Long overlooked in favor of its larger neighbor, Spain, Portugal is holding its own on the European travel circuit today, as growing numbers of visitors discover its old-world charms. Outstanding food, award-winning wines, and distinctive Manueline architecture are just the beginning. Portugal's diverse landscapes range from granite peaks and forested hills in the north, to the sunny beaches of the southern Algarve—all bordered by nearly 500 miles of stunning Atlantic coastline. Start in Lisbon, taking in the capital's many historical sights and famous hills by foot or electric bike. The country's faded glory as a maritime empire in the 15th and 16th centuries is most evident here, but humans have lived in this region since prehistoric times. After a city tour, take a day trip to wander through Roman ruins in Evora; tour a royal castle and a Moorish palace in Sintra; or visit one of the well-preserved medieval villages, like Obidos, that are sprinkled all over the countryside. In Northern Portugal, foodies flock to the UNESCO-listed Douro Valley for wine- and food-tasting tours. Porto's striking harbor is the starting point for scenic Douro River cruises. Thrill-seekers can get their adrenaline fix by surfing, skydiving, or parasailing in the Algarve. And for those who prefer a more relaxed pace, the fishing villages of Nazare, Sagres, and Tavira can feel like a trip back in time. Portugal's delights are many, and with easy access to Western Spain, your Iberian itinerary could extend to Seville, Cordoba, or Granada.
