Thanks for your thoughts, guys, and I think Owen is right. Having watched some more YouTube videos, it does now look very much like Bwlch Eryl Farchog that links Pen yr Helgi Du with Carnedd Llewelyn.
But boring? Not for someone like me who suffers from vertigo - both the phobia and the medical condition - as well as having bad balance to boot. Admittedly some sound in the video would help it, and the man's jacket collar was often in the way, but it really reminds me of what it's like plodding up a sharp mountain ridge in misty conditions and how scary to me the exposure can be.
