Muang Champhone lies in the lowlands east of the Mekong, amid the streams and wetlands of the Xe Champhone. The river feeds a landscape of marshes, ponds and seasonally flooded forest before joining the Xe Bang Hieng. Fish and other aquatic life support the surrounding communities, and crocodiles inhabit the wetlands. In the Siamese–Vietnamese war of 1833–34, Siamese forces attacked Champhone along with other settlements of the region.
