Rhine, Moselle, Saar & Heidelberg
A grand self-drive loop starting from Frankfurt, winding along the Rhine, Moselle, and Saar rivers to Heidelberg.
Connect the scenic river valleys and World Heritage sites of Western Germany: Mainz, the Rhine Gorge, Eltz Castle, Cochem, Trier, the Völklingen Ironworks, Speyer, and Heidelberg. Daily driving distances are short, but the route features many winding mountain roads and ferry crossings. Ideal for licensed drivers and second-time visitors looking for charming towns and panoramic viewpoints. Cologne and the Ruhr region are not included in this loop.
Eltz Castle is open from early April to early November; the wine region can be quite warm in mid-summer.
