Waterfall Country.
Known in Welsh as Coed-y-Rhaeadr (Wood of the Water), Waterfall Country lies within the triangle formed by the villages of Hirwaun, Ystradfellte, and Pontneddfechan. Collectively the falls are one of the most popular natural attractions in South Wales, a fact which has brought about problems of erosion in the vicinity of many of the falls. Most occupy locations designated as sites of special scientific interest or as special areas of conservation which aim to protect the biodiversity and geodiversity of these sites.
