Ride Germany, coast to Alps.

The full west-to-east traverse — Dutch border to Polish border, signed as D-Route 3. From Vreden it crosses the Münsterland '100 Castles' country, climbs the Teutoburg Forest and the Weser Hills, skirts the Harz, then runs the Fläming and Oderbruch plains to Küstrin-Kietz on the Oder. Mostly flat-to-rolling, but the Teutoburg, Weser and Harz add genuine climbs in the middle third. Wikipedia and Radnetz Deutschland both give the German D3 as 960 km, Vreden→Küstrin-Kietz.

The long north-east-to-south-west pilgrim diagonal, signed D-Route 7. From the Danish border on the historic Ochsenweg (Ox Road) it runs through Hamburg and Bremen, the Münsterland castles and the Ruhr's Römer-Lippe-Route, then down the Rhine and the Eifel Water-Castles Route to Charlemagne's Aachen at the Belgian/Dutch corner. Flat-to-gently-rolling in the north, more varied toward the Rhine and the Eifel. EuroVelo grades it Moderate; the section-sum across its nine named German legs is roughly 1,160 km.

The Rhine-then-Main river ride, signed D-Route 5. From the Siebengebirge just south of Bonn it follows the Rheinradweg down through Cologne and Düsseldorf to Mainz, then turns east up the flat Mainradweg through Franconian wine country — Würzburg, Bamberg — to Bischofsgrün near the White Main's source in the Fichtelgebirge. Almost entirely flat river-valley cycleway; a gentle rise only at the very end. The ~660 km is a sourced sum of the Rhine (~160 km) and Main (~500 km) legs — EuroVelo publishes no single German figure.

The shortest German EuroVelo — a flat Saar-valley hop, signed D-Route 5. From the Luxembourg border near Konz, at the Mosel–Saar confluence, the Saar-Radweg follows the river south through Saarland to Saarbrücken near the French border, past the Saarschleife loop. Family-friendly and completely flat the whole 80 km. (EV4, EV5 and EV6 all carry D-Route 5, but on different ground — this is the Saar length.)

Germany's most-ridden river tour — the flat Donauradweg, signed D-Route 6. After a short Rhine and Hohenzollern lead-in from the south-west the route reaches the Danube at Tuttlingen, then runs the river the whole way through Ulm, Ingolstadt, Regensburg and Straubing to Passau, the 'city of three rivers,' at the Austrian border. Generally flat river-valley riding; the lead to the Danube is almost all downhill. About 600 km in Germany, of which the Tuttlingen→Passau Danube run is 565 km.

The Baltic-to-Bohemia diagonal, signed D-Route 11 (Berlin–Copenhagen) then the Elbe Cycle Route (D10). From Rostock on the Baltic it threads the Mecklenburg lakes to Berlin, then follows the Elbe past Dresden's Baroque skyline to the Czech border in the Elbe Sandstone uplands. Flat through the lakes and the Havel and Elbe valleys, with gentle hills toward Saxony — EuroVelo grades it easy-to-moderate, Moderate overall for its ~1,040 km length.

The whole German Baltic coast, signed D-Route 2 (Ostseeküsten-Radweg). From Flensburg's fjord at the Danish border it runs the coast east through Kiel and Fehmarn, the Hanseatic cities of Wismar and Stralsund, Rügen's chalk cliffs, to Usedom on the Polish border. Never far from the shore and largely flat, but long, with rolling cliff and bay sections — EuroVelo grades it easy-to-moderate. The German coast totals roughly 1,150 km.

The flat German North-Sea arc, signed D-Route 1 (Nordseeküsten-Radweg). From Klanxbüll at the Danish border it follows the Wadden-Sea coast and the Halligen, turns up the Elbe into Hamburg and its UNESCO Speicherstadt, then runs Cuxhaven, Bremerhaven and Emden to the Dutch border. Flat marsh-and-dike landscape the whole way, always within sight or hearing of the sea — the wind is the only hill. Roughly 930 km over 14 stages.

The wildest, hilliest German EuroVelo — the former inner-German border, the Grünes Band (Green Belt), with no D-Route number of its own. From the Baltic near Usedom it follows the old border south past the Elbe and the Harz fringe, through the Thuringian uplands and the Bavarian Forest to the Czech border. Rolling-to-hilly throughout and partly gravel, with some still-unsigned sections in Saxony-Anhalt — EuroVelo recommends experienced cyclists. The history is the highlight: Point Alpha, Mödlareuth. About 1,100 km for the German section (the inner-border core runs ~730 km).

Germany's headline river ride and most-certified route, signed D-Route 8 (Rheinradweg). From Lake Constance and the Basel/Swiss corner it follows the Rhine north through Karlsruhe and Speyer to Mainz, then the UNESCO Rhine gorge — Bingen, the Loreley, Koblenz — and on through Bonn, Cologne, Düsseldorf and Duisburg to Emmerich at the Dutch border. Largely flat with excellent infrastructure; the gorge adds scenery, not climbs. EuroVelo-Certified on major sections (re-certified Sept 2025) and roughly 865 km of German Rhine.
