North Ridge Gully ^{Grade 1}

This is a short and relatively unknown route that offers a more adventurous way onto the North Ridge of Crib Goch than the usual Pen-y-Pass approach.

Begin at the campsite at Blaen-y-Nant and follow the path into the cwm. Stay left where it splits, aiming for the steep, dripping crag of Craig y Rhaeadr (which aptly translates as "Waterfall Crag"). Just to the left of the crag a waterfall issues from a wet gully.
The scramble ascends this. Depending on water levels either scramble up the stream or on damp rocks to its right bank. Continue upward on the right bank on a mix of heather and rock; much of the way is path marked. Further up the gradient eases.

Cross the stream where possible to the other side. A few outcrops offer some fun but beware of a huge difficult slab; follow the path to the left of this rather than climbing it.
Continue walking up on grass and scree until you reach the beginning of the North Ridge scramble proper.
