Songtaew
A Songtaew (สองแถว), literally means “two rows,” is a transformed pick-up truck with a row of bench seats on the sides of the back. Sometimes there is an additional seat in between where you have to sit backward.
Some travel destinations have Songtaews operated as local buses and they seem to be the most economical way to travel in a short distance. Before taking a ride, see if there is anyone in the back and check the price. If there is no one in the back to share the ride, chances that you might be over-charged.
