Porto and the Douro Valley have it all: a bohemian arts and music scene, world-class museums, fantastic architecture, a foodie renaissance, wine tasting in spectacular scenery . . . the list goes on and on. Best of all, it's affordable. This is a great value destination for those interested in food, the arts, history, and culture. Use the vibrant city of Porto as a base, and take day trips (and river cruises!) to the birthplace of port wine.
