We were picked up by Pawel from our hotel and we’re driven in a sedan instead of the usual bus. Our guide provided an interesting and varied commentary. We were shown by our guide to various entry points and then left to enjoy the tour around Ksiaz castle with an excellent audio guide. The visit to the Tunnels at Osowka were the least interesting being very dark and with uneven flooring. We had audio guides in English but a torch or headlamp would have helped. We were with a large group of Polish students. The castle and the the church of Peace were the highlights and a great tour guide who was a history buff. Highly recommended.
