Nun Noc Mountain is located at the confluence of the Van River with the Dai River to the east of Ninh Binh City. The mountain is considered an important historical monument in Vietnam. It includes a group of ancient temples and caves. The mountain top was a favorite place for many Vietnamese poets who wrote a collection of poems. While they are at the top, the summit can be reached by a stone staircase divided into five levels and enjoy the scenic views at the top.
