On the left, behind a wooden post, a tunnel which was dug in 1974, protected by a grating and leading to a side sequence of corridors, can be found. The narrow and muddy corridors, 160 metres in length, with five little lakes inhabited by a rare crustacean studniczek tatrzański (‘Tatra’s welldweller’), are closed to visitors. The other, higher part of the middle chamber was used, in the 17th and the 18th centuries, for storage and as a banquet room by a tavern located in front of the entrance over Vistula river.
The southern and the last ’C’ chamber is 11m long, 5.8m wide and 4m high. A stone vault is supported by a set of brick pillars. This section is decorated by rock projections, chimneys and karstic fissures. This is where the main room of the tavern was. We exit the Cave through a pointed arch portal and a vestibule. On the Vistula Boulevard visitors stand in front of a sculpture of the Wawel Dragon created by Bronisław Chromy in 1972.
