2021 Map of Port San Luis

About this map

Port San Luis serves as the focal point for this section of the Central California coastline, situated at the edge of San Luis Obispo Bay. The landscape is defined by the sharp rise of the Irish Hills, where numerous canyons like Diablo Canyon, Irish Canyon, and Wild Cherry Canyon cut through the terrain toward the Pacific. High points such as Mount Buchon, Saddle Peak, and Green Peak provide a dramatic backdrop to the rugged shoreline. Historically significant maritime features including Point San Luis, Whalers Island, and Smith Island mark the southern reach of the map, while numerous offshore hazards like Santa Rosa Reef and Pecho Rock suggest the navigational challenges of this coastal stretch. A network of trails and roads, such as the Pecho-Coast Trl and Diablo Canyon Rd, connects the upland canyons to the sea, illustrating the enduring relationship between the coastal hills and the bay.
