Sayram Lake, Alpine lake in Tianshan Mountains, China

Sayram Lake is an endorheic alpine lake in the northern Tianshan Mountains of Börtala Mongol Autonomous Prefecture, Xinjiang, China. Its surface lies at 2,070 m and covers about 458 km², with a maximum depth of 110 m. The shoreline is straight and slightly trapezoidal, and the lake is fed by glacial meltwater, precipitation and groundwater.

The lake served as a key point along the northern branch of the Silk Road, where Saka nomads, Tocharians, and Göktürks established settlements in surrounding valleys. These early connections shaped the region for centuries.

Kazakh communities living near the lake maintain their traditional ways, with seasonal celebrations and stories passed down through generations of nomadic families. Visitors can directly encounter these living practices and the strong connection between people and the water.

The best time to visit is from May through early October, when temperatures remain mild and roads are accessible. It is important to allow plenty of travel time from the nearest city and bring weather-appropriate clothing.

The lake had no fish at all until stocking began in 1976, and early attempts largely failed. From the 1990s, 16 species became established, among them peled, arctic cisco and ide. Sayram is now one of China's best-known cold-water aquaculture bases, with about a dozen species sold on the market.
