Today brought us good sunny weather with a light wind so Caff and I headed up to Diffwys Ddu (Cyrn Las Grey Horn) in Llanberis Pass. I had not been up here before so it was good to get up here while it is dry. Caff had only a couple of routes to do before he had done all the routes on this crag. We started up on The Grooves (E1 5b) and we finished on The Undercut (E5 6b), a route which hasnt had a second ascent. The route had plenty of pegs which are all in great condition with some great pumpy climbing. We then headed back to the bags for a bit of a refuel and I led up The Skull (E4 6a) and Caff went for Wrath of Khan (E6 6b) which takes a groove to the right of pitch 5 on the Skull. Again another route which hasnt had a second ascent. A great day finished with a pint in the Vaynol Arms.
