Sesalac Cave is a place where nature has been quietly shaping its majestic story for thousands of years. In the cool shade of its underground chambers, you’ll discover formations created by the patience of water and time, and every step leads through a space filled with peace, freshness, and the unique beauty of karst.
About
Sesalac Cave is situated in the area of Sesalac village on the southern slopes of Mount Ozren, it is a natural monument located 16.5 km from Sokobanja and 255 km from Belgrade.
The cave is illuminated and richly adorned with cave formations: stalactites, stalagmites, and travertine pools. The idyllic picture of this unique speleological site is completed by a cave spring, through which a stream flows—namely the Zarvinska River, a left tributary of the Sesalačka River, which is the right headwater of the Moravica River - Sokobanja.
The cave is a subterranean form of karst relief, treated as an integrated dissolution cave system, formed by dissolving, with known input and output parts of the system.
A picnic area has been arranged at the cave entrance, and in the immediate vicinity there is also an artificial lake suitable for swimming in the summer months.
Sesalac Cave is a significant habitat for many protected species of bats, including four strictly protected species, and is also unique for one of the largest bat colonies in the Balkans.
It is protected as a natural monument of the II category and is one of the most beautiful speleological sites in Serbia.

Speleological features
Travertine pools
The travertine pools of Sesalac Cave are among its most recognizable natural formations. Gently shaped by the flow of underground water, these stone cascades resemble natural basins that shimmer in the cave’s twilight. Their layers and rims bear witness to nature’s long, quiet work—a process that unfolds over centuries and gives the cave its distinctive, calming appearance.
Stalactites
The stalactites decorating the ceilings of Sesalac Cave resemble stone “icicles,” patiently formed drop by drop over time. Whether slender or massive, they softly reflect the light, revealing an underground beauty that takes millennia of patience to emerge. Walking past them, it feels like you’re seeing the living history of water and stone.
Stalagmites
On the cave floor, stalagmites rise as silent witnesses to centuries of mineral deposition. Their shapes, ranging from low and rounded to tall and column-like, make the chambers even more impressive. In some areas they approach the stalactites above, creating monumental natural sculptures that reveal the cave’s depth, dynamism, and age.
Rare and protected species enrich the natural potential
Bats
Sesalac Cave is one of Serbia’s most important summer breeding roosts and winter hibernation sites for bats.
Pseudoscorpion
Sesalac Cave is also home to pseudoscorpions (Pseudoscorpionida, Pseudoscorpiones), tiny arachnid-like animals that closely resemble scorpions.
