Every campsite within an hour range of Big Sur was full, and it was getting dark so we opted for this road. It is the only road where dispersed camping is allowed but beware: it is narrow, steep, unmaintained, and surrounded by cliffs. If you happen upon a pull out that is not occupied, does not have a private property sign, and is somewhat flat, then it works as a spot to sleep that feels like you’re on the edge of the world.
