Two car-ferry lines each sail hourly from 05:00 to 19:00 (15 sailings a day each way), taking about 1 hour 30 minutes: Raja Ferry lands at Lipa Noi pier, Seatran Ferry at Nathon pier. Lomprayah adds catamarans from its Laem Thuat pier at Donsak to Nathon at 11:00 and 15:00 (45 minutes), and Songserm a 17:00 speedboat to Nathon (45 minutes).
Raja Ferry adds extra boats at the busy times (05:00–06:00 and 12:00–16:00) when the ferry is full, and in the festival period (30 Dec – 30 Apr) when many vehicles are waiting.
