9Blautopf, Baden-Württemberg

Located near the small town of Blaubeuren, the Blautopf is a natural spring that’s famous for its strikingly blue water.

The vivid hue of the water, which ranges from turquoise to deep blue depending on the sunlight, is caused by the high concentration of limestone in the spring. Surrounded by dense forests and nestled at the foot of the Swabian Jura, the Blautopf is both a beautiful natural spot and a place of mystery—local legends tell of an enchanted underwater cave system that extends far beneath the ground.
