North and North Eastern bus terminal for bangkok is generally called Morchit 2. But not only buses to north and north eastern region,it also has buses to central and eastern region.
Located just next to the expressway, so the terminal can be easily reached by taxis from any corners of Bangkok.
When first visit to Morchit 2, you might stunt with so many ticket windows.
There are several bus company offering their service under the licenses from Transport Company, the government-owned bus company. In some route like Chiangmai which is the poppular destination, there are a dozen company compete in this route.
So don’t surprise to see many windows sell ticket for Chiangmai.
Anyway, all on the front wall outside the terminal are Northern routes windows.
Ticket windows for eastern buses are along the wall after you get into the terminal.
The orange letters on the windows mean they sell ticket for 2nd class buses.
These kind of buses take more time to get to the destination because they stop (or may be park for 10-15 minutes)
to pickup more passengers along the way.
