Porto packs a lot into one small city, and this easy full-day tour shows you the best bits without rushing. You’ll wander the UNESCO-listed Old Town with a guide who actually knows the stories behind the colorful tiles and baroque churches. A stop at a classic wine cellar means tasting real port in the place it was born. Lunch is on your own so you can pick whatever spot catches your eye. The highlight for most people is the relaxed one-hour cruise down the Douro – six famous bridges slide by while the riverside neighborhoods glow in the sun.
