Henrhyd Falls (Welsh: Sgwd Henrhyd) in the Brecon Beacons National Park, Wales, is the tallest waterfall in southern Wales with a drop of 90 feet (27 m). It lies on National Trust land, in the county of Powys.
Geology
The falls occur where the small river, the Nant Llech (grid reference SN854122) drops over the faulted edge of a hard sandstone known as the Farewell Rock which forms the top half of the rock face and which forms the base of the South Wales Coal Measures. Beneath this, and forming much of the recessed portion of the drop, is the Subcrenatum Sandstone separated from the Farewell Rock above by the Subcrenatum marine band. Both the marine band and sandstone are part of the Bishopston Mudstone Formation included within the Marros Group[1] A stream gully between the descent path and the falls marks the line of the Henrhyd Fault which is responsible for the falls' presence.[2] The nearest settlement to it is Coelbren, on the road between Glynneath and Abercraf. Though not in the core of the area, it is considered by many to constitute a part of Wales' celebrated Waterfall Country.[3][4]
Access
The waterfall is reached after a steep walk down into the valley from the car park established by the National Trust, and is a popular spot to visit. One of the area's most famous visitors was Sir William Edmond Logan (later head of the Geological Survey of Canada), who carried out detailed geological survey work in the area, discovering near the foot of the falls the fossil trees which now stand outside Swansea Museum.
The final scene of The Dark Knight Rises was filmed at the waterfall, where it doubled as the entrance for the Batcave.
