Where is this gill and was it any good?

Start at the campsite at Blaen y Nant in the Llanberis Pass and walk up to Craig y Rhaeadr. There's a gully to the left of the crag which you climb. One or two falls couldn't be climbed and had to be avoided. Higher up we took a right hand branch which was much drier. I thought it was pretty good fun, maybe grade 2 but very slimy (obviously!). Makes a good approach to doing Clogwyn y Person Arete. There are more pics here:

Thanks for that, it looks fun
