In reply to Rory Shaw: "SH6108255163 From the cairn, descend and scramble along the ridge in an easterly direction. The right-hand side of the ridge for this section is much less exposed than the other side. The first major obstacles to be reached are known as the Crib Goch Pinnacles. The easiest way to navigate these is to make your way around the first pinnacle on its right hand side before ascending it to its top. Descend the other side with care along a narrow rock shelf to the safety of a gully. This section is very exposed! Climb up the gully and ascend the second pinnacle up its left hand side. After another 200 metres you should reach a small pile of stones that mark the true summit if Crib Goch."
The left hand side is where you want to be as you decsend CyD anyway, but then the nose provides a short section of scrambling which can be tricky. The description glosses over this section which is still pretty dangerous and exposed.
I also think climb the first pinnacle. Around the side seems more dangerous to me and up and over easy and secure, just exposed. I often traverse the second pinnacle, climb to the true summit and back track to bwlch coch.
