Park designated in 1957 in order that its landscapes be protected and for the quiet enjoyment of them by the public. Subsequently, considerable parts of the gorge have also been protected for their wildlife and habitats, including the Cwm Clydach SSSI, Cwm Clydach National Nature Reserve, the Cwm Clydach Woodlands SAC and the Usk Bat Sites SAC, which also extends across much of the neighbouring Mynydd Llangatwg. There are, in addition, numerous scheduled ancient monuments within the gorge, representing a history of human occupation from the Iron Age to the Industrial Revolution. Though the gorge is not included within it, the Blaenavon Industrial Landscape, a World Heritage Site, adjoins the area. The current (2010) Forgotten Landscapes Project includes both the WHS and the Gorge within a wider area. The Project seeks to conserve and restore the built features of an area which was key to the Industrial Revolution.
