The Innradweg follows the Inn from Maloja in Switzerland to Passau in Germany, crossing Austria along the way. Also known as the Inntal-Radweg, it changes character as the river grows: high Engadin lakes give way to the Tyrolean valley, Bavarian towns and the wetlands of the lower Inn. Marketinggruppe Innradweg provides route and planning information for the journey.
From Maloja through the Engadin
The journey begins in Maloja, close to the Inn's headwaters. The route passes Lake Sils and Lake Silvaplana on its way towards St. Moritz, then continues through the Engadin towards Zuoz and Zernez. Switzerland Tourism describes the upper valley as a landscape of lakes framed by mountain peaks.
Beyond Zernez, the valley narrows and the river becomes wilder. The route passes Susch and Lavin before climbing towards Guarda; Ardez, Ftan and Scuol follow on the way towards Martina and the Austrian border. The general loss of altitude does not remove the need to climb: the Swiss section includes demanding rises.
Tyrol and the Bavarian foothills
In Tyrol, the Innradweg follows the broad valley through Landeck and Innsbruck towards Kufstein. Mountains remain a prominent backdrop, while the route connects a succession of towns along the river. Around Kiefersfelden it reaches Bavaria and the Alpine foothills.
Rosenheim and Wasserburg am Inn offer contrasting stops on the Bavarian section. The route information highlights Wasserburg's position within a loop of the Inn and the distinctive Inn-Salzach architecture found in towns farther downstream. Chiemsee-Alpenland Tourismus presents eastern and western variants between the Kufstein area and Wasserburg, making the choice of riverbank part of the planning.
The lower Inn and Passau
Downstream, the route reaches the Europareservat Unterer Inn, a cross-border protected landscape of water, islands and mudflats. Tourismus Passauer Land describes a western variant from Ering through Malching, Würding and Gögging to Neuhaus am Inn. The old Inn bridge there connects with the Baroque town of Schärding in Austria.
From Ering, crossings allow riders to consider Bavarian or Austrian riverside options. On the Bavarian side, the route continues past the Vornbacher Enge and Neuburg am Inn, then through the Neuburger Wald to Passau. The journey ends where the Inn meets the Danube; the Danube Cycle Path offers an onward connection.
Planning the ride
The route group stresses that the Innradweg is a cycling route rather than a fully separate cycle path: some sections share minor roads with motor traffic. It also notes longer gravel sections in Bavaria that are unsuitable for road bikes. Expect some climbs and hilly stretches even when travelling downstream.
The route website offers an interactive stage planner and information about reported closures and diversions. Check these alongside local conditions before setting out: Switzerland Tourism warns that sections can be interrupted by weather or the season. The route group recommends carrying warm clothing because Alpine weather can change quickly, and says travellers should carry a travel document for the three-country journey.
