Chiang Mai public transport: tickets, passes and apps

Chiang Mai has no single transport card that covers everything, and no day pass that pays for itself. The city runs on three parallel systems: red songthaews (shared pickups), a small city bus network, and ride-hailing apps. Each is paid for separately.

The practical answer is to pay per ride. Use songthaews for short hops inside the old city and along the moat, city buses for fixed routes such as the airport road and Arcade bus station, and Grab or Bolt when you want a door-to-door trip, air conditioning or a fixed price. A pass only makes sense if you plan several bus rides a day, which few visitors do.

Songthaews are cash only. You flag one down, tell the driver your destination, agree the fare before you get in, and pay on arrival. Short rides inside the old city are usually a flat rate per person; longer trips cost more. Have small notes and coins ready, because drivers rarely carry change for ฿500.

City buses take cash in a fare box or to a conductor, depending on the route. Ride-hailing is the easiest cash-free option: Grab and Bolt both accept cards in the app, show the price before you book, and remove the need to negotiate. PromptPay QR is widely used by Thai riders but needs a Thai bank account, so most visitors cannot use it.

No contactless bank card tap is accepted on songthaews or city buses. If you want to avoid cash entirely, plan your day around Grab and Bolt and keep a few hundred baht for the short songthaew hops.

Chiang Mai does not use fare zones in the way Bangkok's BTS does. Songthaew prices are agreed per trip and rise with distance: roughly ฿30 for a hop within the old city or along the moat, ฿40–60 to Nimman, the riverside or the night bazaar area, and more for outer districts such as Hang Dong or Mae Rim.

City bus routes are numbered and priced by route rather than by zone, with a flat or near-flat fare. Airport-bound buses and the routes linking the Arcade bus station to the centre are the ones visitors use most. Fares are low, but service is infrequent in the evening and on weekends, so check the last departure before you rely on it.

For a group of three or four, a Grab car often costs about the same as four songthaew seats and drops you at the door, which is worth knowing in the rain or after dark.

Chiang Mai International Airport (CNX) sits about 3 km southwest of the old city, so the transfer is short. The official taxi counter inside the arrivals hall sells a fixed-price trip to the city, roughly ฿150–200 depending on the district, which avoids any negotiation. Ride-hailing pickups work too, but the app car may cost similar or slightly more after the airport surcharge.

There is no airport train or metro. A city bus serves the airport road on some routes, but timings are unreliable with luggage, so most travellers take the taxi counter or an app. If you are staying near the airport, several hotels are within a 10-minute walk of the terminal, which removes the transfer entirely.

For onward travel, the Arcade bus station handles long-distance buses to Chiang Rai, Pai and Bangkok, and the train station covers the northern line. Both are a short songthaew or Grab ride from the old city.

Agree the songthaew fare before you get in, and expect to share the truck with other passengers going roughly the same way. Drivers sometimes wait until the truck fills, which can add ten minutes to a short trip.

Keep small notes. A ฿100 note for a ฿30 ride is a common source of friction, and drivers may not have change early in the day.

Traffic is the main variable in Chiang Mai, not distance. The moat ring road and the Nimman area slow to a crawl at rush hour, so a 3 km trip can take 25 minutes. Build that into airport and station transfers.

Scooter rental is popular but only legal with a motorcycle licence and an International Driving Permit; police checkpoints fine unlicensed riders and insurance will not pay out after a crash. If you want your own wheels without that risk, compare a rental car instead.

For a single day of temple-hopping, a hired driver or a day tour with hotel pickup often costs less than stringing together songthaews and Grab rides, especially for Doi Suthep and the outer temples.
