Beaumaris Castle in the town of Beaumaris on the Northeast coast of the Isle of Anglesey in Northwest Wales
From Bangor, several buses (53,57,58) travel to Beaumaris in about 40 minutes. This is one of Edward I's castles
and it has a moat around it. The town is quaint, and the castle is worth the trip for the view from the outside, but probably not worth the entry price (£3).
