Just inside the 'new' harbour at Holyhead port.
The Port of Holyhead (Welsh: Porthladd Caergybi) is a ferry port in Anglesey, Wales, handling more than 2 million passengers each year. Stena Line and Irish Ferries sail from Holyhead to Dublin and Dún Laoghaire in Ireland, forming the principal link for surface transport from north Wales and central and northern England to Ireland. The port is partly on Holy Island and partly on Salt Island (Welsh: Ynys Halen).
There is access to the port via a building shared with Holyhead railway station, which is served by the North Wales Coast Line to Chester and London Euston. The walk between trains and ferry check in is less than two minutes, but longer from the remote platform 1, used by Virgin Trains. The port is accessible to motor vehicles via both the A5 and the A55 roads. Pedestrian access from Holyhead town centre is via The Celtic Gateway, a bridge linking town and port, and takes about five minutes. The largest ferries arrive and depart from the 300-metre Admiralty Pier.
