Caves , cliffs , springs , and world cultural heritage characterize the Alb-Donau district. Here you'll encounter unmistakable natural phenomena, such as the Blautopf karst spring in Blaubeuren and a fascinating cave system, crowned by the UNESCO World Heritage Site "Caves and Ice Age Art of the Swabian Jura ." 40.000-year-old ivory figurines—the oldest works of art in the world—are presented in the Prehistoric Museum. But the Alb-Donau district offers even more to see, including ancient castles , palaces, and monasteries . Much can be discovered while hiking on 20 Ice Age trails or exploring by e-bike on 23 themed cycling tours.
