Henrhyd Falls is the highest waterfall in South Wales, dropping approximately 90 feet (27 meters) into a wooded gorge within the Brecon Beacons National Park.

The Nant Llech river flows through surrounding forest before cascading over the cliff edge, and visitors can walk behind the falls to a large rock overhang at the base.

A footpath from the National Trust car park near Coelbren village leads down to the falls in roughly 30 minutes, with some steep and uneven terrain requiring sturdy footwear.

The site gained wider recognition as a filming location for The Dark Knight Rises , where the waterfall doubled as the exterior entrance to Batman's cave.
