Coal mining was an industry in the valley with mining operations being located at Aberpergwm and Pentreclwydau near Glynneath.^[1]

"Waterfall Country" is a nickname given to the Vale of Neath due to the diverse number of waterfalls in the valley.^[2][3] In the upper reaches of the valley, at the foothills of the Brecon Beacons, are the waterfalls of four or five rivers: the Afon Hepste, Nedd Fechan, Afon Pyrddin, Afon Mellte and Afon Sychryd. In the lower valley, waterfalls can be found at Melincourt and Aberdulais.

Currently partly used as a goods line the Vale of Neath Railway once served the area for passenger trains.
