We stopped for a 'proper' look for the first time in twenty years this May. Fantastic displays by the Lammergeiers and some smaller raptors, pigeons rather sensibly sticking to the base of the gorge! My wife eventually dragged me away but I could have watched all day.
Saw a young Golden Eagle here also a couple of years ago. I have seen images of these things but the reality is so much more striking - their wings are huge!
As suggested above, well worth a look if this is your thing.
