Moon Hill (YueLiang Shan) lies a few kilometers outside YangShuo.
Moon Hill is so named for a wide, semicircular hole through the hill; the remains of what was once a limestone cave. The arch is about 50 meters in height. With an elevation of 380 meters, the hill is 230 meters in relative height and 410 meters in length.
It takes about 20 minutes to walk up to the arch; longer for those who wish to reach the hill's summit. There are over 800 marble stairs leading to the cave, though other more peaceful, but more rustic, routes are also available.
