Koh Tao to Surat Thani — Essential Overview
There is no direct ferry from Koh Tao to Surat Thani — the journey always involves passing through Koh Phangan and Koh Samui before arriving at Donsak Pier on the Surat Thani mainland. The Lomprayah high-speed catamaran handles the entire Koh Tao to Surat Thani route as a combined service, making it the most practical and popular option. Total journey time is approximately 3–4 hours depending on connections.
Duration: 3–4h total · Operator: Lomprayah (recommended) · Route: Koh Tao → Koh Phangan → Koh Samui → Donsak Pier · From: 550–650 THB (~$16–19) · Departure pier Koh Tao: Mae Haad · Arrival Surat Thani: Donsak Pier · Book via: 12Go Asia
All Options — Koh Tao to Surat Thani
| Option | Duration | From | Best For |
|---|---|---|---|
| Lomprayah (via Phangan + Samui) | 3h–3h30 | 550–650 THB | Speed · Comfort · Most popular |
| Seatran/Raja (via Koh Samui) | 4h–5h | 400–500 THB | Budget · Stopover option |
| Via Chumphon (Lomprayah north) | 2h to Chumphon | 600–700 THB | Bangkok connections · Train |
Most travellers heading from Koh Tao to Surat Thani are continuing to Bangkok by train or bus. If that's your plan, going via Chumphon is actually faster and more efficient — shorter crossing (2h) and the overnight train from Chumphon to Bangkok is one of Thailand's best travel experiences. See our Koh Tao to Bangkok guide for the complete route.
Option 1 — Lomprayah via Koh Phangan & Koh Samui (Recommended)
The Lomprayah combined service is the definitive way to travel from Koh Tao to Surat Thani. The catamaran departs Mae Haad Pier on Koh Tao, stops briefly at Thong Sala Pier (Koh Phangan) and Nathon Pier (Koh Samui) before arriving at Donsak Pier in Surat Thani Province. The complete Koh Tao to Surat Thani crossing takes approximately 3–3h30 on Lomprayah.

Option 2 — Via Koh Samui then Car Ferry
A more budget-friendly way to travel from Koh Tao to Surat Thani is to take Lomprayah to Koh Samui, then a cheaper car ferry (Raja Ferry or Seatran) from Nathon Pier to Donsak Pier. This saves around 100–200 THB but adds 30–60 minutes to the overall journey and requires you to manage the connection at Koh Samui independently.
- Lomprayah Koh Tao → Koh Samui (Nathon Pier) — ~2h, 650 THB
- Raja Ferry or Seatran Koh Samui → Donsak Pier — ~1h30, 80–100 THB
- Total: ~3h30–4h · ~730–750 THB
If you split the journey into two separate bookings at Koh Samui, you are responsible for making your connection. If Lomprayah is delayed, you may miss your car ferry. The Lomprayah combined ticket from 12Go Asia is safer and not significantly more expensive.

Insider Tips — Koh Tao to Surat Thani
- Take the morning departure — the ~9:30am Lomprayah from Koh Tao arrives at Donsak Pier around 12:45pm, giving you the full afternoon to catch a train, bus or flight from Surat Thani.
- Book combined tickets — book the complete Koh Tao to Surat Thani journey including onward connections via 12Go Asia. Guaranteed connections, zero stress.
- Sea sickness warning — the crossing from Koh Tao via Koh Phangan can be rough May–October. Take Dramamine 30 minutes before boarding at Mae Haad Pier.
- Withdraw cash before leaving Koh Tao — ATMs at Donsak Pier are unreliable. Use Mae Haad area ATMs the day before your departure.
- Consider going via Chumphon instead — if your final destination is Bangkok, going via Chumphon (2h crossing) and taking the overnight train is faster and more scenic than the Surat Thani route.
- Keep your eSIM active — your Thailand eSIM works on the mainland from the moment you arrive at Donsak Pier. Essential for navigation and booking onward transport.
