Long-distance buses reach almost every town in Thailand, including many places the railway never touches. The safest and simplest choice is a bus run by, or licensed through, the state company Transport Co. (BKS), boarded at one of Bangkok's three official bus terminals rather than a cheap "tourist bus" sold on Khao San Road.
Thailand's bus network is large. In May 2026 BKS said it carried 80,000 to 90,000 passengers a day on 5,000 to 6,000 trips, using its own fleet of 311 buses and more than 6,000 buses and vans run by licensed private partners. Fares are low, overnight services save a hotel night, and on routes such as Bangkok to the Andaman coast the bus is often the only ground option.
For comparing operators and booking several legs at once, see our article on 12Go.asia. This page explains how the system itself works: who runs the buses, where they leave from, what the classes mean and how to travel safely.

Who runs Thailand's buses
Transport Co., Ltd. is a state enterprise under the Ministry of Transport. It runs its own buses and also licenses private companies to run routes in its name; these are called "partner" (ruam) services, and they board at the same terminals and sell tickets at the same counters. When BKS issues a notice about delays or suspended routes, it covers both its own buses and the partners.
Private companies also run their own long-distance and regional networks. In the north, for example, Greenbus sells tickets online for routes around Chiang Mai, and Prempracha Transport runs the Chiang Mai to Pai and Mae Hong Son routes. Prempracha warns that times in its older published material are not current and must be checked in its booking system.
BKS cut its fares by 3 satang per kilometer per seat from 29 April 2026. That is a small change, but it shows that fares are set per kilometer and are publicly regulated rather than left to each seller.
Bangkok's three bus terminals
Almost every government and licensed bus out of Bangkok leaves from one of three terminals. Buying a ticket at the right one is the most important step.
| Terminal | Also called | Main direction | Getting there |
|---|---|---|---|
| Bangkok Bus Terminal (Chatuchak) | Mo Chit 2, Mo Chit Mai | Mainly north and northeast; some southern services start here | Near Krung Thep Aphiwat station and Chatuchak; taxi or bus from BTS Mo Chit |
| Borommaratchachonnani Bus Terminal | Southern Terminal, Sai Tai Mai | South and west | West bank of the river, Taling Chan area; taxi or Grab |
| Eastern Bus Terminal | Ekkamai | East: for example Chanthaburi and Laem Ngop, the pier for Koh Chang | Next to BTS Ekkamai on Sukhumvit |
Mo Chit 2 is the largest. It is close to Krung Thep Aphiwat Central Terminal, the station for long-distance trains, so it is easy to compare bus and train for the same trip. BKS also runs a small-vehicle station for vans and minibuses beside it, under the expressway; see our guide to minivans in Thailand.
The Southern Terminal is the least convenient for visitors because no rail line stops at its door. Allow plenty of time to get there in traffic. Some long southern routes, such as BKS's VIP service to Takua Pa and the Thap Lamu pier, start at Mo Chit 2 and call at the Southern Terminal on the way.
Ekkamai is the easiest to reach, right by the BTS. BKS notices list its routes to Chanthaburi and to Laem Ngop, the pier for Koh Chang; for the coast nearer Bangkok, our article on getting to Pattaya compares the options. Some east coast and Hua Hin coaches also leave straight from Suvarnabhumi Airport; our guide to Suvarnabhumi into Bangkok lists the boarding gates.
Bus classes: VIP, first and second class
Thai long-distance buses are graded by comfort, and the grade decides both the fare and the number of seats. At the top are VIP coaches with fewer, wider seats: BKS's Bangkok to Takua Pa and Thap Lamu service, launched in September 2026, uses a first-class VIP coach with 24 seats, travels 797 km and costs 1,075 baht (September 2026). Below that, standard air-conditioned first-class and second-class buses have more seats in each row, fewer extras and more stops.
Operators use their own names on top of these grades, such as "Super VIP" or "Gold", and what is included varies: a blanket, a snack and water, a toilet on board, sometimes a seat-back screen. Check the class and the number of seats on the ticket or booking page rather than relying on the name.
On overnight trips, the VIP seat is worth the difference. Fewer seats per row means a seat that reclines further and more room for your legs, which decides whether you sleep. On a daytime trip of three or four hours, a standard air-conditioned bus is fine.
Booking a ticket
For BKS and its partner routes there are four ways to book: the BKS website (tcl99web.transport.co.th), the BKS E-Ticket app, the booking line on 02-936-2841 to 48, and the ticket counters at every terminal. BKS also takes bookings through its LINE account (@BKS99). On most routes, buying at the terminal on the day works outside holidays.
Book ahead for overnight buses, for Friday and Sunday evenings, and for the big holiday periods, when demand is far higher than usual. In the days around Songkran and New Year, BKS adds extra buses, but popular departures still sell out. Our guide to Thai public holidays lists the dates to watch.
Private operators sell on their own websites, at their own counters inside the terminals and through agents and booking platforms. Whichever way you book, the ticket shows a seat number, a platform or bay, and a departure time; arrive 30 minutes early at a big terminal like Mo Chit 2.
Why to avoid the cheap Khao San tourist buses
Travel agents around Khao San Road and other backpacker areas sell cheap through tickets to Chiang Mai, the islands and the south, often including a pick-up. Many are fine. The problem is that you often do not know which company actually runs the bus, it may not be a licensed BKS partner, and travelers have reported thefts from bags stored in the luggage hold or under the seats on night trips for many years.
The UK Foreign Office warns travelers to avoid sleeping on buses and trains because "people have had items taken from bags while asleep". On any bus, cheap or not:
- keep your passport, cards, cash, phone and medicine in a small bag you hold or wear, not in the hold or the rack;
- lock the zips of the bag that goes in the hold, and take a photo of it;
- be wary if someone wants to "help" with your hand luggage or travels in the luggage area.
A bus that starts from a public terminal is the safer bet. A government or licensed partner bus, bought at Mo Chit 2, Ekkamai or the Southern Terminal, has a named operator you can complain to. A minibus collecting passengers from guesthouses at night is much harder to trace if something goes missing.
Road safety on long-distance buses
Buses are safer than minivans or riding a scooter, but road travel in Thailand carries a higher accident risk than many visitors are used to. BKS says it checks tyres, wipers, lights, brakes and seat belts before every trip, puts two drivers on routes longer than six hours, monitors its own buses by GPS, and asks passengers to keep their seat belts fastened. Do so, even if other passengers do not.
The front seats of a double-decker give a view, but on mountain roads the upper deck can feel the bends more. If you are prone to travel sickness, choose a lower-deck seat toward the middle. In the rainy season, watch for service notices: during the floods of late September 2026, BKS reported that licensed partners had suspended some routes in the east and asked passengers to allow extra time.
Bus, train or plane?
On the main lines north, northeast and south, the train is often more comfortable overnight because you can lie flat; see our guide to Thailand's night trains and the older comparison for Bangkok to Chiang Mai. The bus wins where there is no railway, such as most of the Andaman coast and the east coast. Planes are worth checking on long routes, since low-cost fares can be close to a VIP bus fare; see our guide to domestic flights.
Frequently asked questions
Which Bangkok bus terminal do I need?
Mo Chit 2 (Chatuchak) serves the north and northeast, the Southern Terminal (Borommaratchachonnani, or Sai Tai Mai) serves the south and west, and Ekkamai serves the east, including the Laem Ngop pier for Koh Chang. Some southern routes start at Mo Chit 2 and stop at the Southern Terminal.
How do I book a government bus in Thailand?
Transport Co. (BKS) sells tickets on its website tcl99web.transport.co.th, in the BKS E-Ticket app, through its booking line 02-936-2841 to 48 and at terminal counters. Outside holidays, you can usually buy at the terminal on the day.
Is the VIP bus worth it in Thailand?
For overnight or long trips, usually yes. VIP coaches have fewer seats per row, so seats are wider and recline further. On BKS's new route to Takua Pa and Thap Lamu, for example, the VIP coach has only 24 seats.
Are buses from Khao San Road safe?
Many run without problems, but travelers have long reported thefts from bags on these cheap night services, and the operator is often unclear. Keep valuables on your body, or buy a ticket for a licensed bus at a public terminal instead.
