There are no ferries from Northern Ireland to France. To get to France by ferry you would first drive to somewhere in the Republic of Ireland, particularly Rosslare, and get a ferry from there. The ferry takes about 24 hours, and the drive to Rosslare from Northern Ireland would take at least 3 hours, depending on where in Northern Ireland you were starting from.
