Jeff, welcome on the forum. Just what you prefer ! The Portugese is more road walking but very doable besides that there are more Portugese caminhos.
The coastal, the central and the internal.All different.
I walked the Caminho Português central all away from Lisbon, walked the Inglès from Ferrol and start next tuesday the caminho Português coastal from Porto.
What my wife and I like is the friendly contacts with the Portugese people, we love their food and wines. The landscape We love Portugal.
But if you ever should start in Tui, you hardly will meet them because from there you'll walk in Spain-Galicia .also very kind people but a different atmosphere. What I liked too. I used to work for some years in Spain .
But we love the camino in common and the complete atmosphere with a laugh and a tear..
Read back a bit back on the Ingles forum and on the Portugese, I advise you.
And you are kindly invited to follow my travelblog which starts next tuesday (if wifi is available in the first albergue in Vairão near Porto ) the language will not be a problem. Our blog is in English and Dutch.
