In reply to Dan Arkle:
I was talking to someone about this crag the other day.
As you say, it's a great venue - feels kind of hidden - with that beautiful drive past Llyn Geirionydd on the way in, feels like you're re-discovering a long lost part of Snowdonia.
As for the routes, they're all amazing, but I still maintain that the grades of Astoroth (E2 5c) and Phoenix (E2 5c) are an absolute joke. When I first did Astoroth I thought it was E4 6a, which may have been a bit of an exaggeration, but goes to show the torrid time I had on it. Phoenix is just as bad, with a really awkward, off-balance, and surprisingly hard to protect start it's basically E3 all the way in my opinion. Things got a bit more logical once you got to E4, but that's not to say they were easy for the grade!
