This route links Kilmacolm to the Erskine Bridge via Bishopton. It can be accessed using the Sustrans route between Paisley and Greenock, which passes through Kilmacolm. Indeed this route can be used as part of a circuit taking in either Glasgow or Renfrew, Paisley, Kilmacolm, Old Kilpatrick and Paisley.
Starting from the Pullman pub located in the old station building at Kilmacolm, head up Station Road to the B786 Lochwinnoch Road. Turn right then left across this road to go into Duchal Road, proceeding cautiously due to the poor sightlines. Follow this suburban road until it merges with Gryffe Road, then take the next road on the left, Houston Road. Take this road straight on across the main A761 Bridge of Weir Road, and continue up this road, which becomes Kilallan Road, leaving the village and passing a golf course.
Once past the golf course turn left at a right-hand bend onto a poorly surfaced road, Corsliehill Road. At the far end of the road, turn left onto the B789 Barochan Road. Take the second right turn, which is located at Formakin, an awkward turn at the foot of a steep descent, for Bishopton.
Climb again out of Formakin on the minor road, then turn right at the cross roads to descend into Bishopton. Cross the main A8 Greenock Road and fork left into Old Greenock Road. Go straight on at the next junction across the main B815 Ferry Road, and continue right through the village. Turn left immediately after crossing the motorway bridge, onto a country lane, Drumcross Road. At the end, turn right onto the B815 Ferry Road, to head towards the Erskine Bridge. To take the cycle track across the cable-stayed bridge go straight on at the roundabout just before the bridge, then left onto a path at the beginning of a bus layby. There is no dropped kerb at this point. Climb steeply up to the bridge to join the main cycle track. Alternatively you can go through the toll plaza by taking a right at the same roundabout to following the loop road round and climb more gradually up to the bridge. Keep to the left if you choose this option.
If you wish to go to Erskine town itself, or to continue to Inchinnan or even Renfrew, go straight on at the B815 cross roads in Bishopton, along Old Greenock Road to Erskine. Cross straight over the A726 roundabout and one other roundabout in Erskine, then turn right through the bus gate, to get to Inchinnan. Continue straight on through Inchinnan to join the main A8 for a mile before arriving at the lifting bridge on the edge of Renfrew.
