Frickenhöhle, Karst cave entrance in Farchant, Germany
Frickenhöhle is a karst cave with a total length of 3,222 meters on the western slope of Hohen Fricken mountain near Farchant. Its interior contains large halls, branching passages, and several underground lakes distributed throughout different sections.
The cave formed over millions of years through water erosion in the Estergebirge region and is one of Germany's largest karst formations. Its present structure reflects the continuous work of underground water streams that shaped the passages and lakes.
The name comes from the Hohen Fricken mountain beneath which the cave extends. Today, visitors and researchers use the site to study karst formations and underground water systems.
The cave is accessible via a steep hiking trail taking about 1 hour 45 minutes from Farchant. Venturing deeper into the system requires neoprene gear or rope climbing skills to navigate water-filled sections and narrow passages.
Inside are several water-filled siphons and a vertical drop of about 60 meters between different levels. During heavy rainfall, water flows out from specific openings, revealing the active geological dynamics of the system.
