Six Bridges Douro River Cruise

The classic fifty-minute Six Bridges cruise glides from the Ribeira quay up and down the Douro, passing beneath all six of Portos landmark bridges while a commentary points out the sights on both banks. It is inexpensive, frequent and a lovely way to see the city from the water. Sit on the open upper deck if the weather allows, aim for a late-afternoon departure for warm light, and hold onto your hat.
