The classic North East Face route (5.6) is close to the skyline in this picture and well-worth doing, and there are other high quality trad routes at around 5.10 on the visible face.

You are right John, and those routes do look very fine. We actually climbed 'Sisyphus Summits' which is the epic and fully bolted 21 pitch 5.10d that follows the skyline to the very summit. One of the best rock routes I've climbed anywhere in world. I can't recommend it enough.
