Locks on the Rhine: Amsterdam to Basel

The Rhine is navigable from the North Sea (Rotterdam/Amsterdam) to Basel, Switzerland—approximately 1,030 km (640 mi). This commercial waterway includes over 150 locks managing elevation changes, especially through the Rhine Gorge and the Upper Rhine canalized sections.

Key Stretches & Lock Counts (Approximate)

• Lower Rhine (NL/DE border → Bonn): ~5 locks (IJsselkop, Hagestein, Amerongen, Driel, Volkerak – some on branches)
• Middle Rhine (Bonn → Bingen): Free-flowing, no locks (UNESCO gorge).
• Upper Rhine (Bingen → Basel): Canalized (Grand Canal d'Alsace + old Rhine). ~10–12 major locks (e.g., Strasbourg, Gerstheim, Rhinau, Marckolsheim, Vogelgrün, Fessenheim, Ottmarsheim, Kembs, Huningue/Basel).
• Tributaries/Canals (Main-Danube, Moselle, Neckar): Add 50+ more locks if continuing beyond Rhine main stem.

The "150+" figure likely includes all locks on the Rhine–Main–Danube corridor (North Sea to Black Sea, ~3,500 km), not just Amsterdam–Basel. For the direct Rhine route to Basel, expect 15–20 operational locks on the main stem + canal sections.
