In reply to Skyfall:
The Gribin is a lot easier than the NNE ridge of Y Garn and The devils kitchen.
The NNE ridge of Y Garn is quite exposed along the top and has a couple of bad steps.
The Gribin is only just a step up from walking.
If theyre a novice and you feel confident theyll get up a grade 2 scramble mabe the ridge to the right of Idwal slabs, then seniors ridge, then descend the Gribin. Or you could just do seniors ridge then descend the Gribin at grade 1.
