Lamprechtsofen

The Lamprechtsofen cave system extends through limestone formations for 60 kilometers, with 600 meters accessible to visitors through illuminated passages.

Regular explorations of the cave system started in 1822, leading to its public opening in 1905 with an innovative electric lighting system of 280 colored bulbs.

The German Alpine Club section Passau manages this natural monument, offering guided tours that explain the geological formations and underground water systems.

Visitors should wear sturdy shoes and warm clothing as temperatures remain between 4 and 6 degrees Celsius throughout the year inside the cave.

This cave system holds the record as the longest through-cave in the world, discovered when Polish researchers found a second entrance at 2,178 meters altitude in 1993.
