We love to visit more than one country when we travel to Europe. Here are the Google lists for the places we've been:

Barcelona

Lisbon

Copenhagen

Amsterdam

Berlin

Munich

Ireland

Paris

We highly recommend doing a walking tour during your visit to Porto, or any European city for that matter. Sandeman's offers free guided tours in most major cities across Europe. Tours typically last around 3 hours, with breaks included. The tour guides work on tips, and it is customary to tip around €10 per person.

Exploring the city through a free walking tour is not only a great way to learn about its history and culture but also an excellent way to get personalized recommendations for food and beverage from a local. We like to do walking tours early in our trip so we have the lay of the land.

Hop aboard a typical Douro boat and discover the only city in Europe containing 6 bridges. Navigate past the historic center of Porto, Vila Nova de Gaia, and the mouth of the Douro River.
