WALES (THE GUARDIAN) - A trail leading to a stunning waterfall in Wales, which features as the entrance to the Bat Cave in the blockbuster film Batman: The Dark Knight Rises, has had work completed that will make it more accessible to visitors.

Henrhyd Falls in the Brecon Beacons has become a popular attraction for Batman fans eager to experience a walk behind the 27-metre-high curtain of water that conceals the entrance to the superhero's hideout in the 2012 film.

As well as being the tallest in south Wales, the waterfall, which is owned and managed by National Trust Wales, is a Site of Special Scientific Interest.

In order to accommodate more visitors without risking damage to the unique environment, a series of steps - as well as a 40-metre boardwalk - are among the changes at the site and the the Nant Llech Trail that leads walkers through the falls.

Judith Harvey, wardens manager for Brecon Beacons national park authority, said: "There has been a steady increase in visitors to the Nant Llech Trail and Henrhyd waterfall making it a popular walking destination in the Brecon Beacons. With work now complete, it means that people for many generations to come can really enjoy what Abercraf and the surrounding area has to offer, safe in the knowledge that they are not causing any damage."

Brecon Beacons national park has been a location for many film and television series, including Doctor Who, the Hitchhikers Guide To The Galaxy and Merlin.

According to park authorities, they receive several enquiries about filming every day and there are currently six production teams scouting the area.
