I'm in Prague next week and I'd like to tour both Karlštejn and Konopiste castles. The problem is, they are located in opposite directions of the city. In addition, for Karlštejn, in order to visit the Chapel of the Holy Cross (Tour I), the website states that a reservation is necessary. I would assume that most tour companies would simply do the other tour without reservation.
Any recommendations for this situation? I found a tour company that visits both castles, but without visiting the Chapel at Karlštejn. Is it worth it? Is there a better tour company? Could I do both castles on my own without booking a tour?
