About this map

San Onofre Bluff and the narrow coastal corridor of northern San Diego County are defined here by a dense layering of historic and modern transportation routes pressed between the hills and the sea. The geography of the late twentieth and early twenty-first centuries is marked by the parallel lines of El Camino Real, Old Pacific Hwy, and Interstate 5, tracing the same path through Agra that travelers have used for generations.

The landscape transitions sharply from the high, dissected ridges of Foley Canyon down to the steep cliffs overlooking the Pacific Ocean. This map documents a sophisticated network of recreational paths, including the San Diego County Coastal Bike Route - North Trl and the Bluff Top Trl Trl, which provide public access to this restricted coastal edge. The presence of these trails alongside major transit arteries illustrates the ongoing balance between regional infrastructure and coastal preservation.
