Cerje cave, Natural cave system in Pantelej, Serbia
Cerje Cave is a cave system in Pantelej that extends 7,149 meters through limestone formations with passages reaching heights of 40 meters. It consists of several named sections including the Moon canal and Salomna chamber, formed through water erosion.
The cave was first explored in 1976 by members of the Belgrade Mountaineering Union with an initial documented length of 4,240 meters. This made it Serbia's longest cave at that time, before later explorations revealed its full extent.
The cave takes its name from an underground river that locals called Provalija, referring to water disappearing into its depths. Speleologists later renamed it Cerjanka, reflecting the water's role in shaping the site.
The entrance is very narrow, offering minimal space for visitors to pass through. The site remains undeveloped for touring, so visitors should expect basic conditions.
A distinctive feature is the Moon canal, a section with black limestone formations situated between a siphon and a large chamber. These structures formed through specific erosion patterns that give the area its distinctive appearance.
