From Frances Hood's book - but you may want to check out Canmore (at http://www.rcahms.gov.uk/pls/portal/PORTAL.wwa_app_module.show?p_sessionid=109920&p_header=true) for more info, longer grid refs and detailed maps.

Where there is more than one carved rock in an area, a "central" grid ref is given here.

NR704403 Low Clachaig ("best in Kintyre")
NR693418 North Beachmore
NR734522 Ballochroy
NR705369 Blary
NR718444 Braids
NR707445 Drumnamucklach
NR677383 Glencreggan
NR694378 Killmaluag
NR669309 Killocraw

Not spectacular sites and not too accessible. So bear in mind follow that cow's advice that the Kilmartin stuff, if you haven't seen it, is only about an hour's drive away. Go there if you want to see C&R at its best.
