Visited the Historic Silver Mine in December 2017 and I have to say it was worthwhile. If you plan to visit it, I would recommend you to make a reservation, it made our situation easier. I can confirm that the minimum number of people is 4, we were 3 but as I agreed to pay for 4 we were allowed to visit, for which I am very thankful to the personnel.

The tour start by watching a movie about history and the site in a small cinema. Later it continues in a multimedia museum with interesting details about history, tools and machinery. After that follows the visit of the site itself.

Our guide was a very good and her enthusiasm was a big part of the overall positive experience.
