Dubbed the “Pearl of the Tianshan Mountains,” Sayram Lake is China’s highest alpine lake (2,073 meters) and a UNESCO-designated Biosphere Reserve. Shimmering turquoise waters stretch 458 km², surrounded by snow-capped peaks, wildflower meadows, and Kazakh nomadic herds. Revered as a “Holy Sea” since ancient Silk Road times, it’s a sanctuary for swans, eagles, and the endangered Tianshan snow lotus.
