Insider knowledge

Ferry Tips — What Locals Know

📅
Book in advance during peak season

December-January and Full Moon Party weekends sell out weeks in advance. Always book on 12Go at least 3-5 days ahead during these periods.

🌊
Rough seas October-December

Koh Samui's east coast gets rough seas during monsoon season. Some ferries are cancelled. Check weather and book flexible tickets.

🎒
Overnight bus saves accommodation

The Bangkok-Samui overnight bus + ferry departs at 7-8pm and arrives at 7-9am. You save one night of accommodation costs.

🚗
Only Raja Ferry takes cars

If you're bringing a vehicle from the mainland, Raja Ferry from Donsak is the only car ferry to Koh Samui. Book well in advance.

Arrive 30 min early at the pier

Thai ferry departures are often strict. Arrive at least 30 minutes before departure — especially for the Lomprayah catamarans which leave on time.

💊
Bring seasickness tablets

The crossing from the mainland can be rough, especially in low season. Have Dramamine or ginger tablets ready — pharmacies at the pier are expensive.
