2022 Map of Las Pulgas Canyon

About this map

San Onofre Mtn and the coastal uplands of northern San Diego County define this Pacific shoreline corridor. The landscape is characterized by a series of deep drainages including Las Pulgas Canyon, Aliso Canyon, and French Canyon, which cut through the high ground of Stuart Mesa toward the sea. Human activity is concentrated along the coastal shelf, where the historic route of El Camino Real and the Old Pacific Hwy parallel the modern transportation arteries. Settlements like Las Flores and Agra sit near the sensitive coastal environment of the Las Flores Marsh. To the southeast, the terrain transitions into the Ysidora Basin near the mouth of the Santa Margarita River. The mapping of numerous interior roads such as Basilone Rd and Stuart Mesa Rd suggests the managed nature of this coastal territory, balancing steep canyon topography with strategic coastal access.
