How to Get from Bangkok to Koh Tao: A Local’s Guide (2026)

I’ve lived on Koh Tao for four years, and I’ve done the Bangkok–Koh Tao route more times than I can count. I’ve tried all the options (buses, ferries, flights, combinations of all three) and over time I’ve learned that there isn’t one “best” way to get to the island.

The best way to get from Bangkok to Koh Tao depends less on price and more on when you arrive in Bangkok and whether you want to move immediately or not.

• If you’re flying into Bangkok and want to continue straight to Koh Tao, flying down to Surat Thani or Koh Samui and taking a ferry is usually the easiest option — as long as you arrive early enough.
• If you arrive in Bangkok late afternoon or early evening, you won’t make it to the island the same day. In that case, the Lomprayah overnight bus + ferry combo makes the most sense. There’s a night bus that leaves around 9 PM, so you travel overnight and arrive on Koh Tao in the morning.
• If you’re already staying in Bangkok and heading south later, the Lomprayah combo is usually the simplest and least stressful choice.

I’d much rather spend an extra night in Bangkok than get stuck in Surat Thani after missing a ferry.

This guide breaks down the routes I actually use and recommend, who each option is best for, and which ones I’d personally avoid. If you’re heading to Koh Tao for the first time or you did this journey once and didn’t enjoy it, this should help you choose the route that makes the most sense for your trip.

Lomprayah bus + ferry combo (the easiest all-round option)

If you want the simplest and least stressful way to travel from Bangkok to Koh Tao, the Lomprayah bus + ferry combo is the option I recommend most often, especially for first-time visitors.

It’s a single ticket that covers the entire journey: bus out of Bangkok, transfer to the pier, and ferry to Koh Tao. You don’t have to coordinate schedules yourself, worry about missing connections, or deal with multiple operators along the way.

I’ve done this route many times while living on Koh Tao, most recently in December 2025, using the VIP bus upgrade, and it’s still the option I default to when I want a smooth, predictable trip.

When the Lomprayah combo makes the most sense

This route is ideal if:

• You’re already staying in Bangkok and heading south later
• You arrive in Bangkok late afternoon or early evening
• You don’t want to risk missing a ferry on the same day
• You’d rather travel overnight and arrive on Koh Tao in the morning

There’s a night bus leaving Bangkok at around 9 PM, which makes this especially practical. You sleep on the bus, transfer to the ferry in the morning, and arrive on Koh Tao ready to start your day.

What to expect

• One booking, one operator
• Overnight travel option available
• Straightforward transfers
• No airports, taxis, or tight timelines to manage

It’s not the fastest option on paper, but it’s one of the most reliable, which matters a lot on this route.

The Lomprayah VIP Bus Upgrade

I always book the VIP bus upgrade with Lomprayah when it’s available. It’s not luxury by any means, but it does make a noticeable difference on an overnight journey.

The seats are wider, there’s more legroom, and there are fewer seats, which makes it generally quieter than the standard bus. I find it much easier to actually sleep, which makes the morning ferry a lot more bearable. After doing this route so many times, that extra bit of comfort is worth it for me.

If you’re taking the overnight bus, I’d recommend upgrading if you can. If you’re on a tighter budget, the regular bus is fine, but the VIP option makes the whole trip feel less draining.

Cost of the combo ticket

The Lomprayah bus + ferry combo currently costs 1,250 THB (~€32 / ~$35) for the regular bus, or 1,550 THB (~€40 / ~$43) if you upgrade to the VIP bus.

Downsides (worth knowing)

The bus ride isn’t luxurious, even with the VIP upgrade, and it’s a long journey. If you’re landing in Bangkok early in the day and want to continue immediately, flying south can save time.

That said, for ease and peace of mind, this route is hard to beat.

If you want to double-check departure times, you can also view the current Lomprayah timetable directly on their website.

Flying south + ferry (best if you want to keep moving)

If you’re flying into Bangkok and want to continue to Koh Tao without staying overnight in the city, flying south and taking a ferry can be a good option, as long as your timing works.

This route makes the most sense when you arrive in Bangkok early enough in the day to comfortably catch a domestic flight and still make a ferry connection. I’ve done this route plenty of times, and when it works, it’s a smooth way to reach the island the same day.

You’ve got two realistic airport options.

Flying to Surat Thani (my default)

Flying to Surat Thani is usually the most practical choice. Flights are frequent, prices are reasonable, and ferry connections are well set up.

What I usually do is book a transfer + ferry combo ticket with Lomprayah straight from Surat Thani Airport. A van picks you up at the airport, takes you to the pier (usually Donsak), and you continue by ferry to Koh Tao. You don’t need to organize taxis or worry about finding the right pier yourself.

This option works well because:

• Flights are generally cheaper than Koh Samui
• There are more airline options
• Transfers are straightforward if booked as a combo

Cost (rough guide):

• Flights from Bangkok: 800–2,000 THB (€21–€52 / $23–$56)
• Transfer + ferry to Koh Tao: 700–900 THB (€18–€23 / $20–$25)

If you arrive early in Bangkok and want to keep moving, this is usually the option I recommend.

From experience: When timing allows, this is my go-to flight route. Booking the transfer and ferry together takes a lot of stress out of the day.

Flying to Koh Samui (convenient in specific cases)

Flying to Koh Samui sounds appealing, but in practice, it’s not much faster overall. The speedboat to Koh Tao takes about as long as coming from the mainland, and getting through Samui airport, plus the transfer to the pier, adds time.

Flights are also significantly more expensive, since Samui is a privately owned airport and flights are operated by Bangkok Airways only.

That said, Samui does make sense in certain situations.

I’d actually recommend Samui when you’re arriving on a long-haul international flight. Bangkok Airways has partnerships with many airlines like Qatar Airways, which often allows your luggage to be checked all the way through to Koh Samui.

Not having to collect bags in Bangkok, recheck them, and deal with domestic baggage rules can make the Samui route feel much easier, even if it’s more expensive and not technically faster overall.

Just like in Surat Thani, you can book a van + ferry combo from Samui Airport, so once you land, the logistics are straightforward.

Flying via Samui can make sense if:

• You’re arriving on a long-haul international flight and want your luggage checked through
• You’re traveling with a lot of luggage
• Price isn’t a major concern
• You want the simplest airport experience possible

Cost (rough guide):

• Flights from Bangkok: 3,000–6,000+ THB (€78–€155 / $85–$170)
• Transfer + ferry to Koh Tao: 600–800 THB (€16–€21 / $18–$23)

From experience: After a long-haul flight, that extra convenience can be worth it. Outside of that situation, I usually prefer flying to Surat Thani instead.

Timing matters more than the route

If you arrive in Bangkok late afternoon or early evening, flying south usually doesn’t work. You’ll miss the last ferry connections and risk getting stuck overnight near Surat Thani or Samui.

That’s exactly when the overnight Lomprayah bus + ferry combo becomes the better option.

Who this route is best for

Flying south and taking a ferry works best if:

• You land in Bangkok early in the day
• You want to reach Koh Tao as soon as possible
• You’re comfortable with multiple steps
• You’re happy to pay more for speed or convenience

At a Glance: Which Route Is Right for You?

Route Check by Arrival Time

Since ferries don’t run around the clock, your arrival time in Bangkok determines which route is actually doable for you. Here is my quick overview for your planning:

Routes I usually skip

Not every route from Bangkok to Koh Tao is worth the effort. These are the ones I personally avoid most of the time, unless there’s a very specific reason to take them.

Trains + ferry

I generally don’t recommend taking the train. On paper, it sounds comfortable, but in reality it’s unreliable and slow. Delays happen often, and if you miss a ferry connection, you can easily lose a full day.

If you’ve got loads of time, enjoy train travel, and don’t mind plans changing last minute, it can be an experience. Otherwise, the bus or flying south is simply easier and more predictable.

From experience: The last time I took the train south from Bangkok, we arrived with a four-hour delay. I missed my ferry connection and ended up having to stay overnight in Surat Thani, even though everything looked fine when I planned it.

Flying to Chumphon

Flying to Chumphon does work, but I don’t usually recommend it as a first choice. Flights are limited, timing can be awkward, and if something changes, there are fewer backup options compared to Surat Thani.

If it lines up perfectly with your schedule, it’s fine. But most of the time, Surat Thani offers more flexibility and fewer headaches.

Mixing too many separate tickets

Booking flights, buses, transfers, and ferries all separately might look cheaper at first, but it’s often where things go wrong. One delay can break the whole chain.

That’s why I usually stick to combo tickets (bus + ferry, or transfer + ferry) whenever possible. Fewer moving parts mean less stress.
