According to the local press, Brecon Beacons in Wales is to be used as the new waterfall entrance to a rebuilt Batcave that will be used for the opening sequence of The Dark Knight Rises. Apparently the scene will involve Christian Bale's Bruce Wayne 'discovering' his new cave, the interiors of which have been built on a sound stage in Los Angeles. The Batcave is of course a massive part of The Caped Crusader's mythology and was a memorable setting in Batman Begins, which similarly had a waterfall entrance. There was no Batcave in the sequel as Wayne Manor had been burned down to the ground and was yet to be rebuilt but as The Dark Knight Rises... so too shall his new home. 
Here's what the insider said to Wales Online;
One insider who witnessed the filming said: They were there for a couple of days just a few weeks ago. I understand its going to be used in the opening sequence of the film, as Batman discovers the Batcave.
