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.

Not that much to add here, basically this is a great place to go on a rainy day, or to visit as a rest stop on a bike ride up the Swansea Valley. There is also a great nearby campsite/motorhome venue stay, if you are thinking of staying overnight.
