This Ultra Blue Hole in Germany is Amazing and seriously Ultra Blue. This was one of the most exciting off-the-beaten-path discoveries that I found while traveling across Germany with my kids, and it’s a lesser-known place even to Germans.
Blaubeuren is a historic town with evidence of human habitation dating back to the ice ages. In addition to the Neanderthal caveman discoveries, this place is still imbued with mystery with the weight of long history.
The Blautopf aka Blue Hole aka Blue Pot
Blautopf means “blue pot” in German.
The Ultra Blue Color of the Blue Hole took us by surprise
We honestly didn’t know about this place before stumbling upon it. The ultrablue color of the blue hole took us by surprise. I’ve never seen such blue and with some green plus the yellow color of the trees surrounding. Just gorgeous!!
Why is it so blue?
It was explained to me that the water has this amazing blue hue due to “Rayleigh-Streuung“ (Rayleigh Scattering). This is the same phenomenon that makes the sky blue. That means the Blautopf’s water must be very pure.

Massive Cave System Called the Blauhöhle
This blue hole is the opening to a massive underground cave system that branches all the way under the Swabian Alb.
How Deep is the Blue Hole?
The cave system begins 21 meters (69 feet) deep but the actual depth of the hole is much deeper than that even.
