Porto, set dramatically on the granite bluffs above the Douro River, is among Europe's most romantically dishevelled cities — a place where baroque church towers rise above terracotta rooftops and century-old azulejo tilework lines every alley. Cross the iron Dom Luís I Bridge for sweeping views and descend into Vila Nova de Gaia's atmospheric wine lodges for a tasting of aged tawny port direct from the barrel. Seafood is magnificent: salt cod prepared a hundred ways, barnacles glistening with lemon, and custard tarts still warm from the oven. Spring and early autumn offer the finest conditions.

Régua, gateway to Portugal's vertiginous Douro Valley wine country, sits at the point where the river enters its most dramatic gorge — terraced vineyards climbing impossible slopes on every side, their schist walls a testament to generations of viticultural determination. The Wine Museum in Pinhão's art nouveau azulejo station captures the region's soul, while the great quintas — Ramos Pinto, Croft, Niepoort — open their cellars for intimate tastings of vintage port and luminous dry whites. Harvest season in September and October transforms the valley into a festival of colour and ferment.

Novi Sad — the "Serbian Athens" — unfolds along the left bank of the Danube beneath the commanding walls of the Petrovaradin Fortress, a Habsburg military masterpiece whose underground tunnel labyrinth and hilltop clock tower (with hands reversed, to confuse enemy gunners) make for one of Europe's most unusual fortress visits. The city's elegant pedestrian street, the Zmaj Jovina, is lined with 19th-century Habsburg architecture that rewards a leisurely afternoon, while the Serbian cultural renaissance of the same era left behind museums, galleries, and coffee house traditions that endure today. In July, the EXIT music festival transforms the fortress into one of Europe's most storied outdoor stages. Visit May through September for the finest weather.

Pocinho marks the easternmost navigable point of the Douro River — the terminus of the valley where port wine's history began and where the landscape reaches its most elemental and dramatic expression: near-vertical schist slopes terraced into vineyard stairways, the river running silver between them in the early morning light. The restored rabelo boats that once carried casks of wine downriver are now a romanticised memory, but the valley's working quintas welcome visitors for tastings of the upper Douro's increasingly celebrated unfortified wines. The Douro International Natural Park, bordering Spain, protects rare Egyptian vulture colonies on the surrounding plateau. September through October, during harvest, is the unmissable season.

Barca d'Alva, a remote frontier village at the uppermost navigable point of the Douro River, marks the eastern terminus of Portuguese river cruises where the landscape shifts from terraced port wine vineyards into the austere granite borderlands of Trás-os-Montes. The abandoned azulejo-tiled railway station, the almond orchards cascading to the river's edge, and the silence of the surrounding Côa Valley archaeological park — protecting the world's most important collection of open-air Palaeolithic rock art — make this an unexpectedly rich stopping point. Spring brings almond blossom along every hillside; autumn arrives golden with the vendange harvest. The Spanish city of Salamanca lies an hour's drive east.
