@Marye02, do stay at the Albergue de Peregrinos do Mosteiro de Vairão on the first night out of Porto. For me, it was one of the most relaxing and amazing places.
Click here to see more photos of it (scroll down).
On the second day, in Barcelos there are two churches you may want to explore, the Templo do Senhor Bom Jesus da Cruz and the Igreja Matriz de Barcelos, go to my
day sixteen for more info.
On the next day, the Albergue de São Pedro Fins looks wonderful so if your day would bring you there, I would choose that one.
Plan to spend some time in Valença and Tui. The
castle in Valença is amazing and Tui's cathedral as well. We liked Valença so much, we returned to spend more time there after our Caminho!
There are so many little churches and shrines along the way. Plus there are many sections of Roman roads and Roman bridges. SO MUCH to see. If you go to one of my links, you can see a full documentation of this wonderful and more historic route than the coastal.
Happy planning! Elle
