Lisbon is the obvious choice for an affordable weekend in Portugal, but the country’s second city is just as appealing. Known for its eclectic neighbourhoods, riverside restaurants and world-famous fortified wine, Porto was made for a later summer break. Over the last 15 years, it’s undergone a massive renovation, but its cobbled streets are still lined with artisan shops and cafés, filled with locals drinking coffee, snacking on pastéis de nata and eating great seafood cooked on the street. Split by an iconic metal bridge across the Douro, the cityscape is a sophisticated one, with rows of granite buildings and balconied houses interspersed with charming markets, museums and gardens. Porto is ideal for pottering around and taking in the sights, as well as tasting its most famous export at one of the many port houses. When you’ve drunk your fill of sticky red ports, a white port and tonic is a refreshing alternative.
