I'm arriving by train to Bangor in the afternoon in April and see there is a bus to Chateau Rhianfa that I can take, or a taxi if necessary. When I leave Chateau Rhianfa, I wanted to go via the Llanfairpwll train station. Is it easy enough by bus (morning departure) or should I take a taxi? I"ll have a train ticket (rail/sail to Dublin), is there anything special I need to do to flag down the train to make sure it stops? Also, How best to go from Chateau Rhianfa to Garth Pier if I wanted to go by bus (or is a taxi better) to snap some photos there? thanks!
