Part of: Paying in Thailand
Bangkok’s trains are several systems run by different companies, each with its own way to pay at the gate. The BTS Skytrain runs the Sukhumvit line in light green, the Silom line in dark green, and the short Gold Line people mover to Iconsiam. The MRT runs the Blue Line, the underground loop opened in 2004, and the Purple Line. The Yellow and Pink monorails, the SRT Red Lines out of Krung Thep Aphiwat and the airport line are separate again. For a visitor the spine is the two BTS lines and the MRT Blue loop, which meet at three interchanges: Asok and Sukhumvit, Sala Daeng and Si Lom, and Mo Chit and Chatuchak Park. Learn those three and most of the city is one change away.
The trains cover the distance. The rest is a boat, a ride app or a motorbike taxi, depending on where the line runs out.
How the city moves
Ride the BTS on a Rabbit card
As of October 2026 the BTS Skytrain doesn't take contactless bank cards at the gate. It runs on the Rabbit card, sold at BTS ticket offices, and on single-journey cards from the ticket machines; there's a one-day pass too. Newer touchscreen machines take notes; older ones take coins only, so keep some. The plain Rabbit card is the one you want, and it also works on the Yellow and Pink monorails. It doesn't work on the MRT.
Tap a credit card on the MRT
The MRT Blue and Purple lines take contactless bank cards, and many gates take nothing else; the old MRT stored-value cards stopped working on June 1, 2026. The catch is the card. The operator accepts credit cards from any Thai or foreign bank but debit cards only from certain Thai banks, so a foreign debit card can bounce at the gate. Bring a contactless credit card, tap in and out with the same one, and carry a spare. The airport line and the SRT Red Lines take the same tap. On the Yellow monorail, some stations read bank cards only at a separate reader beside the wide gate.
Buy a new ticket when you change systems
There's no through fare between the systems yet: going from the MRT to the BTS means tapping out with your bank card, then tapping a Rabbit card or buying a BTS ticket. A common ticket across the lines is planned for January 1, 2027, on the contactless standard, which could let one card work across the lines. But the BTS says new gate readers take about 18 months to install, and a stopgap for January is still being worked out. Don't plan on a single tap across the network yet.
Read the river boats by their flags
The Chao Phraya Express marks its lines by the flag on the boat: orange for the everyday local line, yellow and green-yellow for the commuter expresses, red for air-conditioned, no flag for the local stopper. The blue-flag tourist boat hops on and off from Phra Arthit toward Asiatic. The hub is Sathorn pier under Taksin Bridge, beside BTS Saphan Taksin. Get off at Tha Tien for Wat Pho, at Tha Chang for the Grand Palace, at Phra Arthit for Banglamphu. Since April 2024 the orange boats stop at Tha Tien instead of Wat Arun, so cross to the temple on the small ferry from Tha Tien.
Cross the middle on the canal boat
The Khlong Saen Saep boat is the fast, wet way locals cross the center: a long, low boat with plastic spray screens along its sides. It runs two lines that meet at Pratunam, where everyone changes boats. The useful piers are Panfa Leelard at the Old Town end, Saphan Hua Chang near Siam and Ratchathewi, and Asok-Phetchaburi near MRT Phetchaburi. A conductor collects the fare on board, in cash, so have small notes ready.
Ride apps, taxis and the motorbike rank
Grab and Bolt both run cars and motorbikes, with the price upfront; it rises in rain and rush hour. Bangkok's taxis are metered, and drivers refusing the meter is a long-standing complaint, so say 'meter, please' before you sit down and get out if you're quoted a flat price. For the last stretch, use the motorbike taxi rank at the mouth of most sois: licensed riders wear numbered orange vests, short hops are priced by the rank or agreed first, and many riders carry a spare helmet. Ask for it and wear it.
Bangkok is walkable in pockets and hostile between them. Ari’s sois, the Old Town, Talat Noi and Chinatown at night are good on foot; the gaps are heat, broken sidewalks and footbridges over arterial roads. Use the elevated walkways, and look right first, since Thailand drives on the left. Traffic is the real danger, and bag snatchers on motorbikes are the reason to keep your phone on the side away from the road.
Trains and roads both peak in the early morning and from late afternoon into the evening, and in the rainy season the afternoon storms flood sois and underpasses fast, which is when the ride apps surge. The city buses are a huge network, renumbered in 2024 and moving to electric; the ViaBus app tracks them and the boats, but they’re not a first-week tool.

The gates and ride apps above don’t use the counter QR; that code belongs to shops and cafés. For those, verify in the Yodl app before your first payment, then scan the PromptPay or Thai QR at the counter, and a licensed local partner pays the merchant in baht. Carry small notes for the canal boat, which takes cash on board, and for the motorbike rank and the tuk-tuk. Everything else about paying is in the Thailand payment guide.
Mistakes to avoid
Tapping a bank card at a BTS gate
The Skytrain doesn't take bank cards yet. Buy a Rabbit card at the ticket office on your first ride, or a single ticket from the machine, and keep some coins for the older machines.
Counting on a foreign debit card at the MRT
The MRT takes foreign credit cards, but debit cards only from certain Thai banks. Use a contactless credit card and carry a second card in case the first is refused.
Riding a motorbike taxi without the helmet
Many riders carry a spare; ask for it and wear it. Motorbike crash rates are high, and traffic is the main danger in the city.
Saying yes to a detour
A stranger who says the palace is closed and a tuk-tuk driver who knows a better temple are the same pitch. Check the official notice, agree the fare first, and decline every stop you didn't ask for.
Common questions
What's the best way to get around Bangkok?
Take the BTS Skytrain and the MRT for anything more than a neighborhood away, a motorbike taxi or Grab for the last stretch down a long soi, and the river boats for the Old Town, which has no BTS. Walk inside a neighborhood, not between them. After dark or in a storm, a ride app door to door.
Can I tap my contactless card on the BTS?
Not as of October 2026. The BTS Skytrain, Silom and Gold lines included, runs on its own Rabbit card and single-journey tickets; buy the plain Rabbit card at a ticket office if you'll ride more than once or twice. The MRT, the airport line and the SRT Red Lines take contactless bank cards at the gate.
Will my foreign debit card work at the MRT?
It might not. The MRT's operator takes credit cards from any Thai or foreign bank but debit cards only from certain Thai banks, so a foreign debit card can be refused. Bring a contactless credit card and a backup. A small pending hold after a credit-card tap is normal.
Are tuk-tuks a scam?
Not in themselves. They're unmetered, so agree the price before you get in, and take one for the ride itself rather than to cross town. The scam is the detour: a friendly stranger near the Grand Palace says it's closed today and steers you to a waiting tuk-tuk, another temple and then a gem or tailor shop. Check the official notice, not a stranger, and decline any stop you didn't ask for.
