Sounds strange in Englsh, more natural would be "The girls want to visit the cities".... they already have the cities they want to visit in mind is assumed because they "want". So the article is natural to implicit refer to the specific cities they have in mind.
Unless, of course, all they've visited before are villages, and they're bored with that. I could understand why they want to visit cities. :)
