Mougri cave is located in the middle of Kouloukonas mountains, just northwest of Vossakos monastery. It was formed within the “Plattenkalk” rocks, probably along with one of the big faults in the area.
It is a very impressive cave with rich decoration on its side walls. It is formed by two main halls of about 2 thousand square meters in extent. Remnants of water rimstone dams in its deepest part indicate that it was active many years ago. It has been used by humans, at least since the Minoan era. The cave can only be accessed, however, by cavers.
