We have 10 nights from Porto to Lisbon and need help deciding what to do between them. We will pick up a car after Porto and drop it off when getting to Lisbon.
2 night Porto
1 night Douro Valley
4 nights ??
3 nights Lisbon with a day trip to Sintra or take a night from the 4 and spend it in Sintra?
We like leisurely hiking, wine, history, and small towns.
Coimbra and Tomar come to mind. It depends on what you like visiting.
