The cave acted as a secret shelter for locals during the Ottoman occupation and later during the German occupation in World War II.
The interior contains a small waterfall that remains active depending on seasonal water levels.
It is connected to the Monastery of Prousos via a dedicated hiking trail that traverses the scenic gorge.
The geological structure of the cave was formed through centuries of water erosion within the limestone layers of the Evrytanian mountains.
Black Cave, or Mavri Spilia, is a prominent natural cavern located near the village of Prousos in the Evrytania region of Greece. The site is characterized by an internal waterfall and accessible rocky chambers that draw hikers through a rugged mountain landscape. A path equipped with wooden bridges and stairs leads visitors from the nearby Monastery of Prousos to the cave entrance. The interior features stalactite formations and a natural environment formed by the erosion of the surrounding limestone cliffs. It serves as both a natural attraction and a historical refuge for locals during various conflicts. The trail requires navigating steep sections and narrow passages carved into the gorge walls.

Wear sturdy hiking boots with excellent grip, as the wooden pathways and rock surfaces can be slippery.
Bring a headlamp or flashlight, as the interior of the cave gets dark and natural lighting is limited.
Carry a light windbreaker or sweater, as the temperature inside the cave is significantly lower than the ambient external air.
Attempting the hike during or immediately after heavy rainfall, as the wooden bridges and steep paths become dangerous.
Access may be restricted during winter months due to snow or severe weather conditions in the Evrytania mountains.
Respect the natural environment by not touching stalactites and carry out all waste to preserve the ecosystem.
