Langtang is a region in the north-central Himalayas of the Bagmati province of Nepal. Situated 51 kilometres north of the Kathmandu Valley, the region is renowned for hosting the Langtang national park which eventually constitutes the border with the Tibet autonomous region of China. About 4,500 people reside inside the park (with Tamang as majority), and many more depend on it for timber and firewood.
