|Route outline (key)|
The C18K starts on the A937 to the south of Marykirk, and very close to the council boundary, which follows the River North Esk. The route runs south east, following the north side of the river, albeit climbing a little before turning back at Morphie to reach the riverbank. Diverging once more, the C18K climbs another hill to reach the A92 above the well known old railway viaduct at Lower North Water Bridge.
