How can I find paths recursively to a site on a website?

I am trying to find a possible path from site-starting-point to a given site. One can simply think of it as: Start at site-starting-point and go recursively with infinite depth until you find site X. Another solution that would be fine with me is if it does this for every possible site and I can search through it afterwards. In theory wget -r website must do something like that internally. Is there a way to access this data so I can avoid writing my own script?
