How far inland can Danube shipping go?

How far up the Danube can shipping traffic go?

It depends on the section and the vessel. Seagoing shipping gives way to heavy river traffic and then lighter river or canal craft farther inland.

The river accommodates different scales of traffic along its length. Some reaches take seagoing vessels, while others carry heavy river traffic. Farther inland, lighter river and canal craft continue to move goods. Commercial use therefore extends beyond the reaches accessible to large ships.
