We went on a Sunday by public transport, bus 304 which is down a street opposite the Galleria. We tried to go by train but because it was a Sunday, trains were every two hours. The bus trip was great with good views of the castle en-route. At the Salt Mines we were in a group of 100 people which was far too many. We had a guide and our own audios so we could hear her but several off the audios failed because the batteries hadn't been charged properly. I had read reviews and been advised by friends that the salt mines mustn't be missed. My own personal view is that I am glad I visited but it wasn't the highlight of my trip.
