Its a cracking track surface
BUT there is one section to avoid in Port Glasgow, as it can be seriously littered in broken glass. The council lads do their best though.
I've never been further east past Hunterhill but from there you join the track and meet the main track just before Canal Street Station, Paisley.
Its signposted no problem but there is a short road section at Elderslie but the track starts just after the traffic lights past the Nisa shop which is on your left coming from the east,you will see a car wash ahead on your right and the track starts just before it...
A right hand turn at the junction with the pencils statue thing (signposted) and it is track until Kilmacolm where a short quiet road section heads west, stop at the Pullman Bar and look for the sign at the edge of the car park which takes through a very short pavement, turn right at the junction and the track starts again at the end to your right.
Carry on to Port Glasgow, you go under a low stone bridge and come to a path junction, head left where you climb a short rise.
The track turns to road, you head left and quickly downhill. The foot of this hill you will see the cycle track signs for crossing the road..
If you want to avoid the normally broken glass sections..
Turn left and head west, you will see factories to your right and at the very last factory(Sangamo), take a right turn and take your time going downhill and about 200 m from the top of the hill you will see the cycle track kinda sharply on your left..
Carry on, you drop down over a metal bridge and head up a sharp rise, carry on until you reach a park area..
This is where it turns to local roads and just follow the signs, at lower level in Greenock , a few shared footpaths.
If you decide to travel the glassy section, make sure you have Marathon Plus tyres.
I'd be careful at night travelling this route..just a heads up.
I stay in Port Glasgow so any other assistance on scenic diverts through any of cracking back roads we have..
Let me know either through this thread of by message.
