Graig Llech Woods occupy the wooded gorge carved by the Nant Llech, as it makes its way to join the River Tawe. The trail through the woods leads to one of South Wales' most spectacular waterfalls, Henrhyd. This 90-foot (27 m) cascade was used as the entrance to the Bat Cave in Christopher Nolan's 2012 blockbuster The Dark Knight Rises.
