Take the virtual history tour~10-15 min, but very informative. About 5 euros. There is no walking tour or tour guide for the castle. Some things are in English, but there is much only in French. A translator app for those signs will help tremendously. The inquisition museum(s) are pretty good. You must realize that along with the incredible views there was also a lot of death and torture here. History buffs will really enjoy it.

Very well organized. We left on time in a very comfortable bus. He brought us to the main entrance of the city and picked us up at the same place. Rest of the day free. I didn't have too much or no time. It is a place that is really worth it. As it was 40°, I saw the walls from the outside from the little tourist train that leaves exactly where our bus left us.
