This small river port is a working town, and though not as scenic as its smaller neighbor Pinhao, it's the true heart of port-wine country, and all the wine from the vineyards of the Upper Douro Valley passes through it on its way to Porto. Local wine lodges offer tours of their cellars, which make a nice contrast to the large-scale operations in Vila Nova de Gaia. The Museu do Douro provides a showcase for the wine-making
industry. Many boat tours from Porto end in Régua (the town's shortened name); others pause here before continuing upriver to Pinhão, whose train station is lined with beautiful tile panels.
