Porto is the secret capital and namesake of Portugal. The small port city is often overshadowed by Lisbon. This makes hip Porto, with its melancholy streetcars and fine sandy beaches, a real insider tip. Porto's hotels entice visitors with the sight of the colorful houses in the old town district of Ribeira, some of which are decorated with blue-and-white azulejos. Visitors taste their way through the wine culture of the Duoro Valley, home of Port wine, in trendy wine bars along the harbor.
