The question was asked a few days ago in the forum.
Having walked the Camino Frances in 2017, the same group of us are planning to walk the Camino Portugues starting in Lisbon in third quarter 2019. From Porto, we are trying to decide whether to take the internal route, or alternatively walk the coastal route (Porto/Vila do Conde/Esposende/Viana do Castelo/Caminha) re-joining the internal route at Tui. I am sure both routes have their attractions but has anyone walked both and can advise which they preferred? I did see a YouTube video of a group walking from Ponte de Lima to Rubiaes past the cruz dos Franceses and that looked really scenic.
Read all the good advice given on Coastal route from Porto or the internal route? here on the forum.
