CNX Airport Car Rental — Chiang Mai International Airport

Chiang Mai International Airport (CNX) is Northern Thailand's most important airport and offers as many as 15 rental companies on-site – one of Thailand's best selections outside Bangkok. The airport is 4 km southwest of the city center, just 10 minutes' drive. Rent a car right upon arrival and start exploring mountains and cultural landscape immediately.

From CNX, you can reach Chiang Mai's Old City in 10 minutes via Mahidol Road. Doi Suthep Temple, located 15 km northwest of the airport, is reached in 30 minutes and offers fantastic views. Chiang Rai is 180 km to the north via Highway 1 and takes about 3 hours.

With 15 rental companies at CNX, you can compare prices directly in the arrivals lounge – but advance booking often gives better prices. Choose a car with automatic transmission if you'll be driving mountain roads like Route 1095 to Pai. Check your insurance carefully – mountain roads can be challenging during the rainy season (June–October).
