The Koh Samui Ferry piers serve as the vital maritime artery connecting mainland Don Sak in Surat Thani Province to the island of Koh Samui. The operations are primarily managed by two major concessionaires: Seatran Ferry and Raja Ferry (Public Company Limited). These operators utilize large Ro-Ro (Roll-on/Roll-off) vessels specifically designed to transport both foot passengers and a wide range of vehicles, including motorcycles, private cars, and heavy-duty logistics trucks. This ferry system is not only the backbone of the island’s tourism industry but also essential for the daily supply chain, ensuring that goods and resources reach the island efficiently.

In terms of operation, the crossing typically takes between 90 minutes to 2 hours, depending on sea conditions and the specific vessel. Seatran Ferry operates its route to Nathon Pier, which is the administrative and commercial heart of the island’s west coast. Meanwhile, Raja Ferry berths at Lipa Noi Pier, located slightly further south. Both terminals are equipped with organized vehicle staging areas and comprehensive ticketing systems. In recent years, both companies have integrated digital booking platforms, allowing travelers to reserve vehicle slots in advance—a practice highly recommended during peak seasons, such as Songkran or the year-end holidays, when demand for vehicle transport often exceeds capacity.

Facilities onboard are tailored for short-haul comfort and safety. Passengers can choose to stay in spacious, air-conditioned lounges or enjoy the sea breeze on the upper observation decks, which offer panoramic views of the Gulf of Thailand’s archipelago. Each vessel features a convenience kiosk selling snacks, beverages, and travel essentials. Restrooms are available on multiple levels. Crucially, all operations adhere to the strict safety regulations set by the Marine Department of Thailand; ships are equipped with sufficient life jackets for all passengers, visible emergency signage, and inflatable life rafts, ensuring a high standard of maritime safety for the thousands of locals and international tourists who cross the channel daily.
