Hello sorry about this.
There is conflicting information as to whether there is parking available at the port of Roscoff for passengers leaving to go to other shores. Now Brittany Ferries UK says not. Apparently there is a sign (or was) saying that as from 1st of August parking was only allowed for 48 hours and on asking Brittany Ferries.fr you are told that when you arrive at port present your ticket for ferry and you will be charged for parking upon your return. Also Roscoff port authorities say this is so. I am wondering if the confusion has occurred as the lack of parking after 48 hours may just refer to the parking close to the terminal rather than further out in the large parking area.
If anyone has very recent experience could they let me know.
