The C43B starts at a fork on the A950 at Flushing, and heads north east, turning east as it skirts the northern boundary of Longside Airfield. It then reaches the scattered village of Inverugie, where it turns sharp left where it previously passed under the railway line, and then wiggles down hill to the bridge over the River Ugie. A short wiggly climb then brings it up to the C5B, where it ends a short distance west of the A90.
