In reply to FredMead:
Firstly Portland is crap, that's why let all yous sport climbers bolt it in the first place.
Secondly Scotland has some amazing mountain routes and mountain cragging, but where ever you live you have to be prepared to travel around 2-3 hours to fully appreciate it, so it doesn't matter so much where is Scotland you live. Just go climb at places like Glen Nevis, Dubh Loch, Loch A'an Basin, Glen Etive, The Buchaille, and feel the quality. It kicks the crap out of the SW many many times over (with the exception of West Penwith, pembroke and Lundy, which are amazing venues in there own right)
Thirdly the lowland cragging in Scotland ain't that great, there are some good locations but few big *** locations with tonnes to do, but you do have quite a bit within just over an hours drive from st andrews. Perhaps not enough to last you much over 2 years before you get bored though.
Finally the bouldering here is limited.
