The road starts on the B9128 at Hillend on an awkward bend under the foot of Lownie Hill which it negotiates by way of a couple of blind crests before heading east to Dunnichen along a near mile straight which ends at the wooded hamlet which is passed through by a narrow section of twisty road.
Back out in the open again, we head through a dip and reach a cemetery opposite the road to Letham, the C54 on the left. Straight ahead a junction is reached at the hamlet of Bowriefauld and we turn left here, followed almost immediately by a right turn which takes us out of the hamlet and downhill across the Vinny Burn.
The road climbs up Idvies Hill past the farms of Bractullo and Gask and the crossroads of the C53. Heading back the way, on a clear day, the mountain of Schiehallion can be seen on the western horizon as a perfect cone. We continue eastwards past Dumbarrow with the tall tower of the old windmill visible on the left, before heading downhill again and passing Boath Hill to reach the B961 at a staggered junction.
Passing over the northern shoulder of Cairnconan Hill, Arbroath and the Angus coast can be seen ahead as the road now heads markedly downhill past many farms in a south-easterly direction.
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, passing the Western Cemetery. 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.
