This a really nice park and definitely worth a visit. The easiest way to get there is by car, but if you don't have the luxury of that there is always public transport. I used the 210 busline and got off at czajowice. From there it's about a 10-15 min to the park. The park offers some nice things such as caves and some small remains of a castle (just the gate house). It has also a nice selection of restaurants at different places along the main road going through the park. All the (information) signs in the park are in almost exclusively in Polish. However the signs indicating walking routes are easy to follow. Do keep in mind that the extra activities (such as the caves) all cost money and they don't accept card, only cash. It's not that expensive though (one of the caves was 8 zloty and the gatehouse was 3 zloty). Also have some extra cash for the public transport, not all machines on the trams and busses accept card. The easiest thing would be to buy the tickets before you go (two 60-minutes tickets should be enough to go back and forth, these are five zloty each).
