Day 1: Koblenz – Boppard – St Goar
Arrival in Koblenz around midday to board the IRIS, with departure shortly after. Arriving the day before is recommended to explore the attractive old town located between the Rhine and Moselle rivers, including an optional cable car ride up to Ehrenbreitstein Fortress for panoramic views. In the afternoon, the ship sails south, and later guests disembark in Boppard for a short introductory bike ride along the Rhine cycle path to St. Goar. Overnight in St. Goar

Day 2: St. Goar – Mainz, 25 mi. (40 km)
The day begins in St. Goar, opposite the legendary Loreley, reached by ferry, bus, and a short walk to a viewpoint overlooking the Rhine’s narrowest and most dramatic stretch. The cycling route then follows the river past castles and vineyards to Rüdesheim am Rhein, a lively wine town with Roman roots, famous for the Drosselgasse and its traditional taverns. Cycling continues to Eltville am Rhein, where the ship is rejoined for an afternoon cruise to Mainz. Overnight in Mainz

Day 3: Mainz – Nierstein – Worms, 29 mi. (46 km)
While breakfast is served, the ship sails to Nierstein, the starting point for today’s ride along the Rhine to Worms, one of the oldest cities in Northern Europe and the former capital of the Burgundian Kingdom. Highlights include its impressive Romanesque cathedral and its rich Jewish heritage from the Middle Ages, recognized by UNESCO alongside Mainz and Speyer. Overnight in Worms

Day 4: Worms – Heidelberg, 22 mi. (35 km)
The route leaves Worms and passes through Mannheim, entering the Neckar Valley and continuing to the charming historic village of Ladenburg. The destination is Heidelberg, famous for its picturesque old town, renowned university, and the dramatic castle overlooking the city from the Königsstuhl, accessible by funicular. Overnight in Heidelberg

Day 5: Heidelberg – Mainz, 34 mi. (55 km)
Today’s ride leads away from the rivers and into the countryside, offering a more varied route with gentle hills, forests, meadows, and traditional German villages far from the main tourist paths. The cycling ends in Gernsheim, where the ship is boarded once again for a relaxing cruise back to Mainz. Overnight in Mainz

Day 6: Mainz – Frankfurt am Main, 25 mi. (40 km)
Cycling continues along well-maintained paths following the Main River toward Frankfurt am Main, one of Germany’s largest and most important cities. Known as a historic trade center and modern financial hub, Frankfurt features a striking skyline shaped by postwar reconstruction and is also home to a renowned riverside museum district and the world-famous Book Fair. Overnight in Frankfurt

Day 7: Frankfurt am Main – Aschaffenburg, 34 mi. (55 km)
The day’s ride first reaches the romantic town of Seligenstadt, known for its winding lanes, half-timbered houses, and impressive basilica, followed by a ferry crossing of the Main River and a pass through Hanau, birthplace of the Brothers Grimm. The ship awaits in Aschaffenburg, where the striking Johannisburg Palace dominates the riverbank as one of the finest Renaissance palace complexes in the region. Overnight in Aschaffenburg
