UNESCO Rhine Gorge & Moselle Castles Guide: KD River Boats, Bacharach, Loreley & Burg Eltz

Which 2-hour stretch of the Rhine has the most castles, why you should sail downstream from Rüdesheim/Bingen to St. Goar or Boppard, and how to combine the Rhine with Burg Eltz and Cochem on the Moselle.

Sail Only the Scenic 65 km UNESCO Gorge (Rüdesheim/Bingen to Koblenz)

Do not take a multi-day boat from Frankfurt or Cologne—90% of the castles cluster along the 65 km Upper Middle Rhine Valley between Rüdesheim/Bingen and Koblenz. The single best segment is sailing downstream (northbound) from Rüdesheim or Bacharach to St. Goar or Boppard (1 hr 40 min to 2 hr 15 min on Köln-Düsseldorfer / KD steamers, €24–€32; 20% discount when showing a valid DB train ticket or German Rail Pass).

Must-Visit Rhine & Moselle Castles

  • Marksburg (Braubach): The only medieval hilltop castle on the Middle Rhine never destroyed in battle (€11 guided tour).
  • Rheinfels Castle (St. Goar): Dramatic fortress ruins directly opposite the Loreley cliff.
  • Burg Eltz (Moselle Hills): Held by the same family for 34 generations since 1157, tucked inside a forested valley near Moselkern/Hatzenport (€14 admission).
