In big cities in Laos, such as Vientiane, Luang Prabang, Savannakhet and Pakse, there are some taxies that are mainly concentrated in the airports. There are no taximeters in taxies. Thus, tourists need to negotiate on the taxi fee in advance, generally costing 0.5 dollars per kilometer. The taxiesof the city are comfortable but expensive. Tricycles and motorcycles are relatively cheap with the fee of 200 Kip per kilometer. However, taking tricycles and motorcycles are not so comfortable. Bicycles are one of the most popular vehicles in Laos. Bicycles can be seen almost everywhere in Laos with the rent of about 3,000 Kip. In big cities, there are many motorbikes that are rented.
