In reply to martinlird: Crib Goch is definitely more exposed and needs a bit of extra care, and forethought than Striding Edge. Both are still enjoyable days. I really enjoyed my day on GG, even managing to bypass the crowds and manage to get it pretty much to myself.
Going up in late afternoon, knowing my decent would be in the dark, and well prepared for that meant I had most of the ridge to myself. Managed to get most of the way around the horseshoe before needing to pull out my head torch.
I would hate to have done it with crowds.
