This is "not a mountain for the inexperienced". These are the words of the Snowdonia National Park Authority. The classic traverse of Crib Goch from East to West leads up from the Pyg track to a "bad step" where hands and feet are both needed briefly. It is followed by ascent to the arête, before tackling three rock-pinnacles to a grassy col at Bwlch Coch. This first part of the ridge is exposed with precipices below, having resulted in several fatalities, even of experienced mountaineers.
