Inspired by the picture of George Smith on The Wall Within in the Ground Up guide, James Williams sought out the stunning route in the heart of the slate quarries after lockdown.
He told UKC: 'Me and Will Clarke went up for a look one day and abbed down the line from the tunnel. There was a fair amount of bright red lichen on the route which would brush off and blow into your eyes! But once that was cleaned off we were met with a line of perfect edges and side pulls which were actually quite big, but in true slate-style, the feet were pretty rubbish. And unlike any slate route I'd been on before, it was overhanging the whole way by about 10 degrees. The rock quality is really good, and the moves are even better! It's a little bit loose before gaining the first bolt, but after that everything is bomber.'
