How to Get to Koh Tao: Ferry Options

← Home

Koh Tao has no airport, so getting there always means a ferry, either via Koh Samui or Koh Phangan, or directly from the mainland at Chumphon, and the boat itself is very much part of the trip rather than just a logistics step. Which route makes sense depends on where you’re starting from and whether diving or budget matters more than speed. This guide covers every realistic option.

From Koh Samui

Three operators run this route, with departures spread through the morning and early afternoon:

Operator	Travel Time	Price
Lomprayah	~1.5 hours	~350-450 THB
Seatran Discovery	~2 hours	~300-400 THB
Songserm Express	~2-2.5 hours	~250-350 THB

Departures typically start around 8am with the last sailing mid-afternoon, so this isn’t a route you can leave until evening. See our Koh Samui flight vs ferry guide if you’re flying in from Bangkok or abroad first.

From Koh Phangan

The shortest crossing on this list, roughly 45 minutes, run by the same Lomprayah and Seatran services that continue on to or from Koh Samui. If you’re island-hopping through the Gulf of Thailand, this is the natural next leg after Koh Phangan. See our Koh Phangan ferry guide for the first leg if you haven’t been there yet.

From Chumphon (Mainland)

Chumphon is the standard mainland gateway for travelers coming overland from Bangkok, either by overnight train or a shorter regional flight into Chumphon Airport, without routing through Koh Samui or Koh Phangan at all:

Operator	Travel Time	Price
Lomprayah (high-speed catamaran)	~2 hours	~600-700 THB
Songserm (speedboat)	~2.5 hours	~500-550 THB
Night boat (Midnight Express)	~6-8 hours	~300-450 THB

The Lomprayah morning departure is timed to meet travelers arriving on the overnight train from Bangkok, and the operator runs a shuttle bus from its town-center office to the pier as part of a combined train-plus-ferry booking, one of the more reliably smooth connections on this whole route. The night boat is the budget option, departing around 11pm and arriving by 5-6am, basic (foam mats or a simple cabin bunk) but genuinely popular with backpackers who’d rather sleep through the crossing than pay for a hotel night in Chumphon.

How to Get to Koh Tao: Which Option Should You Choose?

Coming from Koh Samui or Koh Phangan already: Lomprayah is generally the fastest and most reliable. Flying into Bangkok and heading straight for Koh Tao: the overnight train plus the morning Lomprayah departure from Chumphon is the standard, well-optimized route. On a tight budget: the Chumphon night boat saves real money at the cost of comfort and a night’s sleep in a bed. Diving as the main purpose of the trip: any of the daytime routes work fine, just build in the rest-day buffer described below.

Booking Tips

Book at least a day ahead in high season (December-April), when the earlier, more convenient departures sell out first. If you’re arriving specifically to start a dive course, check whether your dive shop offers a pier pickup, several do for enrolled students, which saves sorting out onward transport to your accommodation on arrival. See our where to stay in Koh Tao guide if you haven’t settled on an area yet.

A Note on Rough Crossings

Koh Tao’s ferry routes cross more open water than the short hops between Koh Samui and Koh Phangan, and the crossing can get genuinely choppy outside the calmest months, particularly on the Chumphon route and during the wetter stretch of the year (roughly September through mid-December, the same wet season the rest of the Gulf of Thailand islands share). If you’re prone to seasickness, take medication before boarding rather than after symptoms start, and consider the slower, larger Songserm boats over the faster catamarans on a rough day, they handle swell more comfortably even though the crossing takes longer.

Timing Your Ferry Around a Dive Course

If diving is the main reason for the trip, arrive with at least one full rest day before your first dive if you’ve flown internationally in the last 24 hours, most dive shops require this for safety reasons regardless of how you feel. Similarly, plan your departure ferry for at least 18-24 hours after your last dive, flying or even just the altitude change on some mainland routes too soon after diving carries a real decompression sickness risk. Building this buffer into your ferry booking on both ends avoids a last-minute scramble to push back a flight or ferry.

Bringing Your Own Dive Gear

If you’re traveling with your own dive equipment, standard checked baggage allowances usually cover a basic kit, but weigh it before you leave home, gear adds up fast. All the ferry operators covered here handle luggage normally, there’s no special dive-gear surcharge on the boat itself, though a full set of gear bags can be awkward on the smaller speedboats, worth mentioning to staff when boarding so they can stow it properly rather than leaving it loose on deck.

Combined Train and Ferry Tickets

Most ferry operators and third-party booking sites sell a combined overnight-train-plus-ferry ticket from Bangkok all the way through to Koh Tao, which is usually simpler and occasionally cheaper than booking the train and ferry separately. It also guarantees your ferry seat is held for the train’s actual arrival time rather than a fixed departure you might miss if the train runs late, worth the small extra cost for the peace of mind alone on a first visit.

Frequently Asked Questions

Does Koh Tao have an airport?

No, every visitor arrives by ferry, either via Koh Samui, Koh Phangan, or directly from Chumphon on the mainland.

What’s the fastest way to reach Koh Tao?

Flying into Koh Samui and taking the Lomprayah high-speed ferry, roughly 1.5 hours on the water.

Is the Chumphon night boat safe and comfortable?

It’s basic but generally reliable, foam mats or a simple cabin bunk rather than a proper bed. It’s popular specifically because it saves a hotel night, not for the comfort.

Can I get to Koh Tao directly from Bangkok?

Not directly by boat, you’ll always transit through Chumphon, Koh Samui, or Koh Phangan. The overnight train to Chumphon plus a morning ferry is the most common combination.

Do ferries to Koh Tao run every day?

Yes, year-round, though frequency drops somewhat outside high season. Book a day or two ahead regardless of season if your dates are fixed.
