What is the best way to get from ferry terminal coming from Dublin to the two or three best north wales castles? I would think bus or train? Any B and B recommendations for those on a budget? Perhaps three nights in the area and then train to London. Any thoughts would be great.
The Castles in Northern Wales are a distance apart and not very convenient to public transportation. If you can not rent a car for the 3 days, maybe there is a small tour company...hopefully others will let you know. Then take the train to London. All levels of B & Bs are available...just check with the local Tourist Info Office. We stayed on a sheep farm on Anglessy and went to Beaumaris Castle from there.
I took the train to Bangor, and made that my base. From there, I took buses to Caernarfon, Beaumaris, Conwy, and Llanberis. Loved it, can't wait to go back. Edited to add... Public transport was cheap, easy, and convenient. I wanted to go to Harlech, but found it more complicated, but all the above were done with ease.
we also made Bangor our base and bought a bus pass... went to all the places JumpinBug mentioned as well as a day in Snowdonia. Bus pass was inexpensive and convenient.
