think it was running as it was November and Polruan was honestly like a ghost town! But to our luck it turned up just as we were about to leave. The ferry does run every 15 minutes from 10-5 on a Sunday even in the winter. You might just have to be a bit patient which we were not! I will leave a link here to the ferry’s timetable. It cost us £2.20 each to catch the 5 minute ferry across to Fowey.
Polruan
As mentioned above Polruan unfortunately, in the winter is a bit of a ghost town. Most of the homes are holiday homes with all of the curtains drawn. However, this does mean that it is lovely and quiet and you can find a parking space!
