I've never been and I'm considering going tomorrow. Looking for mid-grade trad and sport. I'm driving from SW London, so it's a bit of a trek, but so are all the alternatives.
The sports crags on the northern side will be busy.
But the engine and revving noise from the Imprezza and/or Evo clubs and/or boy racers and/or bikers is usually the worst thing about Ched (even worse than driving through the eateries and shops on the way up).
Thanks for your input, guys. We ended up at Canadian Wall and The Narrows. We had both places to ourselves; not a single climber. The boy racer noise was pretty impressive.
