This is a good option if you want to travel between towns or provinces. The national bus stations are called Bor Kor Sor (it is a Thai acronym that literally stands for 'business that sends people'). There is a Bor Kor Sor station in Khuk Khak near the market. There are also Bor Kor Sor stations in Phang Nga Town and Takua Pa.

There are three classes of bus - standard, first class and VIP. Do not take a standard bus for a long journey. The seats are hard and they do not have toilets. The first class buses are comfortable and have toilets but they can be slow going as they stop to pick up passengers all along the route. For long journeys, the VIP buses are worth the extra cost with comfortable seats, plenty of leg-room and no unscheduled stops. The leg-room on the VIP buses varies depending on how many seats the bus has. The 24 seat VIP buses are highly recommended but even the 32 and 36 seat VIP buses are comfortable.
