Zhaosu Jade Lake, nestled deep in the Aheyazi Valley of Zhaosu County, Ili Prefecture, is a rare alpine lake in the heart of the Tianshan Mountains, known as the "Sapphire Lost by the Tianshan Mountains." Formed by glacial meltwater, the lake's suspended glacial rock powder constantly changes color with the seasons and sunlight. In spring and summer, it's a vibrant green, gradually transforming into a deep blue in autumn, its appearance changing daily. Climbing to the Yujingtian Peak viewing platform, one can overlook the long, narrow, turquoise lake nestled quietly among majestic mountains. In the distance, snow-capped peaks stretch endlessly, cliffs are rugged, and the lakeshore is covered in open meadows where cattle and horses roam freely, creating a tranquil yet awe-inspiring atmosphere. The scenic area allows self-driving entry, with a route that follows the valley in a round trip, allowing for frequent stops for scenic views. The deeper into the valley, the more pristine the natural environment becomes. Compared to the more popular tourist destinations in Ili, this area is much less crowded and less noisy, perfect for quietly appreciating the lake and mountains. Temperatures are low in the high-altitude valleys; even in the height of summer, the mountain winds remain chilly, so be sure to bring a thick jacket. The ultraviolet radiation is also strong, so sun protection is essential. If you visit Yuhu Lake after your trip to Xiatu, you can fully experience the unique tranquility and vastness of Zhaosu, making it a hidden gem on the Yili loop that you shouldn't miss.
