Moon Hill (chin.月亮山, Pinyin: Yuèliàng Shān) or Moon Mountain is a hill with a natural moon-shaped hole through it a few kilometers outside Yangshuo. On a sunny day, blue sky and white clouds can be seen through the cave and on cloudy and rainy days, the "moon" is deep in mist. Viewed from different angles, the moon takes on different shapes, just as the moon changes shape with the elapse of time, sometimes full moon, sometimes half-moon and sometimes crescent, forming a marvelous spectacle in Yangshuo. This is one of the major charms of Yangshuo.

With an elevation of 380 meters, the hill is 230 meters in relative height and 410 meters in length. Climbing about 800 steps up to the very top, the moon hill offers some broad, fantastic panoramic views of the surrounding countryside, which is characterized by the knobby karst hills found throughout the region.
