I do not even own a bike but this short movie was pretty cool - Danny Macaskill: The Ridge.
"...where he returns home to the Isle of Skye to conquer the notorious Cuillin Ridgeline."

It is mainly on a bike but there are a couple of bits where he walks.
I have not been to the western arthurs but the scenery does not look to unlike the photos I have seen on this forum.
