You cannot leave Porto without a port wine tasting in Vila Nova de Gaia. This district, also known as Gaia, is home to the terracotta-topped port houses that store most of the world’s supply of Port. Enjoy the ambiance from one of the cafes and restaurants at the riverfront or make a boat trip on a "Rabelo" - a ship that was used to transport the port barrels on the river Douro.

Tip: Come here in the late afternoon and stay for dinner at the river front while you are enjoying the view over the Douro river.
