The entering the cave is on the left bank. It has a monumental gateway of 15 meters high, after what we get in the Great Hall lit by four chimneys. The entire string floor is covered with large blocks of rock, through the waters creep with a roaring sound, forming forming rapids and waterfalls that must be passed. It follow a narrow area and deprived of light, until we reach the area below the Window I, another venture that pierces the limestone floor. Next is a narrow canyon, with no light, with swirling grooves, typical of erosion, after what we get on the exit from Radesei meadow.
