How about a guided urban exploration tour in a city he hasn't explored yet? You could look for a reputable company that offers tours of abandoned buildings, hidden alleys, and lesser-known landmarks in a city he's wanted to visit. Alternatively, you could put together a DIY urban exploration kit with a map and a list of sites to explore, a portable camera, a flashlight, and a journal for him to document his adventures. You could also design a custom photo book with his favorite urban exploration pictures and destinations. Another option is a piece of urban art or a coffee table book with stunning photography of cool city feats. Hope this helps!
Or you can get him a star map with the date of your first kiss.
