There's numerous wee routes on it and some are quite hard. Beware of dodgy belays and loose rocks. Alternative 'nearby' crags include Creag a' Barns at Dunkeld. This has the steep and difficult overhanging wall of Upper Cave Crag containing classics such as Rat Race, Rat catcher and Warfarin' as well as several sport lines of about F7b-F7c standard. The other crag is the slabby Polney, with many 3 star VSs and enjoyable low grade routes.
Access is possible by bus or train.
Finally, Ratho Quarry. Well, its an Edinburgh outcrop but the routes are interesting. E5 6b which people seem to try only because it has a peg on the crux.
