Located amid the Tianshan Mountains in northwest Xinjiang, Tianchi (Celestial) Lake is believed to be a divine pool in Chinese mythology. As a classic example of both a glacial barrier and a moraine lake, the crystal clear waters reflect the surrounding snow-capped mountains and thick Chinese spruce forests. Walking along the wooden walkways through the trees, tourists can immerse themselves in this natural oxygen bar that is home to nearly a thousand species of wild flora and fauna.
