How about gifting your daughter a book about urban exploration that features unique and hidden places to uncover in cities around the world? Another idea could be a ticket or guided tour to explore abandoned locations or hidden spots in your city or a nearby city that she hasn't had a chance to explore yet. You could also consider giving her urban exploration gear such as a good quality flashlight or a comfortable pair of walking shoes, or even a camera to capture some amazing shots while on her adventures.
Or you can get her a star map with an important date you share.
