The River Po: Italy’s Longest River

The Po River is the longest river in Italy, flowing eastward across the northern region of the country. It stretches 405 miles (652 km) from its mountain origin to the sea.

The river’s vast drainage basin covers roughly 27% of Italy’s national territory, creating the Pianura Padana (Po Valley)—the widest, most populated, and most fertile agricultural plain in the country.

The Po River rises from an alpine spring at Pian del Re, a flat plateau directly under the northwest face of Monviso (Cottian Alps) near the French border.

It flows into the Adriatic Sea (just south of Venice) via a massive, ecologically rich delta that spans 380 square kilometres and splits into at least 14 distinct mouths.

The river flows through four major Italian administrative regions: Piedmont, Lombardy, Emilia-Romagna, and Veneto.

It passes directly through Turin, Piacenza, Cremona, and Ferrara. It connects indirectly to Milan through a historic network of canals (navigli) designed with the help of Leonardo da Vinci.

The Po Valley is Italy’s economic powerhouse, supporting 16 million people. It produces much of Europe’s rice exports, wheat, and dairy.

In recent years, lower Alpine snowfall and climbing summer temperatures have triggered severe droughts along the Po. This causes seawater to creep back into the delta and threatens the irrigation of regional rice paddies.

The river is navigable for commercial and cruise vessels from its mouth at the Adriatic up to the city of Pavia. The Po Delta is designated as a UNESCO World Heritage Site, famed for its exceptional birdwatching, lagoon clam-fishing industries, and cycling paths.
