Hello - we are traveling to Dublin in November and are thinking of doing a day trip on the ferry (on foot, no car) from Dublin to Holyhead. Does anyone have any suggestions for a (very quick!) day trip in the Holyhead area? We should arrive around 10 am and have to be back to check in for the ferry @ 4:45 pm. Thank you! Would most likely be looking at public transportation options in Holyhead, unless it's reasonable to do cabs.
