In reply to HoffiDringo:
I moved to Carlisle quite a few years ago, albeit I work in Carlisle so my commute is 5 minutes by foot.
The climbing is good, like others have mentioned it's close to the lakes, as well as the county. As a weekend warrior having the choice of the two had been great, as they're all reasonable day trips, and if you want to stay away for a night it's also perfectly possible. North Yorkshire isn't entirely unreasonable either. It's provided us with a lot of good climbing and there's nearly always somewhere to go to escape the tourists, especially during holiday periods. Also, living relatively close to crags that are very easy to walk into means taking a couple lamps and having a night session is very easy.
Indoor wise Eden rock is as good as it gets for bouldering, for lead climbing though I think most people end up in Kendal.
All that said from the viewpoint of a boulderer who only ties in once every few years if that.
For living, I've toyed with the idea of moving to Penrith or somewhere outside of Carlisle. However my partner and I have decided that we'll probably stay in Carlisle, as houses are reasonably priced, access to the M6 as well as Newcastle/Scotland/Manchester etc are all relatively easy, and there's a bit more to do for my parents when they visit from overseas as they can't drive. Some bits here are crap, but overall, it's no worse than most places that I've lived in the UK.
Plenty people I know commute in either direction so it's fine.
Either you live in you'll find plenty people to climb with, there's nearly always someone keen!
