In reply to Jamie Wakeham:
Thanks, both. Yes, it was the suggestion of DYLs that was in my mind - glad they haven't gone ahead with that!
I'm driving up with a novice on Sunday morning, doing some gear shopping faff in Llanberis, and figured that The Sidings would be a good place to start off. Is the upper parking a good shout for that? I don't know the quarries terribly well so maybe better if I use the main parking area.
I'm hoping that parking will be a little easier midweek for Ogwen...
