Grey limestone or grey beards? Cambrian Grey climbs up solid, limestone edges to a point below the roofs and it is the second climb you encounter after crossing the stream. A good, well-protected route.
Great little crimpy moves up this limestone face. The route never gets overhung and so it is more balance than anything.
There has been a second pitch added above this one. Do a hanging belay off the first pitch anchors and go for it. There are a couple 5.10 moves, but overall much easier than the first pitch.
The second pitch has well spaced bolts and a double chain anchor.
I put up the second pitch with my friend Tristan before he left for his mission to Russia. I always wanted to drill a few more bolts above the big roof. We thought that the bolts up to the roof were fine. We didn't plan to run it out so much but the climbing was easy and we ran out of hangers. The slab was longer than it looked from the ground. If someone gets there before I get back I don't care if they add two bolts in the blank spaces up high.
Actually, the first ascent for Cambrian Grey was done by Chris Laycock back in like 89 or 90. Bug Barn Dance Wall was called Cambrian Wall by the locals until Phil and Andy Reynolds filled the rest of the wall with routes.
