In reply to hairy51:
In the guides I have seen, the approach is on the right. I have done it twice, once on the right and once going straight up the gully. The right hand side was unpleasant and broken, the gully horrible and badly protected -esp when wet and slippy. Whatever approach to "The courtyard" I would suggest path of least resistance and quickest!
I am more intrigued as to how you describe the route after this. The prescribed route follows an exposed (obvious) ramp overlooking the gully before turning right by a fallen block and then up a steep 7m wall onto the ridge. I would describe this wall as the crux and akin it to V Diff climbing standard (we did it in the cold and wet). Once onto the ridge it is just exposed scrambling with a couple of exposed towers to negotiate.
The crux pitch you describe would not be the crux I remember? However the first time we did it, we didnt take the ramp, but continued up the gully for a few paces before climbing straight up to the ridge on steep slabs. Good fun too, but not as exposed as the other side.
Glyder Fach = Great scrambling area!
