There are 350 m. of corridor. The third level lies below the second where channels carry the water tumbling from a waterfall 2 m. high at the end of the cavern. The stream can be seen from the end of the tourist trail, disappearing 10 m. lower down in the inaccessible channel of the third level. It re-appears in the first chamber of the cave, where it passes again into a channel to discharge as a spring 25m. below the entrance to the left. The course of the river was traced by fluorescein, a coloured chemical substance.
Nearby villages make use of the supply.
