Because of its mountainous topography and lack of development, Laos has few reliable transportation routes. This inaccessibility has historically limited the ability of any government to maintain a presence in areas distant from the national or provincial capitals and has limited interchange and communication among villages and ethnic groups (see Transportation and Telecommunications , ch. 3). The Mekong and Nam Ou are the only natural channels suitable for large-draft boat transportation, and from December through May low water limits the size of the craft that may be used over many routes. Laotians in lowland villages located on the banks of smaller rivers have traditionally traveled in pirogues for fishing, trading, and visiting up and down the river for limited distances. Otherwise, travel is by ox-cart over level terrain or by foot. The steep mountains and lack of roads have caused upland ethnic groups to rely entirely on pack baskets and horse packing for transportation.

The road system is not extensive. However, a rudimentary network begun under French colonial rule and continued from the 1950s has provided an important means of increased intervillage communication, movement of market goods, and a focus for new settlements. In mid-1994, travel in most areas was difficult and expensive, and most Laotians traveled only limited distances, if at all. As a result of ongoing improvements in the road system during the early 1990s, however, it is expected that in the future villagers will more easily be able to seek medical care, send children to schools at district centers, and work outside the village.
