Any tips for being present when the Hejnal is played in Krakow ?

I have read that it's possible to climb one of the towers at Krakow's St Mary's Church and be present when the bugle player sounds the hejnal.

Does anyone know how to go about doing this ???

Yes, I saw your post yesterday and it sparked my curiosity so when I was in Market Square today I asked about it at the ticket booth to St. Mary's Basillica. It is open to the public, but only May - Sept 30 during peak season, during daylight hours. Not sure of the exact hours but she said Tues., Thurs., and Sat. No idea if those will be the exact days for next year though, that's what it was this year.

as krkPrincess wrote or you can always look up and there it is....
