In reply to Joe Mackenzie:
Lived near Kinross for a while and explored the nearest bits of rock quite a bit.
Ravenscraig is okay, though it's more of a 'go to the beach and play around on the rocks' kind of venue, rather than a class bouldering venue. A lot of the sandstone holds are pretty eroded and the level of the ground changes quite a bit (last time I went the ground was about a foot higher than in the photos I'd seen).
Wolfcrag is your best bet - lots of good stuff there, and countless eliminates. Obviously a bit further out the way though.
All the stuff in the Lomonds I explored was pretty chossy, and wouldn't really lend itself to bouldering - more chossy VS cracks.
Craiglug in Fife is okay - a few wee boulder problems, and some short easy solos if you're into that. Probably not worth more than an afternoon though, and no hard routes.
Obviously north of Perth up the A9 and out towards Stirling there are quite a few options - Dunkeld, Camby etc. but probably a bit far away for what you're looking for.
Limekilns is okay for traversing / solos and the odd slightly contrived boulder problem, but it sounds like access is problematic there at the moment, so best avoided.
Never explored Powmill, though from what I've heard it's all very small and a bit disappointing. Probably worth at least checking out though, as it's pretty close to Kinross. Likewise with Craigencat - never been, but is dead close and probably worth scoping out.
You could probably take a pad to Rosyth Quarry and do some traversing / boulder out some starts and make up some eliminates if you were really desperate, though the place might be a bit full of airguns/bottles/neds etc. at the moment with the schools off.
