Getting Around Thailand: Complete Transport Guide 2026
Thailand has one of Southeast Asia's most comprehensive transport networks — from a world-class Bangkok metro to overnight trains through the jungle. Here's how to navigate it all efficiently and cheaply.
Verified: October 28, 2026
Major International Airports
BKK — Suvarnabhumi
- Bangkok
Thailand's main international hub. Handles 60+ million passengers/year. Connected to central Bangkok via Airport Rail Link (30 min, 45 THB) and taxis (350–550 THB to Sukhumvit, +50 THB airport surcharge + tolls).
DMK — Don Mueang
- Bangkok (North)
Bangkok's second airport, mainly for low-cost airlines (Thai AirAsia, Nok Air, Thai Lion Air). The SRT Red Line runs from Don Mueang station, next to the airport, to Krung Thep Aphiwat Central Terminal (20 THB when checked). Other options: a metered taxi (400–600 THB to the centre) or the A1 bus to Mo Chit BTS (30 THB).
HKT — Phuket International
- Phuket
Gateway to Thailand's most famous beaches. No rail link — use metered taxi (600–900 THB to Patong), airport bus (100 THB), or Grab. Journey to Patong takes 45–60 min depending on traffic.
CNX — Chiang Mai International
- Chiang Mai
Northern Thailand's main airport. Just 10 minutes from the old city by taxi (120–160 THB). Red Songthaew minivans are 40–60 THB. Grab works well here.
USM — Koh Samui
- Koh Samui
Privately owned airport (Bangkok Airways). More expensive flights but ultra-convenient. Taxis to Chaweng Beach 300–400 THB.
Domestic Flights
For distances over 500 km, flying is almost always faster and often cheaper than other options. Bangkok to Chiang Mai is 1 hour by air vs 10+ hours by train.

Book via 12Go.asia, Google Flights, or the airline's own app. Book 4–8 weeks ahead for best prices. Sales occasionally offer BKK–CNX for under 500 THB one-way.
Long-Distance Trains
The State Railway of Thailand operates routes from Bangkok's Hua Lamphong and Bang Sue (Krung Thep Aphiwat) stations. Trains are cheap, scenic, and a genuinely enjoyable travel experience — but not always on time.
Bangkok → Chiang Mai
13–15 hours (overnight)2nd class sleeper: 520–1,100 THB
Book online on the SRT D-Ticket website (dticket.railway.co.th). Fan vs A/C sleeper available.
Bangkok → Surat Thani (Koh Samui/Phangan)
10–12 hours (overnight)2nd class sleeper: 450–900 THB
Combine with ferry at Surat Thani for island travel.
Bangkok → Ayutthaya
1.5 hours3rd class: 20 THB
Perfect day trip from Bangkok. Multiple departures daily.
Bangkok → Kanchanaburi
3 hours3rd class: 100 THB
Includes the famous Bridge on the River Kwai route.
Long-Distance Buses
Thailand's bus network covers destinations not served by rail. The main hub is Bangkok's Mo Chit (Northern Terminal) and Ekkamai (Eastern Terminal).
| Class | Features | Price Range |
|---|---|---|
| VIP / Gold | Reclining seats, A/C, toilet, snacks included, fewer stops | 600–1,200 THB |
| 1st Class | A/C, reclining seats, on-board toilet | 350–700 THB |
| 2nd Class | A/C, standard seats | 150–400 THB |
| Minivan | Faster, door-to-door, but cramped | 100–300 THB |
Bangkok City Transport
BTS Skytrain
- Highly recommended
Elevated rapid transit covering Sukhumvit, Silom, and Siam. Fast, A/C, clean. Fares depend on distance. Runs from about 06:00 to midnight.
MRT Subway
- Highly recommended
Underground metro covering Bangkok's older districts and connecting to BTS interchange stations. Similar fare structure to BTS. Extended hours in some sections.
Grab
- Best for most journeys
Southeast Asia's Uber equivalent. Fixed prices, clean cars, A/C. Much better than negotiating with taxis. Essential app for Thailand travel.
Metered Taxis
- Good option
Meter starts at 35 THB. Always insist on the meter — say 'meter na krap/ka'. Avoid taxis near tourist spots that quote flat rates. Colors: red-yellow, green-yellow, blue.
Tuk-Tuks
- Tourist experience only
Iconic three-wheeled vehicles. Fun for photos but negotiated flat fares are usually 2–3x taxi prices. Beware of tuk-tuk drivers offering 'tours' or taking you to gem shops — it's a scam.
Chao Phraya Express Boat
- Great for sightseeing
Scenic river boats connecting riverside temples and neighbourhoods. Orange flag: the standard line, 19 THB flat fare. Yellow and green-yellow flags: express lines, 24 THB flat. Red flag: 33 THB. Fares as checked on 28 October 2026. Separate tourist boats also run on the river.
Islands & Southern Transport
Phuket Island
Metered taxis are rare in Phuket, and most taxis charge fixed fares. Use Grab where available, or agree the fare before you get in. Songthaew shared vans run fixed routes between Phuket Town and beaches (50–100 THB). Smart Bus covers main beach routes.
Motorbike Rental
Available everywhere from 150–300 THB/day. You legally need an International Driving Permit (IDP) or Thai license to ride. Police checkpoints in tourist areas regularly fine unlicensed riders 500–1,000 THB. Helmet laws are enforced — wear one, fatality rates are high.
Ferry Routes to Islands
Surat Thani → Koh Samui
1.5 hrs · 200–500 THB
Surat Thani → Koh Phangan
2.5 hrs · 250–600 THB
Surat Thani → Koh Tao

Choosing between plane, train and bus on the routes people actually take
The comparison that matters is not "which is cheapest" but what each option costs you in a day.
| Bangkok to Chiang Mai | Time | Cost | Worth it when |
|---|---|---|---|
| Flight | 1h 15m plus airport time | Often 900 to 2,500 baht | Almost always |
| Overnight train | 13 to 15 hours | 520 to 1,100 baht sleeper | You want the journey, and it saves a hotel night |
| VIP bus | 10 to 12 hours | 600 to 1,200 baht | Rarely — the train is more comfortable for similar money |
| Bangkok to Koh Samui | Time | Cost | Worth it when |
|---|---|---|---|
| Direct flight | 1h 15m | Expensive; one airline owns the airport | Time matters more than money |
| Flight to Surat Thani, then ferry | 4 to 6 hours total | Much cheaper | Usually the sensible choice |
| Overnight train, then ferry | 14 to 16 hours | Cheapest | You enjoy trains and have the day |
| Bangkok to Phuket | Time | Cost | Worth it when |
|---|---|---|---|
| Flight | 1h 25m | Frequently cheap | Almost always |
| Bus | 12 hours plus | 800 to 1,400 baht | Only if flights are sold out |
The pattern: on long domestic routes, flying usually wins on price and time, because low-cost competition is fierce. The train earns its place on the Chiang Mai run specifically, where the sleeper replaces a hotel night and the scenery is the point.
The motorbike question, answered honestly
This is the most consequential decision in this guide, and most guides treat it as a pricing question.
The licence. To ride legally you need a motorcycle entitlement — an International Driving Permit that covers motorcycles, or a Thai licence. A car-only IDP does not cover a scooter. Rental shops hand over the keys regardless; that is not permission, it is a shop wanting 250 baht.
The insurance consequence. This is the part that matters. If you ride without the correct licence, your travel insurance will generally decline a medical claim from an accident. Thai hospitals require payment guarantees, and a serious motorbike injury runs into tens of thousands of dollars. The 250-baht rental becomes the most expensive decision of the trip.
The risk itself. Road traffic injuries are among the leading causes of death for visitors to Thailand, and scooters account for most of them. Gravel, sand on coastal roads, unfamiliar traffic patterns and rented helmets of unknown quality all stack against a rider who last rode a scooter on holiday a year ago.
If you ride anyway: wear the helmet, expect police checkpoints that specifically look for licences, photograph the bike from every angle before you leave the shop, and never hand over your passport as a deposit — pay a cash deposit instead.
The scams, and the shape they share
Nearly every transport scam in Thailand works the same way: an official-sounding person redirects you from the thing you asked for.
"The Grand Palace is closed today." It is not. The person telling you is working with a tuk-tuk driver who will take you to a gem shop or tailor instead. Walk to the entrance and check for yourself.
The tuk-tuk tour at an impossible price. A 20-baht all-day tour is subsidised by the shops you will be taken to and expected to buy from. It is not a bargain, it is an obligation.
"Meter broken." Find another taxi. There is no negotiation worth having; the next taxi's meter works.
Jet-ski damage claims. Pre-existing damage is discovered on your return and settled aggressively. Photograph everything before you take it out, or skip it.
The bus-station "official" ticket desk. At Bangkok's terminals, the government counters are inside; desks outside promising a better price are selling something else.
The defence is the same each time: go to the official queue, counter or entrance rather than the person who approached you.
Booking overnight trains without disappointment
Sleepers on the Chiang Mai and southern routes sell out, particularly in peak season and around festivals.
- Book two to four weeks ahead for a second-class air-conditioned sleeper, longer around Songkran and New Year.
- Lower berths cost more and are worth it — more space, a window, and you are not climbing down in the dark.
- Air-conditioned carriages are cold. Genuinely. Bring a layer; the blanket provided is thin.
- Departure stations changed. Many long-distance services now leave from Krung Thep Aphiwat (Bang Sue) rather than the old Hua Lamphong. Confirm which station your ticket names, and allow for the transfer across the city.
Ferries and the weather
Island transfers are the leg most likely to break a plan.
Ferry services reduce or stop in rough conditions, and the Gulf coast's worst weather is November and December — precisely when the Andaman coast is at its best. Services do resume, but a cancelled crossing costs you a day and, if a flight is on the other side of it, considerably more.
The practical rules: never plan a ferry on the same day as an international departure, book joint tickets through the operator so a missed connection is theirs to resolve rather than yours, and treat the published crossing time as optimistic in bad weather.
