The Cabrillo National Monument sits at the tip of the Point Loma peninsula in San Diego—not vaguely "in Southern California." Precision matters for navigation and context.
1800 Cabrillo Memorial Drive
San Diego, CA 92106
At the southern end of Point Loma, commanding the entrance to San Diego Bay and panoramic views of the Pacific, the bay, Coronado, and downtown San Diego.
Juan Rodríguez Cabrillo, the Portuguese explorer sailing for Spain, who on September 28, 1542, became the first European to navigate the coast of present-day California. He landed at "San Miguel" (now San Diego Bay).
