Phong Nam Karst landscape

Non nuoc Cao Bang Geopark is beautified with majestic and peaceful landscapes. The diversity of Karst topography created exceptional karst landscapes in Non nuoc Cao Bang Geopark such as Thang Hen lake system, Nguom Ngao cave, Ban Gioc waterfall, karst fields in the eastern part of the  Geopark like Phong Nam or Ngoc Con.

One of the karst landscapes presenting the diversity of karst evolution in Non nuoc Cao Bang is the karst field in Phong Nam commune, Trung Khanh district. Karst landscapes in Non nuoc Cao Bang Geopark present a full cycle of karst evolution from primitive to young, mature and senescent phases. The senescent karst in Phong Nam is a typical feature of karst topography in Non nuoc Cao Bang Geopark, adding natural beauty to the picture of a wonderland.

The features of karst landmarks in this area are formed by fault activities in the past and the impacts of weather, and gravity that carved and sculptured the rock into a variety of landscapes in the same area. Phong Nam karst landscape is a amazing geological heritage demonstrating clearly karst evolution processes in tropical environment. The deep dissection of a positive moving limestone massive over millions of years resulted in specific landscapes of tower karst, cone karst and valley. Phong Nam karst landscape is of scientific significance presenting the karst evolution over different phases from young to mature; in combination with the impacts of tectonic movements resulting in the current topography.
