A must in Gibraltar

The view from the top is amazing and although the monkey's seem a bit bored of all tourists taking photos it's great fun to see them chase each other. From the top you more or less have a 360 view and on a clear day you're supposed to be able to see the African coast.
It's a bit disappointing to see the trashed stone huts (I assume these have been some shelters for the monkeys) but besides these the surroundings are very nice.
