We had not a drop of rain the whole time. In fact some of the days had not a cloud in the sky. Did you go to Palacio de Pena in Sintra?
It rained every single day of our trip. Heavy winds at night, too. We had arranged transportation up to the palace, but the vans never showed up. There was one person in our party who couldn't have made the walk up, so we skipped it. Sintra was lovely, though. But the coolest part was driving the backroads through the Portuguese countryside.
