I just look on Google Maps, find some spot I've never been to and find a circuitous route to and from and see something new.
if you haven't yet, try out komoot. crowd sourced POI, amazing route finding depending on the parameters you put in (road, gravel, mtb, hiking etc). my go to routing software for the bike, found so much amazing roads/trails around berlin i would have never found on my own.
