From Bangkok, there are both air-conditioned and non-air-conditioned bus services from Bangkok's Northern Bus Terminal (Mo Chit 2) on Kamphaengphet 2 Road. The journey may take from 9 to 11 hours, though there are overnight sleeper busses available that may make the time seem to pass more quickly.

From Chiang Mai to Chiang Rai, air conditioned busses leave 12 times daily from Chiang Mai Arcade Bus Terminal for the three hour, 182 kilometer ride. Some busses continue on to Mae Sai and Chiang Saen.
