Porto Port Wine and Food
Bolhão Market, francesinha sandwiches, Gaia port cellars and Matosinhos seafood, plus a Douro Valley wine-tasting train day.
Built around eating and drinking: explore the restored Bolhão Market and the old cafés on Rua de Santa Catarina, taste port at several cellars in Gaia in a row, and enjoy charcoal-grilled seafood in Matosinhos. On day three, take the Douro Line train to Pinhão to visit a winery and go on a boat trip. The pace is relaxed and suited to couples and friends. Only a few must-see sights are included; there is no attempt to tick off every landmark.
Late September to early October is the Douro harvest season; many winery activities need early booking.
