It is located on the northern part of Kalamos in an inaccessible from the sea point and it is accessed only through a rough path. Its impressive mouth is over 10m high. Further inside, the water dripping on the walls forms golden-green deposits, columns and natural ponds, while the stalactites are still being formed. The locals believe that its interior ends to bigger depths traversing along Kalamos with an outlet to another smaller cave in the northern part of the monolithic rock.
