Luang Namtha is the northeastern most province of Laos, remote and an up-coming eco-tourism destination. It shares a common border with China (north) and Thailand (west). It's still very much a back packers' paradise, and can be reached by road via Luang Prabhang-Oudamxai ( a back breaking ride ), or by air from Vientiane or Luang Prabhang.
The main roads in Louang Namtha province connect Houaxai in Bokeo with Louang Namtha town and Oudomxay with Boten. Boten is an important border crossing with China (Jinghong), and provides an export route from China, via Xien Kok, loading from trucks into boats on the Mekong
