The province is bordered by Vietnam to the north, east and southeast, Xiangkhouang Province to the south and southwest, and Luang Prabang Province to the west. The terrain is rugged, with dense mountainous forest forming much of the province, particularly on the western side. Houaphanh Province is one of the poorest areas of Laos. Numerous socio-economic problems plague the province, with an infant mortality rate and access to safe water and medical facilities far worse than the national average.
