I'd say it's both. We probably have the innate skill but it must be developed. Some are better than others, of course. You can use landmarks and the path of the sun and things like that, and it may become second nature making it feel like a "natural" skill when in fact your brain is processing all these cues subconsciously, leaving the rest of your brain to hum the tune to "Maneater" by Hall and Oates over and over again while on a hike, driving you insane.
Some studies have shown that we have a tendency to simplify mental maps of our surroundings: curvy roads become straight, significant objects becomes "closer", lesser objects are ignored, things like that. Draw a freeway map in your closest big city and see how accurate you really were. Translate that skill into the backcountry and you can appreciate the work it takes to develop a true sense of direction.
