Coimbra to Porto and then to Santiago?

I walked Porto - Santiago, then Fisterra-Muxia in Apr-May, also Santarem-Porto in Oct. Regarding the Coimbra-Porto stage: it has a suburban feel to it, especially the closer you get to Porto. Yes, cobblestones to remember. If you walk in a group and chat then maybe you won't feel it that much I loved Mealhada though, with the street art, umbrellas and a very good albergue. The more scenic stages are between Golega and Coimbra, if you like nature. Cork farms, a lake near Tomar, eucalyptus forests, hills. Even though the distances are huge, more then 30km to walk every day, I loved walking there. Would probably go back for day hikes in the area if and when in Portugal. Also if you have time walk between Fisterra and Muxia - the most amazing beaches are there. We even decided to break it in two and stayed in Lires in between.

Go to Conimbriga first! Lovely Roman museum, good restaurant...
