They’re known for their efficient ticketing service, timely arrivals, and smooth crossings. The boats themselves are also worth a mention. Inside are rows of comfy seats in air-conditioned communal cabins. Outside are breezy deck areas where you can gather with other travelers to watch the mangrove forests roll on by as you sail.

Surat Thani to Koh Samui by high-speed ferry

The most common sort of link between Surat Thani and Koh Samui is the high-speed ferry. But don’t let the name fool you – they aren’t quite as quick as the catamarans. Yes, the crossing from mainland to island is only 1.5 hours on average. However, the boats leave from a pier in Donsak, further east down the coast from Surat Thani, meaning you’ll need to drive for longer before anchors aweigh.

Still, this is a popular option for travelers who want to save a little baht for the massages and bucket cocktails, but also want to arrive in Samui without wasting a whole day on the road. Most journey times are around three to five hours in total, including minivan transfers from either Surat Thani’s downtown or the local airport, pre-boarding waits at the port, and the trip across the shimmering waters of the Thai Gulf.

The high-speed ferry might do the crossing in 1.5 hours, but it leaves from a pier slightly further from Surat Thani itself.

The two best-known names offering high-speed links are Seatran Discovery and Songserm. The former boasts the most modern boats. They’ll whisk you to the north shore of Samui, to Bangrak Pier – a great option if you’re making for hotels in the fisherman’s village of Bophut or gorgeous Lamai Beach. Songserm’s service will drop you at Nathon on the west coast of the island, which is better for accessing the yoga retreats on the south shore and the resorts of quieter Maenam.

It’s always a good idea to book your tickets on the high-speed ferries from Surat Thani to Koh Samui as far in advance as you can. That’s not only because they’re usually in high demand, especially from November onwards, but also because doing that through a service like 12Go makes it easy to add on city-to-port transfers and taxis to your hotel after arrival.

Surat Thani to Koh Samui by normal ferry

Time – around 4 hours total
Price – $7-12
Comfort – 3/5

If you’ve got a little extra time to spare and don’t want to dip any deeper into the travel budget than you need to, the normal ferry could be the perfect way to get between Surat Thani and Koh Samui this year. It’s the slowest boat of all, yes, but it’s also the cheapest. Expect boat-only tickets to come in at around the $7 mark. Meanwhile, packages that include a transfer to the pier cost around $12. That should leave plenty for the PADI dives and Muay Thai sessions, don’t you think?

Normal ferries take you from Donsak Pier on the mainland to one of two piers on the west coast of Koh Samui.

Journeys typically start with a pickup in Surat Thani town or at the airport. Then you make the drive east along the shores of the mainland, between lines of coconut palms and mangrove, all the way Donsak Pier. Finally, it’s a short wait there before hopping onto the boat for the crossing over to ether Lipa Noi or Nathon on Samui. That all adds up to total travel times in the region of four to five hours. Just be aware that you’ll be arriving on the closer west coast of the island, so it might be worth bagging a ticket that includes an onward taxi to your hotel – most of which are on the east and north shores.
