We toured Ksiaz Castle (Zamek Ksiaz), the underground tunnels of Project Riese, and the Palm House (Palmiarnia) in mid-October, a very enjoyable day, and well worth the trip. We did experience two suboptimal staff experiences. At the ticket window, the staff person didn’t understand that we wanted two tickets, necessitating two separate transactions. After finishing the tunnel tour, when we went to pick up the audio guide to enter and tour the castle, the staff person was rude, initially unintelligibly rejecting our tickets, which we had to point out were valid for the castle. As for getting to the castle from Wroclaw, because we preferred to travel on our own, at our own pace, we chose to take public transportation. Because our arrival time would not be precise, and underground tours are entry timed, we decided to purchase our tickets upon arrival, finding availability and no line. We did the underground tunnel tour first, as it began within a few minutes. While the Polish speaking tour guide led the group, audio guides were provided in many languages, triggered automatically along the route. We then did the independent castle tour using an English audio guide. From there, we had a nice walk down to the Palm House, which was included with the admission ticket. As an example of how to get to Ksiaz by public transportation, I will summarize our route, with other suggestions. We took the train from Wroclaw Glowny to Walbrzych Miasto, which is the first of two possible train stops in Walbrzych. After a reasonably short wait across the street, we were able to get on bus 8, making sure the final stop was Jezdziecka- Zamek Ksiaz. I suggest checking the bus schedule in real time, to estimate the wait time, for possible alternative consideration. At the castle, there is a choice of two stops. We got off at the first one (Piastow Slaskich) by the stables, which is a slightly longer walk on a smooth surface with a gentle rise. An easier, fast alternative would be to take a taxi from the Walbrzych Miasto train station to the castle. There were taxis waiting there, even mid-morning on a Tuesday in mid-October. Our return trip was much easier, since we went to the Palm House last. From nearby, buses 8 and 12 go to the Walbrzych Miasto train station. An alternate return option from the Palm House would be to take bus 9 or 12 to the other Walbrzych Szczawienko train station. The castle website has a map showing the local transportation and walking options.
