Surat Thani to Koh Samui Ferry and Bus+Ferry Tickets

Surat Thani is where the budget route to Koh Samui comes together: overnight train or bus from Bangkok, then a road leg to Don Sak pier and a ferry across. None of the boats leave from Surat Thani town itself — Don Sak is over an hour away by road — which is why the sensible ticket here is a combo that covers bus and boat in one booking.

We link 12Go because each operator runs a different combination from different pickup points, and the comparison view answers the questions that actually matter: where does it pick up (train station, town or airport), which pier does it land at on Samui, and how long is the total run. Lomprayah’s bus-plus-catamaran combos are the fastest of the standard options, landing at Nathon roughly two to two and a half hours after leaving the train station. Raja (to Lipa Noi) and Seatran (to Nathon) run the no-frills car ferries — cheaper, roughly hourly through daylight hours, but closer to four hours all-in.

Expect roughly 500-850 THB for most full combos, with the fast catamarans at the top — though fares vary widely by operator and season, so compare the live prices. Either way it is a fraction of the cost of flying direct to Samui’s boutique airport, which is the whole point of this route — most travellers doing it have taken the sleeper train down from Bangkok and are trading a slower morning for a much cheaper island arrival.

The one planning rule: leave slack in same-day connections. Trains into Surat Thani run late more often than ferries do, and combo departures taper off from late afternoon. If your train is due at dawn, booking a mid-morning combo rather than the first one keeps a delay from cascading into an unplanned night in Surat Thani.

Once you land, the Koh Samui guide covers the beach zones and things to do on the island. Heading onward to the Full Moon Party island? The Samui to Koh Phangan ferry page covers the short second hop.

Insider Tip: Check which Samui pier your combo lands at. Nathon and Lipa Noi are both on the west coast, a 30-45 minute drive from Chaweng and Lamai — factor the songthaew or taxi leg into your comparison, not just the boat time.

Watch out: In low season some sailings thin out or consolidate. If you are travelling between October and May, confirm the day’s actual departures rather than assuming the high-season rhythm.
