The bus routes are shown by area of the city that you want to go to/from.
Obviously, buses run their routes in both directions, so it's worth checking
that the bus is going where you think it is when you get on. Don't worry if
you don't recognise where to get off, the conductor will invariably tell you
(if you've told them where you're going). If not, ask other passengers, who
are normally very helpful. Some useful Thai phrases that you may need when
taking buses are shown here.
There has been a recent change in the numbering of the buses which we have
not yet changed on the pages. This is the sensible decision to put a number
5 in front of all the aircon buses, to avoid them having the same number as
the non-aircon buses which may run a completely different route. Therefore,
aircon bus number 11 is now bus 511 and so on.
