MV Argyll Flyer

A Clyde passenger ferry seen here on its return from Dunoon at the Gourock quayside adjacent to Caledonian Macbrayne headquarters ... passengers can walk onto the railway platform behind to access the Greenock/ Paisley /Glasgow train. Those with vehicles for Dunoon must use the frequent unbooked Western Ferries crossing a short distance west at McInroys Point
After lockdown disruption ferries are running a full service.
People using Calmac ferries to access popular Scottish islands should however check their website and new timetables and must book to avoid disappointment
