Chiang Rai by Bus: Trams, Shuttles, Coaches
Chiang Rai has no railway station, and none is coming. The city’s rail line ends in Chiang Mai, so every bus in this guide is doing work a train would otherwise handle elsewhere in Thailand.
Getting to Chiang Rai: Green Bus
The Green Bus Regional Express is the standard way to reach Chiang Rai from Chiang Mai, running Highway 118 in about 3.5 hours with departures every 30 to 60 minutes. VIP and Class A tickets run roughly 180 to 320 THB, cheaper and, for most travelers, less hassle than driving the same route yourself.
Getting around once you land: the City Bus
Purple, air-conditioned Chiang Rai City Buses connect Mae Fah Luang Airport (CEI) with downtown, the Night Bazaar and Clock Tower area, and both bus terminals for a flat fare of 20 to 30 THB. It is the cheapest transfer from the airport by a wide margin over a taxi.
Seeing the old town: the Municipal Tram
An open sided electric tram departs from the King Mengrai the Great Monument on morning and afternoon runs, looping through the historic center with stops at Wat Phra Sing, Wat Phra Kaew, the Hill Tribe Museum, the OTOP craft center, and the Old Clock Tower. Commentary runs in Thai and English, and the fare is nominal, somewhere between free and 50 THB depending on the run.
Day coach tours to the Golden Triangle
Full-day, air-conditioned minibuses seating 12 to 15 link Chiang Rai with the White Temple, the Blue Temple, the Black House, the Golden Triangle viewpoint at Sop Ruak, and the border town of Mae Sai, with hotel pickup, an English-speaking guide, and lunch included for roughly $35 to $50 per person. This is the option that covers the most ground in a single day without renting a vehicle.
Verdict: if you are staying more than a day, the Municipal Tram plus a day coach tour covers the essential sights without ever needing your own transport, and the City Bus is really just an airport formality by comparison. For what those coach tours actually stop at, see the sightseeing guide .
