The offer is on all sailings from the UK to Ireland and return, for travel between 1 September and 18 December this year.
“Autumn is a fantastic time to put your car on the ferry to discover the historic landmarks of Ireland’s Ancient East or the Wild Atlantic Way in the west,” says head of passenger sales Dermot Merrigan.
The discount also applies to autumn sailings on the Dublin Swift, the only fast-craft on the Irish Sea, which crosses between Holyhead and Dublin is as little as 1 hour 49 minutes.
