This article is about the Class III road numbered C51 maintained by Angus Council.
For other roads numbered C51, see C51
The C51 starts on the B9128 at Hillend near Forfar and heads east to Dunnichen, turning south east as it meanders across the landscape past scattered houses and farms. The B961 is crossed below Boath Hill, and the route continues towards Arbroath. At Woodville Feus, instead of continuing the short distance to the A933, the route appears to turn right, parallel to the main road, to reach Arbroath. In the past, the route probably followed Gallowden Road into the town, but at least part of this is now the C601, so it is not entirely clear where the C51 now ends.
