Best Time to Take a Douro River Cruise (Portugal & Spain)
Considered one of the most untamed rivers of Europe, the Douro, stretching from the Atlantic Coast of Portugal into the Iberian heart of Spain, enjoys a longer cruising season than most European rivers due to its relatively southern location on the continent. More months of warm weather and milder winters allow Douro River cruise operators to start in March and run cruises through late November.
