Motuo is a county as well as a traditional region of the Linzhi Prefecture in the  southeast of Tibet Autonomous Region of People’s Republic of China,covering an area of 30,553 km2. In Tibetan language,it means “flower”.It further stretches across McMahon Line into neighboring Upper Siang district of Arunachal Pradesh.

Motuo is located in the average altitude ranging from 1,000–3,500 metres (3,300–11,500 ft) above seas level. It covers 30,000 square kilometres (12,000 sq mi) stretching from south of Kongpoand Powo (Bomê) through the lower Yarlung Tsangpo River into Arunachal Pradesh, surrounded by high mountains: the tallest is Namcha Barwa at 7,782 metres (25,531 ft)). Motuo has lush vegetation and many species of wild animals. Unlike other parts of Tibet, it receives plenty of rain, and has diverse biomes: there are subalpine coniferous forests in the north and temperate coniferous forest in the south in the low-lying area of the Yarlung Tsangpo gorges.

Motuo used to be the last county without permanent road access in Tibet, due to the landscape of several high-elevation mountain ranges. A first, simple road was built in 1970s, yet it was usually blocked by ice and snow on the mountains in the winter, making it only accessible seasonally. In December 2010, the Chinese government announced a project to renovate the road into a permanent highway from Bomê to Motuo County,[2] including excavation of a new tunnel under the mountain range. The renovation was completed in 2013.
Before the completion of the highway, transportation in Motuo primarily relied on foot. Hiking to Motuo is also a popular activity among tourists, although Motuo hiking is generally considered highly exhausting and risky.
