Xieng Khaeng is a largely unexplored, stunning region with beautiful mountains, waterfalls and caves, embedded between mountains and the Mekong River. Only a couple of hours from Muang Sing town, the Akha and Tai Lue villages in this remote area have still kept their traditions and culture. Access to Xieng Khaeng is difficult and a local guide is required.

The northern-most extreme of the Mekong River in Laos is found in Muang Sing. As the Mekong rushes out of China into the Green Triangle bordering Myanmar, it makes its way through steep canyons before slowing down further south. This section can be accessed by boat from Xiengkok in Long District, but also by gravel road leading across the mountains from Muang Sing down to Xieng Khaeng. On this remote and beautiful stretch of the river are some of the oldest Tai Lue settlements in the district: Ban Xay and Ban Xieng Khaeng.
