We're hoping to go to northern Portugal this summer for two weeks. We would likely fly in and out of Porto, and hire a car for the trip. We usually split our holidays into two separate locations, with a week in an Airbnb in both. Happy to do a fair amount of driving, but ideally no more than an hour for day trips.
We have DS13 and DS16. We love castles, museums, river swimming, walking/hiking, history, mountains, remote/quiet beaches, city breaks. Last few holidays have been a combination of a week in the mountains then a week near beaches (Dolomites and Croatia and Slovenia and Croatia) so looking for something similar.
I've got as far as a shortlist of Braga, Guimares, Douro Valley, Geres NP, Coimbra, Serra de Estrella, Aveiro, Arouca Geopark but not much more info.
Can anyone recommend must see sites/towns/activities?
Thanks!
