In reply to Jay81:
Have only been to a few crags in the Dumfries area, all trad.
Cliffton is a good single pitch granite crag with lots of routes sub E1.
Meikle Ross on the coast near Kirkcudbright has some good single and multi pitch routes on Greywache mostly non tidal.
The Thirlstane is worth a look with its sea arch, routes and some bouldering.
Corwar is a superb hidden granite slab near Newton Stewart and the biking centre of Kirroughtree.
Check out John Biggar web site as it is a wealth of information on the crags in the area with topos
The SMC guide Lowland Outcrops may be worth getting as well.
Lots of other good spots along the coast as far as Stranraer and mountain crags in the Galloway hills.
