Flights arrive and depart from all the major cities of India like Mumbai, Delhi, Pune, Chennai to Chiang Rai's International airport. The best airlines are Thai Airways, Bangkok Airways, AirAsia.
Chiang Rai's Mae Fah Luang Airport is located 10 km north of the city centre and operates both, international and domestic flights. This makes air travel a convenient way of reaching Chiang Rai.
Chiang Rai has well-connected roadways from Bangkok and Chiang Mai. However, the route from Bangkok to Chiang Rai is almost 800 km and can get uncomfortable if you plan to cover it without any other stops.
To reach Chiang Rai by train, you need to get to the nearby city of Chiang Mai by train, and then take the Green Bus to Chiang Rai. Chiang Mai is approximately 200 km away from Chiang Rai, and the Green Bus will take approximately 3 to 3 and a half hours to cover this distance.
There are two bus stations - Old Bus station (Terminal 1) and New Bus station (Terminal 2) here. The Old bus station is the main one where most of the bus services arrive and depart. Green bus services to and from Chiang Mai arrive and depart from both these bus stations.
The main modes of public transport in Chiang Rai are tuk-tuks, songthaews, and taxis. Exploring on foot is also a good option, but travellers prefer a vehicle due to time restrictions. If you don't want to travel by public transport, you can choose to rent a car or a motorbike; neither will cost too much. A couple of places to rent bikes from are ST Motorcycles and Chiang Rai Big Bike Rentals.
