Phileas :- "I enjoyed the walking but I have to admit Snowdinia doesn't excite me the way the Lake District does so I'm not likely to return to the area anytime soon."
Really? Oh well each to their own. I've never walked in the lakes but it does look good from the trip reports I've seen by other members, in fact very similar to some areas of the Brecon Beacons which I've walked virtually every inch of, but Snowdonia 'does' excite me, maybe you simply chose the wrong part of it for you.
Penygadair :- Yes I will avoid Cadair at the weekend, it's the same in my neck of the woods with Pen y Fan, Corn Du and Cribyn with tourists all over them like ants, I'm local so I know where to avoid the crowds. I will probably do something in the Rhinogs as part of the week and both myself and swmbo are very much looking forward to it.
As a footnote if you get down into mid Wales, there are some very remote almost wilderness type areas to walk, we have walked quite a few areas there now where if you see anyone else, it's unusual
