Price: 23 zloty. With audio guide it is 13 zloty more (you must leave an ID document or 100 zloty)
I recommend taking the audio guide, as it provides more information than the information on the panels, especially in the crypt and chapels, particularly about the Polish kings buried here. Unfortunately, it is not possible to take photos except in the Sigismund's Tower (if you suffer from vertigo or clausteophobia, I recommend not going up there). The visit is totally worth it more for the history than for the architecture of the cathedral (it is a mixture of styles and is simply ornate). Don't forget to see the dragon bones before entering the cathedral! (They are actually from whales, mammoths and rhinoceroses). Also, the views from the tower are worth it.
The entrance includes a visit to the cathedral museum and the archdiocese museum. I was short on time so I didn't visit them.
