Getting from Cobh to Cork

There is no public bus service. The train station is in front of you as you berth. Probably the closest ship to train transfer anywhere in the cruising world- trains every half hour, 26 minute journey time- https://www.irishrail.ie/IrishRail/media/Timetable-PDF-s/Heuston-timetables/13_mallow_cobh_midleton.pdf

The fare is 6.90 Euro return, buy at the station. Use any train.

That is interesting to know and explains why I haven't been able to find anything out about any bus service on my visits. Interesting to see about the other service to Carrigtwohill for other which could be useful to some people.

And it's really useful (at least to me) to know that the bus stops at the Passage West ferry.

Thanks for that information.

In 2010, I took that exact route via public bus. It took 20 minutes. There was no hassle.

Sorry I cannot remember the route number. I asked for the route at the Cork bus station.

I needed to get to Cobh to catch a ferry to Swansea, Wales. I struck up a conversation with a local man on the bus who was amazed to meet a guy from Chicago. In the ferry terminal, I also talked with a worker who told me about a trip he had taken to the U.S. in 1971 that included stops in Chicago, the East Coast and Texas.

The Swansea ferry always departed from Ringaskiddy on the opposite side of the bay, not from Cobh where most of the cruise ships now call, so a totally different bus route

Yes, I heard the Swansea ferry from Cobh was discontinued two years after I had taken it.

Yes, sadly it was discontinued, the only overnight ship to Ireland to leave and arrive at civilised times. But it wasn't paying its way and even then was a pretty utilitarian ferry compared to the Irish Ferries and Stena competition to Rosslare- now 13 years on very starkly so. While I like and appreciate the greater comfort of the Stena ships (especially the Scandi chic new superflex boats on the Liverpool and Holyhead routes), the Swansea-Cork line was far more my style.
It was sad when the route was closed.
