Insider tip Blautopf: The turquoise water wonder spring in Blaubeuren!

For many, holiday season means discovering new places and exploring hidden treasures. The Blautopf in Blaubeuren, a charming town in Baden-Württemberg, is a secret tip that you shouldn't miss. A karst spring that attracts everyone's attention with its striking, turquoise water has not only captivated geologists. Baden24 reports that the spring is 22 meters deep and has a constant water temperature of around 9 degrees Celsius.

Originally native to Germany's deepest lake, the unique nature of the water gives the Blautopf its fascinating turquoise color. This happens through Rayleigh scattering: daylight absorbs all colors except blue and is refracted by the lime particles in the water. This natural wonder is not only a feast for the eyes, but also a geotourism highlight in the region.

A natural wonder with history

Did you know that the Blautopf not only serves as a spring, but also forms the origin of the Blau River? After 14.5 kilometers, this river reaches the Danube in Ulm, and so the Blautopf not only has geographical significance, but also historical roots. The legends surrounding this magical place are numerous. In “The History of the Beautiful Lau” Eduard Mörike writes about a water nymph, the mysterious creature that lives in the blue pot.

But the Blautopf not only offers picturesque views and stories, but also extraordinary opportunities for exploration. The surrounding cave system, including the famous Blue Cave, can be explored by experienced divers. The Blue Cave, which has been known since 1985, is around 1,500 meters long and completely filled with water. The “Apocalypse” cave, which has been discovered since 2006 and is dry, also has its own secrets to offer. However, access to the Blue Cave is limited to experienced divers as safety is the top priority here.

Current developments and visitor information

After extensive renovation work on the Blautopf area began in August 2024, the area has been accessible to visitors again since January 15, 2025.

LGRB knowledge highlights that the Blautopf, with an average discharge of 2,270 liters per second, is the second largest karst spring in the Swabian Alb.
