|Route outline (key)|
The C13K starts at the Marywell Junction on the A90 and heads south west along Cookston Road, curving back under the A90 into Portlethen. At a mini roundabout near the station, a spur leads east out to Old Portlethen, whilst the mainline turns south west again, along Bruntland Road. This leads to a staggered crossroads on the A90, with double central reservation gap. The C13K then meanders westwards, passing scattered houses and farms. It crosses the new Fastlink road and then comes to an end on the C5K at Lairhillock, just short of the B979.
