The C17 starts on the B788 and runs east through Strathgryffe, along Auchentiber Road above the Gryfe Water to a junction with the C37 near Auchenbothie. Just before the end, the road passes under an old railway track, now a busy cycle route.
The road is narrow, undulating and meandering for its entire length. Fenced on both sides, it runs through farmland, consisting mostly of sheep and cattle pasture.
The unmetalled Devol Road branches off to the left, crossing Devol Moor on the way to Port Glasgow. The first few hundred metres of this road were improved around 2015 to enable the construction of wind turbines on Devol Moor.
Further along on the right, another unmetalled road branches off at High Mathernock farm. This leads to a former WWII heavy artillery battery and continues to the B788 at Chapel Farm.
Further along on the right, Gryffeside Road branches off to also eventually reach the B788 at Mountblow.
The end of the road is reached immediately after passing under an old railway arch, which is on the former St Enoch to Princes Pier line, this section of which closed in 1966. THe line is now part of National Cycle Network Route 75.
