Turpan

Desert oasis 150 km southeast of Urumqi at -154m below sea level — the lowest point in China. Jiaohe ancient ruins, Bezeklik Buddhist caves, the Karez well system, Flaming Mountains, and the country's grape capital.

Turpan sits in the Turpan Depression, the second-lowest point on Earth after the Dead Sea, at -154m. The combination of desert climate, abundant snow-melt water from the Tianshan Mountains delivered through the 2,000-year-old Karez underground irrigation channels, and intense summer heat (45°C+ in July) makes Turpan China's premier grape-growing region.

Jiaohe (the 'River-Confluence City'), 10 km west of Turpan, is one of the world's best-preserved earthen ruins — a Han through Tang-era city excavated rather than built, with house foundations, temples and government compounds visible across 50 hectares. Gaochang ruins, 30 km east, were the capital of the Uyghur Khaganate from the 9th-13th centuries.

The Bezeklik Caves contain Tang-era Buddhist murals, though many were removed by early 20th-century European archaeological expeditions. The Flaming Mountains (sandstone hills with red iron oxide) feature in the Tang novel 'Journey to the West'.
