Welcome to the Homepage of "Arbeitsgemeinschaft Blautopf"!

The "Arbeitsgemeinschaft Blautopf" is a cave research club, currently consisting of 18 members. It was founded in 1997 by members of the "Höhlenforschungsgruppe Ostalb/Kirchheim e.V.". The mission of this organisation is to scientifically explore the Blautopf underwater cave.



The Blautopf is one of the largest karst springs in Germany. The largest ever measured flow of this spring amounted to 32 000 l/sec. The spring basin is 22 m deep.



On these pages we would like to provide interested visitors as well as members and friends with information concerning the Blautopf underwater cave and its exploration.
