What to do in September
The Douro is the priority: a day with tasting, lunch at a quinta and a cruise is the most booked outing from Porto; see which trip to choose, or stay there (sleeping in the Douro Valley) to see the vines early in the morning. The exact harvest dates change every year: ask the quinta whether grapes are being picked on the day of your visit. In Porto, terraces remain pleasant: Ribeira, six bridges cruise, Gaia cellars. The Foz and Matosinhos beaches remain usable.
Events of the month
- Grape harvest: in the Douro, from late August to October depending on the year.
- Public holidays: none in September.
