In reply to timparkin:
The first section is just a walk under the rhyolyte band. Easy, but with a great views.
We screwed up by glancing at the diagram in our book, misinterpreting it, ignoring the text and going up Great Gully rather than crossing it. We made it but IMHO it is dangerous without a rope. Climbing up to vdiff on wet slabby rock with a memorable vertical moss pitch. Don't do that.
Once you are on top it there's a pleasant ridge walk followed by a slabby downclimb then more walking. Good scenery but not really technical. I don't remember any particular difficulties there but anything would seem nice after the gully
I would say the parts of it I have done were pleasant and not particularly technical with an emphasis on walking rather than climbing but I can't talk about the ascent through the rhyolite band as I haven't actually done that bit.
I think "loose, exposed walking" would probably be fair but would add "in excellent locations".
