Thailand has a wide array of transportation options. There are subways, taxis, and buses, just like most cities in the world. Like other parts of Southeast Asia, there are also tuk-tuks. However, one thing that I have never ridden before is the water taxi.
In Bangkok, the river seems to be everywhere. Transportation has grown along the river, with small docks interspersed along its length just like bus stops along a road. The river taxis have a number of lines, each with set stops along the way. After boarding, ticket collectors come along with little wooden boxes to take your fare.
The boats can be pretty full, and it makes an interesting experience when there are no water taxis where you come from…
