Blautopf

A deep blue lake, which incidentally also inspired Eduard Mörike to write his "Stuttgart Hutzelmännlein" - written in Swabian dialect with a tongue twister: "S'leit a Klötzle Blei glei bei Blaubeura, glei bei Blaubeura leit a Klötzle Blei." of the beautiful Lau, a cross between a woman and a water nix, which her husband banished to the blue pot because she could not laugh and only bore him dead children.

The blue pot in Blaubeuren in Baden-Württemberg is the second-richest karst spring in Germany. This is where the blue springs, which after about 22 kilometers in the city of Ulm flows into the Danube.

Known is the blue pot for the depending on the light more or less intense, but always striking blue color of its water. The blue color is caused by a physical effect of light scattering (so-called Rayleigh scattering) on the nanoscale lime particles that are dispersed in the water. Due to their small size, the blue light is preferably scattered and produces the blue glow. The same effect can be observed with the Blue Lagoon in Iceland; There, the effect is caused by nanoscale silicate particles.

The blue pot is the second most water-rich karst spring in Germany after the Aachtopf.
The blue color is caused by the light scattering on the smallest lime particles in the water. Due to the small size of the particles in the nanometer range, the blue light is preferably scattered.

The blue pot is followed by a large, mostly underwater cave system, which is explored by divers. In 2006, a 170 x 50 x 50m dry cave was discovered.

Already felt 100 times been there ... But a Blaubeuren visit without having been on Blautopf is like a visit to Berlin without the Brandenburg Gate ... 😉

The Blautopf is a karst spring, 21m deep, in which springs the blue, barely imaginable that tile up to 32,000 L / s

Due to light scattering due to small molecules, this results in a special natural spectacle. Best to visit outside the holiday season, as the tourist crowd is now very large.

A historical place. There springs the blue, which flows into the Danube in Ulm.
Some people discover the "beautiful Lau", according to legend, a water mermaid living there ...

Really a very special play of colors, the sunlight creates many different shades of blue.
It is best to come by very early so that you can benefit from it.

The blue pot is beautiful. You can easily walk around it. There is a great café right on the Blautopf.

There is something magical about this little lake. The turquoise, blue and green glowing water has long fascinated us. We have been there countless times and would love to come back. Just not on nice weekends as it is overcrowded.

The blue pot is a 22 meter deep spring.
As beautifully blue as the water shines against the light rock, bathing and diving in it is forbidden

The blue pot impresses with its very beautiful color 😊. I can only recommend 👍

Very impressive color in the blue pot, also the entrance to a strongly branched cave system.

Out of this world, belongs to the magical places‼‼‼
There are wonderful hiking trails right next to it with beautiful views and good air, for example to the kissing sow.

You should definitely see the Blautopf. Depending on the weather and solar radiation, the karst appears differently blue.

Blue green water and crystal clear.
There is also a small hiking trail around it.
There are many places and benches to linger.
The physical well-being is also taken care of.

What can I say - due to the incredible amount of rain recently, the Blautopf is currently more milky than blue, despite the bright sunshine today. Anyway, still impressive. You don't see it every day. In addition, it "boils" as a result, that is to say, you can see in the middle the water gushing up from the karst spring. And that's probably not seen that often, according to the locals!

Despite the many tourists, the Blautopf retains its special charm. If you stand in front of the turquoise-colored cauldron, all the myths and legends of this place come to the fore and you experience the magic that rises from the water like the Schöne Lau.

The most famous karst phenomenon in Blueburden is the Blautopf. After the Aachtopf, the Blautopf is the largest karst spring in Germany.The Blautopf owes its creation to various circumstances. The Alb plateau consists of fissured and permeable limestone. The rains on the Alb do not collect in rivers, but immediately seep into the subsoil. Extensive cave systems have arisen within the mountain range, which, depending on the water level, lead underground cave rivers or, in the meantime, are dry caves.

Quote Wikipedia: "The Alb water supply was a pioneering hydraulic engineering achievement, the implementation of which began in 1870"

I have never seen it so blue anywhere. There is a restaurant next door, but it is quite overcrowded.

Some paths are currently impassable

Clear water in an almost round lake below the slopes. With the half-timbered mill and the monastery in the background, a great sight. In the morning when there are not so many tourists and the first rays of sun just fall into the water, a fantastic sight.
