Douro, Porto and Salamanca River Cruise.

July–September 2026 departures · from $2,699 per person. Seven nights from Porto into the terraced heart of the Douro Valley: sail a river tamed into a chain of glassy lakes, past olive groves, vineyards, and medieval villages stacked on the hilltops. From the valley's upper reaches, cross into Spain for a day in golden Salamanca — one of Europe's oldest universities and its most beautiful plaza. Port tastings, quintas, and five-star comfort throughout — the trip that feels like months away.
