On the last section, the magnificent alpine panorama is always present. There are some more hills to climb until you can finally savor the final descent down to Lake Constance.On the western outskirts of Wangen im Allgäu you cycle through an attractive meadow landscape. The bike route descends into wooded valleys and then climbs to green heights. In a wide arc you drive through Haslach and Neukirch. The two places are surrounded by several nature reserves, in which picturesque ponds are embedded in lovely hills. After almost 18 kilometers, it is worth making a detour to Achberg Castle, which can be visited from Friday to Sunday and on public holidays.A little later you cycle slightly higher in the gentle curves of the wild and romantic Argen, which has dug deep into the landscape near the hamlet of Summerau. In the village of Berg the terrain slopes and you can get drunk on the fantastic descent. Apples and cherries ripen between the villages, while extensive rows of hops spread out on the favorable slopes and sunny locations. In between, rows of vines stretch down to the shores of Lake Constance, benefiting from the mild sea climate and the sun-drenched southern exposure.After all the different landscapes and the cultural highlights of Upper Swabia, you roll into Kressbronn. In the holiday resort, the Schlössle with its museum is particularly popular. The exhibition presents historical ship models that were created by Ivan Trtanj in a detailed work.Finally you cross the small park and roll down to the shore. In the face of the magnificent Lake Constance panorama, above which the Alpine chain looms large on the opposite bank, a more than 150-kilometer cycle tour on the Danube-Lake Constance cycle path comes to a worthy end.You can find more information about the fourth stage at oberschwaben-tourismus.de/touren/donau-bodensee-radweg-etappe-4-von-wangen-nach-kressbronn-cce534ece4.
