Kỳ Sơn
Kỳ Sơn lies in the high mountains of western Nghệ An, where valleys and passes connect the upper Cả basin with the Lao highlands. Steep, forested ridges separate the communities of this frontier country, and streams descend towards the great river that flows east to the Vietnamese coast. Tai-speaking peoples and their neighbours inhabit valleys and uplands across this mountainous region.
