Departure and Arrival Ports
All services leave from Mae Haad Pier, Koh Tao’s main port. On Koh Samui, your arrival pier depends on the operator:
- Maenam Pier, on the north coast, is convenient for Chaweng, Bophut and the airport.
- Bangrak Pier, also on the north coast, is used by Seatran Discovery.
- Nathon Pier, on the west coast, is served by some slower services. If you are staying near Nathon, check whether your ticket includes a hotel transfer, as Songserm often provides pickups.
Schedules
Ferries run year-round. The first departure is commonly around 07:05, and the last leaves between 12:30 and 16:30 depending on the operator and the season. Most services route via Koh Phangan, so allow extra time compared with the direct sailing distance. Timetables can change between seasons, so confirm departure times shortly before you travel.
Which Ferry Should You Choose?
For most travelers, the Lomprayah catamaran from Mae Haad to Maenam is the best balance of speed, comfort and arrival location. The crossing takes about 1 hour 45 minutes and costs roughly THB 600 to THB 750. Travelers on a tighter budget can take the slower Songserm service from THB 450, accepting a longer journey of up to 3 hours 30 minutes.
Booking Advice
Book at least one day ahead in high season, particularly from December to January and around Thai public holidays. Fast-catamaran seats and afternoon departures can sell out.
If you are connecting to a flight from Koh Samui on the same day, choose a morning ferry and leave a generous time buffer. Sea conditions occasionally cause delays or cancellations, especially during the monsoon-affected months.
