Map bike tour through the Danube valley

Day 1: Individual arrival in Donaueschingen

Welcome to the royal seat of Donaueschingen! Your bike tour through the Danube Valley begins at the very point where the Danube embarks on its journey towards the Black Sea. A must-see is the heart of Donaueschingen itself – the renowned source of the Danube. Situated within the castle grounds, between the town church and Fürstenberg Castle, this historic site marks the river's birthplace. The water that emerges here is rainwater from the Black Forest, which gradually seeps into the earth, travels underground to the edge of the forest, and finally resurfaces in Donaueschingen as the Danube’s iconic source.

Day 2: Donaueschingen – Tuttlingen, approx. 35 km

Toss a coin over your shoulder into the source of the Danube. Legend has it that this gesture will ensure your return to Donaueschingen. With that done, it's time to set off on your cycling adventure! You’ll begin your journey along the Danube Cycle Path, heading towards Immendingen. This first leg is a gentle ride, providing a relaxed start to your exploration of the Danube Valley.
Not far from Immendingen, you’ll encounter the Danube sinkhole – a fascinating natural phenomenon. Continuing along the path, you’ll cycle through picturesque river landscapes to Tuttlingen, where you’ll spend the night.

Prepare for a day filled with natural grandeur as you journey through the heart of the Danube Gorge. The river winds its way through imposing, steep cliffs of rugged white limestone, creating a dramatic and awe-inspiring landscape.
In Sigmaringen, you’ll be greeted by the magnificent Hohenzollern Castle, one of Germany’s largest city castles. Dating back to the 11th century, this historic fortress offers a fascinating glimpse into both the architectural splendor of the building and the storied history of the Hohenzollern family. A visit to the castle will allow you to explore its opulent interiors, the impressive armory, and learn about the rich history that has shaped this remarkable structure.

The Danube now meanders through a broad, open basin, and as you continue on your journey, a striking whitewashed castle comes into view, perched majestically on the landscape. In Scheer, the river takes a dramatic 180-degree turn, offering a scenic vista.
As you cycle on, you’ll be greeted by the charming Bartelstein Castle, beautifully situated beside the river. Another highlight along this stage of your tour is the enchanting hanging gardens of Neufra, located at the castle there. The cycle path runs parallel to the Danube, leading you onwards to Riedlingen.
Upon arrival, you’ll be captivated by the town’s picturesque half-timbered houses, which lend a distinctive character to the townscape. Your overnight stop here promises to leave a lasting impression.
