A small coastal town in Wales, utterly undistinguished apart from its use as one of the main ferry terminals from England to Ireland. Like all ferryport towns, Holyhead has that kind of cheesy, ingratiating seafront atmosphere that attracts disgruntled German tourists ("Why is there no control of the littering in this otherwise attractive town?") and drunk football fans ("Ho-ly-head, Ho-ly-head, live here and you're better off de-ad...")

The official Holyhead website (www.holyhead.org) says:

Holyhead is the largest town on the island of Anglesey and is perhaps known best for being a busy ferry port. However, visitors should also note that the town has a number of interesting attractions and is a bustling shopping and visitors area in its own right.
And just to make you feel safe on your journey across the notoriously rough and possibly radioactive Irish Sea to Dublin:
The maritime museum in Holyhead is well worth a visit where you can learn more about the 100 or so shipwrecks that have taken place in the vicinity

I'm booking my ticket right now.
