We drove to the top (we'll walk up the steps next time). The fortress is much more extensive than it looks from the town. An amazing collection of bastions, mostly in good condition. There are no safety rails within the fortress (just some over window openings at the cliff edge) so not sure this place is suitable for children (unless you keep hold of them) so the I am puzzled by one of the recent reviews. Walk up a stone staircase and there are fifty feet plus drops a couple of steps away. I don't get vertigo, but I did here. But this all added to the experience. The leaflet was brief and there are no information boards, so I will do my own research before visiting again next year.
