The falls were discovered by Europeans in 1870 by a party led by Charles Barrington Brown, a British geologist appointed as a government surveyor to the colony of British Guiana.

Waterfall Country (Wales) now part of the unitary authority of Powys. A few miles further west are Henrhyd Falls on the Nant Llech, a tributary of the Tawe and to the southwest are Melin Court Falls on the Melin Court Brook, a tributary of the River Neath. These, along with Aberdulais Falls on the Dulais, a further tributary of the Neath are also encompassed by the term 'Waterfall/s Country' by some writers. 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.
