travel agencies will be able to sell an all-in-one ticket from
Bangkok to Koh PhaNgan which includes the bus and ferry ticket
for about 650 Baht per person. The price is low because the journey
takes all night and is the least comfortable way to travel. Buses
depart from Bangkok at around 7pm, arriving eary morning in Suratthani
in time for the first ferry to the islands. Coming back, there
are numerous ferries, but for the bus you will need to depart
no later than 1pm. Usually a shuttle bus will drop passengers
off in Suratthani to wait until about 7pm at which time the bus
will depart to Bangkok. As a more convenient option consider buying
a ticket on the well-organised Goverment Bus which actually goes
on the Raja Ferry and saves time and discomfort changing modes
of transport - although it is more expensive and will set you
back up to 1,000 Baht.
are also several other bus routes (mostly via mini-bus) linking
Suratthani with other major destinations.
