Getting to Baiona from Porto

Bus to Vigo (ALSA or ASTA), then local bus to Baiona. The bus companies are from memory.
Or, splash the cash and hire a taxi!

bus in Porto to Vigo
• bus company AUTNA (yellow bus), they have a couple of stops. I took it at Rua Campo dos Mártires da Pátria. They have a convenient 10h15 line (but they can be late depending on traffic). You can buy the tickets in advance at the coffee place in front. Lovely Brazilian waiter, very helpful and speaks English

bus Vigo to Baiona
• in Vigo station, bus company ATSA, downstairs, stops 9, 10, 11 and 12. I took the 15h30 bus. You can get the timetable on the tourist information but the person there did not speak English. I've posted the timetable in another post, can't find it now
