Option 1 — Lomprayah Combined Transfer (Recommended)
The Lomprayah combined ferry + airport transfer is the most reliable way to travel from Koh Samui to Surat Thani Airport. One combined ticket via 12Go Asia covers the ferry from Nathon Pier (Koh Samui) to Donsak Pier, then a direct minivan transfer to Surat Thani Airport. All connections are coordinated — if the ferry is delayed, your transfer waits.

Option 2 — Raja/Seatran Ferry + Taxi
The budget option for the Koh Samui to Surat Thani Airport journey is taking a regular car ferry from Nathon Pier to Donsak Pier, then a separate taxi or shared minivan to the airport. Slightly cheaper but requires coordinating two separate bookings and managing the connection yourself.
- Raja Ferry or Seatran from Nathon Pier → Donsak Pier — 80–100 THB, 1h30
- Taxi or shared minivan from Donsak Pier → Surat Thani Airport — 200–350 THB, ~1h15
- Total: ~2h45–3h · ~280–450 THB
If you book the Raja Ferry and airport taxi separately, you're responsible for making the Donsak to Airport connection. If the ferry is delayed by 30+ minutes, you may miss your taxi booking. For important flights, always use the Lomprayah combined Koh Samui to Surat Thani Airport ticket via 12Go Asia.
Option 3 — Private Transfer
For groups of 3+, families or anyone wanting complete peace of mind for the Koh Samui to Surat Thani Airport journey, a private transfer vehicle can be booked from your hotel directly to the airport — including the ferry crossing. The driver handles all logistics. Cost approximately 1,500–2,500 THB for a 4-seat vehicle. Book via your hotel or a reputable Koh Samui transfer agency.
Critical Timing — How Much Time to Allow
The Koh Samui to Surat Thani Airport journey involves multiple legs and timing is critical. Here's a realistic schedule for different flight departure times:
| Flight Departs URT | Latest Ferry Departure from Samui | Recommended Hotel Departure |
|---|---|---|
| 9:00am | 5:00am (Raja/Seatran) or no suitable Lomprayah | 4:00am — very early, consider staying in Surat Thani |
| 12:00pm | 8:00am Lomprayah | 6:30am from Chaweng |
| 2:00pm | 8:00am or 12:00pm Lomprayah | 7:00am (safe) or 10:30am (tight) |
| 5:00pm | 12:00pm Lomprayah | 10:30am from Chaweng |
| 7:00pm | 5:00pm Lomprayah | 3:00pm from Chaweng |
For flights departing Surat Thani Airport before 10am, consider staying overnight in Surat Thani city the night before. The earliest Koh Samui to Surat Thani Airport ferry connection is tight for morning flights. A hotel in Surat Thani city costs $15–30/night and removes all the stress.
