The Oberschwaben-Allgäu-Radweg is a roughly 365-kilometre circuit between the Danube and the Lake Constance region. Presented by Oberschwaben Tourismus, it connects historic towns and monasteries with rolling countryside, protected wetlands and views towards the Alps.
From Ulm into the Allgäu
Oberschwaben Tourismus describes the circuit clockwise from Ulm. Its first stage passes through Laupheim to Ochsenhausen, where a former monastery announces the arrival in a landscape rich in religious and architectural heritage.
From Ochsenhausen, the itinerary heads towards Bad Wurzach and Leutkirch im Allgäu. Woodland and meadows frame this part of the journey, while Leutkirch offers cobbled lanes and historic houses. The next section continues via Isny and Argenbühl to Wangen im Allgäu.
Towards Lake Constance and north again
From Wangen, the route goes through Tettnang to Markdorf. The regional guide describes views towards Lake Constance and the Alpine chain on this southern part of the circuit. Tettnang’s New Palace is one of the historic buildings highlighted by Germany’s national tourism organisation.
Beyond Markdorf, the route turns north towards Aulendorf. The following stage goes through Bad Schussenried and Bad Saulgau to Bad Buchau. In Bad Schussenried, the former Premonstratensian monastery and its ornate library hall offer a cultural stop.
Wetlands and the return to the Danube
Near Bad Buchau, the route reaches the Federsee nature reserve. Germany Travel points to birdwatching in the area and to prehistoric pile-dwelling settlements associated with the UNESCO World Heritage site. Allow time for a stop if the region’s wetland landscape is a priority.
The circuit then heads towards the Bussen before turning east through the area of Oberstadion and on to Ehingen. The final section returns to Ulm, with views over the Danube valley on the way.
Planning the circuit
The tourism organisation divides the route into eight suggested stages, but also states that it is signposted in both directions. Its route page provides a detailed itinerary and lists cyclist-friendly accommodation. A regional cycling guide is available to order and includes maps, route information and an accommodation directory.
Expect some hills as well as more relaxed sections. Germany Travel describes the route as mostly paved, with some unsealed sections, and predominantly free of motor traffic. Lakes, thermal baths and outdoor pools provide possible breaks on many stages; check the individual facilities when arranging a stop.
