The C12 starts on the B818 at Langbank in Carron Glen and heads south, winding along the eastern flank of Darrach Hill. After a series of unsigned and unlined junctions, the road reaches Drumbowie Reservoir, and runs along its north shore before turning south across the grassy dam. It then comes to an end on the C26 at the south end of the dam.
