Located at the foot of the snow-capped Tianshan Mountain Range, Urumqi is the capital of Xinjiang Uyghur Autonomous Region in the northwest of China. The place became well known to foreign visitors as the last stopover along the Silk Road. Though Urumqi is located in the temperate zone and has a mild continental climate, there is a great difference in temperature between day and night: a coat or sweater is needed during the night even in the hot summer. The best time to travel the region is from May to October. Urumqi is a diverse multinational city, home to 43 ethnic groups: Han, Uyghur, Hui, Kazak, Manchu, Sala and Mongolian people are well represented here, and have been for hundreds of years. During the Han Dynasty, Urumqi was a heavily guarded fort; during the time of the Silk Road, Urumqi became an important stopover. Now, Urumqi hosts many China tours with its exciting cultural attractions, including the Red Hill, South Pasture, the HeavenlyLake and the XinjiangAutonomousRegionMuseum.
