This park is a great place to explore with kids. The historical mine tour looked cool, but I wasn't…read moresure how my four-year-old would do so we skipped it this time. But the park itself is a great place to walk around, with big mining equipment from several eras spread around, restaurants in repurposed historical buildings, walking trails through the forest, a "mini-zoo" with a couple goats, and a small zip line.

There are perfomancies in local amphitheatre and also couple of exhibitions. The biggest one is about fairy tales characters. There is not much to say about history so I guess that´s why armoury and other typical castle´s exhibitions are ok with with one room each (and not many exponates). Also more descriptions about certain things would be nice. Anyway. I guess this place could be on your "to see in Ostrava" list.
