Once you become familiar with an area and have a general idea of where things are located it's fairly easy to figure out the way. For an example, if you are heading over a mountain range, the road or trail is generally found at a low pass, and the way to the pass is generally up a valley. It's easy enough to get lost in civilization too. Many years ago I spent a summer riding around Europe. One day I needed some things while traveling through Munich. I parked my bike and headed down into the underground Stachus Passagen shopping center. I got totally turned around and came up a different way. I probably spent an hour wandering around in the city before I found my bike.
