Flowing over 1,000 kilometers, it runs from the Carpathian Mountains to the Baltic Sea, serving as a vital waterway for transportation and trade. Other notable rivers include the Odra, which forms part of the border with Germany, and the Warta, a tributary of the Odra. These rivers play a crucial role in Poland's ecosystem and economy. They provide habitats for various wildlife and support agriculture through irrigation. Additionally, rivers like the San and Bug are popular for recreational activities, including fishing and kayaking.
