In reply to adam.brink:
I lived in Aviemore for about 4 years and in that time spent most of it driving away from the Cairngorms if I was going bouldering. The best 'local-ish' spots are the various venues in Strathnairn just south of Inverness (Ruthven, Farr, Brin etc), the Moray coast (Cummingston, Primrose Bay) and the stuff round Laggan. There's some really good stuff in all those areas and they're all within an hour or so drive from Aviemore.
There is stuff closer to the Cairngorms (e.g. Burnside, the Link Road boulder) but they're really only of local interest. Worth knowing about if you live there but not worth travelling for.
I see that there's a few things on Deeside mentioned in the latest Boulder Scotland guide but don't know anything about them.
