Not cheap as you have to pay for tours of each part of the site. The process is well run but again this is large scale, mass tourism; so be prepared to be part of a large group. My shopping focused, family thought that the very extensive gift shop in the very large visitor center was also great. Non English speaking Asian tourists struggle to listen / comprehend / follow the required tour rules. The free time out in the immediate Castle grounds was the highlight for me as I could take my time to take it all in and capture some images. Well worth a half day and given time we all should plan to spend more than 1 night locally here on the San Fran to LA road trip. I would prebook a tour(s) at least 1 day in front. Major ongoing drought is affecting the general landscape as of July 2014 but the immediate Castle grounds are still very well maintained.
