Here are all the different ways of travelling out of or onto our island without flying (or sailing yourself of course)……

Irish Ferries routes
P&O Ferry routes

DFDS ferry routes

Stena ferry routes
Brittany Ferries routes
Steam Packet ferry routes

The shortest ferry routes are between Belfast or Larne and Cairnryan.  The most frequent and best connected ferry route for onward travel, in either direction, is Dublin to Holyhead.  The ferries to Britain tend to operate several times per day, and the ferries to Spain and France a few times a week.

There are also irregular ferries from Dublin and Belfast to Isle of Man, and regular ferries from Isle of Man on to Heysham or Liverpool, so going to Britain via Isle of Man may be possible at some times of year. These ferries are run by www.steam-packet.com.

The frequencies in the above table were worked out mostly for June/July 2025 from the various websites, assuming the passenger is a foot passenger or cyclist, except for the Rosslare-Dunkirk route, which very strangely allows pedal cyclists (and motorised vehicles) but not foot passengers (so you’d have to find a bike to bring??).  People travelling by motorised transport sometimes have more and better timetable options and price offer options from the ferry companies than foot passengers or cyclists (not less, as you might expect) – see the campaigns page for more on changing this!

Booking a ferry

You can book on the ferry company website directly.  Here are the websites of the ferry companies:

From Darach: There are also third party booking platforms such as directferries.com – handy for figuring out ferry routes around Europe and the companies that serve them. Sometimes you get a cheaper ticket by booking with them.

Booking earlier or later on ferries generally doesn’t make it cheaper or more expensive, but they can get booked out, so book early for best choice of timetable.

For longer or overnight ferry trips, you may like to book a cabin or a reclining seat. Some cabins have sea views and some do not.

Before you book the ferry consider whether you would like to combine the ferry with train or bus travel.
