Located in the heart of the Tengger Desert in Alxa Left Banner, Inner Mongolia, at an altitude of 1,320 meters, Sun Lake, along with Moon Lake and Star Lake, forms a "three-pearl chain" of the desert, encompassing 3.2 square kilometers. White crystals precipitate from the lakebed, creating a vibrant blue like a gem inlaid with golden sand in summer. In winter, the cracked ice creates a texture resembling glass. Aerial photography creates a striking contrast of red and blue with the neighboring Wulan Lake ("Heart of the Earth"). Reeds thicken the lakeshore, attracting hundreds of migratory birds, including swans and ruddy pochards, from March to April and September to October. The sand dunes and oasis create an "oasis of life in a sea of death."
Suitable season for visiting:
1. Summer and Autumn: June to August,
the Milky Way falls on the lake and migratory birds dance over the sand dunes.
2. Late Autumn: Late September to mid-October
, the clear sky rate is over 90%, and the lake is like a mirror reflecting the sand dunes.
3. Winter: December to February,
blue ice cracks and rime surround the lake.
Recommended places to visit:
1. West Coast Observatory
In a light-pollution-free environment, I set up a tripod to shoot the "star trails in the lake" and used my phone to fill in the light to shoot portrait silhouettes while wearing a red long skirt.
2. Sunset Point, Sand Ridge
Climbing to the top of the sand dunes on the south side of the lake, the sand ridges are like molten gold blades at sunset. The wide-angle lens captures the three-dimensional image of "sand dune curves + blue mirror of the lake + snow-capped peaks of Helan Mountain".
3. Explore the Reed Maze
Take a herdsman's raft through the reed marshes and observe migratory birds nesting up close.
