Portugal is one of the best-value countries in Western Europe. Lisbon and Porto are the two city anchors, both walkable, affordable, and rich in food and history. The Algarve in the south has the beaches; the Douro Valley in the north has the wine country; and the country is small enough that internal drives are short.
The food is simple and excellent: grilled fish, salt cod (bacalhau) in a hundred preparations, pastéis de nata (custard tarts), and port wine. Portugal's seafood is among the best in Europe, and the prices are noticeably lower than Spain, France, or Italy.
The weather is mild year-round — Lisbon is warm enough for outdoor dining from April to November. This makes Portugal one of the best shoulder-season destinations in Europe: go in May, September, or October for warm weather, empty beaches, and lower prices.
Portugal suits couples, families, food lovers, and first-time Europe travelers. It is one of the easiest countries to travel in: English is widely spoken, distances are short, and the cost is low.
