Boating activities in Portugal
If there are enough passengers, boats run up and down the Rio Lima daily in summer, from the pier south of Largo 5 de Outubro. The most common trip takes 45 minutes, but longer excursions, with lunch, are available in midsummer. For details call Portela & Filhos or check at the pier.
Full-day cruises take you up into the heart of port wine country. Most tours head upriver by boat and return by train or bus (or vice versa), and offer a snack and at least one full meal. By far the largest carrier is Douro Azul.
