Lisbon has inspired explorers for centuries with its stunning setting at the Tagus River's mouth. Its labyrinthine streets carry echoes of 16th-century navigators who sailed on the winds of the Age of Discovery. The city prospered greatly from its trade. And today's streets are lined with the legacies of wealthy builders, including the Jerónimos Monastery and Belém Tower, stunning works that introduced Manueline architecture. Savoring local cuisine and port wine are favorite pastimes here. On any evening, the strains of fadospill from clubs in the historic Alfama District.

Throughout Lisbon, fascinating monuments tell this proud city's story. Along the riverfront, in Praça do Comércio, an equestrian statue at its center represents Portugal's King José I, who capably rebuilt the city following the devastating 1755 earthquake. Among the most recognized of Lisbon's monuments is the grand Monument to the Discoveries on the banks of the Tagus River, displaying statues of more than 30 contributors to exploration, whose bravery and spirit still shape the culture of this vibrant European capital.

Porto holds a place of great traditional importance. The town lends its name to the port wine produced in the region and throughout the nation. Located along a rocky embankment, the city boasts picturesque neighborhoods, fashionable restaurants and lively markets. Like Lisbon, Porto has a rich past; its historic center is a UNESCO World Heritage Site of narrow cobblestone streets brimming with romantic buildings spanning the centuries and a Romanesque cathedral. At the riverside, small barcos rabelos, boats once used to transport casks of wine, paint a charming scene.

The sleepy town of Pinhão is situated between the Douro and Pinhão Rivers, in the epicenter of the valley's port wine-making region. The climate and growing conditions here are perfect for port grapes and the surrounding landscape, festooned with vineyards, creates a serene experience. The biggest names in port have quintas, or wine estates, nearby. During the annual grape harvest in autumn, the village comes to life, attracting workers and wine enthusiasts from across the whole of Europe.

Journey through the Douro River valley into the history of fine Portuguese wine. Surrounded by terraced hills, spot some of the area’s quintas, or wine estates, clinging to the slopes, nestled snugly among their vines. In this beautiful and largely unspoiled region, olive and almond groves share the river’s banks with vineyards. And it is hard to ignore the fact that this journey follows in the wake of traditional barcos rabelos that once transported wine downriver to the waiting casks in Vila Nova de Gaia.

Founded by a Celtic tribe before the rise of the Roman Empire, Salamanca was named a UNESCO World Heritage Site in 1988 due to its beautifully preserved buildings. It is home to one of Europe's oldest universities, founded in 1134, and its main square, bustling with students, is often called the most beautiful in Spain. The beauty of this richly historic city, besides the enormous Romanesque cathedral whose profile dominates the town, is the grace with which Salamanca retains a traditional Spanish village feel. It is a living museum that takes visitors back to the Middle Ages.

Pinhão is surrounded by picture-postcard terraced hillsides that are synonymous with the Douro River Valley. Its slow pace and quiet atmosphere belie the fact that it produces world-renowned port wines; some of the most recognizable names in port production operate wine estates near here. One of the “station towns” along the Douro River, Pinhão boasts a relaxing and scenic promenade along the river, perfect for strolling and drinking in the beauty of vineyard-clad hills. The village’s railway station is decorated with 24 spectacular scenes depicted in azulejos, Portugal’s distinctive blue-and-white tiles.

The magnificent 19th-century Luís I Bridge, designed by a disciple of Gustave Eiffel and opened in 1886, spans the Douro River to link Porto to Vila Nova de Gaia. Known locally as "Gaia,” the city is central to Porto's role as a major producer of port. Here, amid ceramic, glass and soap factories, cellars of 58 companies fortify the prized wine. Visiting Gaia offers insight into how Douro River valley wines are transformed into some of the most sought-after ports in the world, and provides panoramic views of Porto, as many of the cellars are located on the banks of the river.

Porto's prosperous future was sealed when the distinctive, single-masted barcos rabelos delivered the first wine shipments here from vineyards up the Douro River. Before the advent of the railroad, these wooden cargo boats provided the fastest and most efficient transport of wines between the Douro River valley's wineries and the city, from which bottles were exported all over the world. Today, the vessels are owned by port wine companies along the Douro. Though no longer in use, they still grace the river's edge nonetheless, enriching the city's character and cultural identity.
