Man unloading oranges from a cargo boat on the Mekong River.<br /> 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. 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.<br /> <br /> Luang Prabang, Laos, 2010.
