Luang Namtha Province, one of the provinces of Laos,[4] covers an area of 9.325 kilômét vuông (3.600 sq mi).[5] The province is bordered by Vân Nam, Trung Quốc to the north, Oudomxai Province to the east and southeast, Bokeo Province to the southwest, and Burma to the west.[6]Notable settlements include Luang Namtha, Muang Sing, Ban Oua, Ban Lacha, Ban Tintok, Ban Ko, Pang Kalom, Ban Thang, Ban Nam Kanne, Ban Meo, Ban Pawi, Ban Sa Pouk, Ban He và Ban Tintok.

The Mekong river (Nam Khong) constitutes the northwest border of the province. Three large rivers drain westwards/southwards into the Mekong; Nam Tha, Nam Fa và Nam Long. The Phou mountain range runs along the China/Lao border, consisting of mainly dry evergreen forest.[2] The main roads in Luang Namtha province connect Houayxay in Bokeo with Luang Namtha town and Oudomxay with Boten. Boten is an important border crossing with China (Mohan), and provides an export route from China, via Xien Kok, loading from trucks into boats on the Mekong. Some of the best preserved monsoon forest (mixed deciduous forest) of Laos can be found in Nam Ha National Biodiversity Conservation Area. It has developed as a sustainable cultural and eco-tourism destination with the help of neighbouring countries, and several organizations including the European Union, UNESCO and the Lao National Tourism Administration. The eco-tourism activities involve trekking, river rafting, camping, kayaking, bird watching and mountain bike tours.[2]
