Kossuth Cave

Kossuth Cave is an underground system running through limestone rock with active water channels feeding into the Nagy Tohonya spring. The water maintains an average temperature of 14 degrees Celsius as it flows through the passages.

Scientists first entered the cave in 1956 by clearing the entrance through controlled explosions, marking the start of documented exploration. This breakthrough expedition opened the underground system to systematic research.

The cave is named after Lajos Kossuth, an important Hungarian historical figure whose legacy connects to the natural landscape. Visitors sense this link to the nation's past as they move through the passages.

Visitors should register in advance as groups and wear protective clothing and rubber boots due to the active water system throughout the cave. Smaller groups of five to ten people work best for safe passage through the narrow sections.

The cave network includes submerged passages that divers reached through specialized exploration, discovering a terminal siphon in 2010. These underwater sections reveal just how far the system extends beneath the surface.
