samui
A direct flight is the simplest answer to how to get to Koh Samui. Travelers report about one hour in the air from Bangkok and about 55 minutes from Phuket. Fares are often reported as high, especially around Christmas, so book early for peak weeks. Check routes, frequency and baggage rules with the airline before you commit. Our Koh Samui airport guide covers the terminal and arrival process. Reports describe an open-air terminal, so confirm facilities on the official airport pages.
The mainland route: Surat Thani to Koh Samui
This route replaces the expensive flight leg. Fly or travel to Surat Thani, take a bus to the pier, then board a ferry. Travelers report roughly 1 hour on the bus and about 4 hours from the airport to reaching the island. Combined tickets cut the risk of a missed connection, because one operator handles the transfer. Our Surat Thani to Koh Samui guide walks through each leg. Check the Airports of Thailand site for Surat Thani airport details. Then read our Koh Samui ferry guide for pier and crossing choices. Operators such as Lomprayah and Raja Ferry publish timetables. Ferry crossing times vary between sources, so rely on the operator's current schedule.
How to get to Koh Samui from Bangkok
From Bangkok you have three broad options. Fly direct, fly to Surat Thani and cross by ferry, or travel overland. Direct flying saves the most time. Flying to Surat Thani is reported to cost much less than a direct fare, but it adds a bus and a ferry. Overland travel is the longest option. Check the State Railway of Thailand for current overnight train services before planning around one. Details for this corridor are in our Bangkok to Koh Samui guide.
With no direct ferry from Bangkok, one report puts a flight, bus and ferry combination at about 4 to 5 hours.
From Phuket and other islands
From Phuket, the choice is a flight of about 55 minutes or a combo bus and ferry ticket. Travelers report the combo takes about 8 to 9 hours, most of it on the bus. That makes it a full travel day, so do not plan activities for arrival day. Gulf islands such as Koh Phangan and Koh Tao are reported to have regular ferry links to Samui. Confirm current sailings and seasonal changes with the operator before you travel.
Phuket's bus and ferry combo runs 8 to 9 hours, while the mainland route from Surat Thani airport takes about 4 hours.
Once you land: getting to your hotel
Arrival is only half the journey. Islands this size need a plan from the airport or pier to your hotel. Decide in advance whether you want a private taxi or a shared ride. Our Koh Samui songthaew guide explains the shared option. Hotel area affects transfer length, so ask your hotel for a transfer time. Once you are settled, see our guide to getting around Koh Samui.
Mistakes to avoid when planning the trip
Most problems come from tight timing and unchecked details.
- Booking a flight that lands close to the last ferry departure.
- Assuming ferry schedules stay the same all year.
- Naming a pier from memory instead of checking your ticket.
- Choosing the cheapest route when you carry heavy luggage.
- Ignoring sea conditions in the rainy season; check operator notices.
