From the misty hills of Chiang Mai to the temples of Angkor, this trip takes you from the Lanna north of Thailand to the Khmer heartland of Cambodia. The sunrise over Angkor Wat makes the journey worth it.
Fly. The land crossings between Thailand and Cambodia are suspended, so the route by air via Bangkok is the way to go.
Chiang Mai to Siem Reap by Plane
Thai AirAsia flies from Chiang Mai (CNX) via Bangkok Don Mueang (DMK) to Siem Reap-Angkor International Airport (SAI). Fares start at THB 4,090 one way, and the total trip takes from about 5 hours 30 minutes with a short layover to 10 hours with a long one.[1]
Thai Airways and Thai Vietjet also connect through Bangkok Suvarnabhumi (BKK), at THB 6,964 to 7,801 on sample dates. These are separate tickets with a self-transfer, so leave a long layover.[1]
The second leg, Bangkok to Siem Reap, is a non-stop flight of about 1 hour 5 minutes.[2]
Why Not Overland
Land borders and crossings between Thailand and Cambodia are suspended, and the UK Foreign Office advises against all but essential travel within 20 km of the border.[3]
Poipet is also closed for e-visa entry until further notice.[4]
Entry Rules for Cambodia
You need a visa. The e-visa costs USD 30 (Visa T) or USD 35 (Visa E), allows one entry within 3 months and a stay of 1 month, and takes 3 business days to process. Siem Reap-Angkor airport accepts it.[4]
Fill in the Cambodia e-Arrival form within 7 days before you arrive.[4]
