Highlights: The Water Yadan Geopark, located in the hinderland of Qaidam Basin, Haixi Prefecture, is a park featuring the Yadan landform. It was formed by the rising lake—Ginel—that gradually inundated the northern margin of the Yadan group, just like a vast ocean in the endless desert out of nowhere. Wind-eroded sandstones in different shapes and clear water are set against each other. With the sun shining on them, the pillars and their reflections appear to have risen to the midair, like magic castles suspended in the sky.
