Climbing out of his boat and onto shore in 1542, Juan Rodriguez Cabrillo stepped into history as the first European to set foot on what is now the West Coast of the United States. In addition to telling the story of 16th century exploration, the park is home to a wealth of cultural and natural resources. Join us and embark on your own Voyage of Discovery.
The Old Point Loma Lighthouse stood watch over the entrance to San Diego Bay for 36 years. At dusk on November 15, 1855, the light keeper climbed the winding stairs and lit the light for the first time. What seemed to be a good location 422 feet above sea level, however, had a serious flaw. Fog and low clouds often obscured the light. On March 23, 1891, the light was extinguished and the keeper moved to a new lighthouse location closer to the water at the tip of the Point. Today, the Old Point Loma Lighthouse still stands watch over San Diego, sentinel to a vanished past. The National Park Service has refurbished the interior to its historic 1880s appearance - a reminder of a bygone era. Ranger-led talks, displays, and brochures are available to explain the lighthouse�s interesting past.
The Old Point Loma Lighthouse is a reminder of simpler times - of sailing ships and oil lamps and the men and women whom day after day faithfully tended the coastal lights that guided mariners. In 1851, a year after California entered the Union, the U.S. Coastal Survey selected the heights of Point Loma for the location of a navigational aid. The crest seemed like the right location: it stood 422 feet above sea level, overlooking the bay and the ocean, and a lighthouse there could serve as both a harbor light and a coastal beacon. Construction began three years later. Workers carved sandstone from the hillside for walls and salvaged floor tiles from the ruins of an old Spanish fort. A rolled tin roof, a brick tower, and an iron and brass housing for the light topped the squat, thick-walled building. By late summer 1854, the work was done. More than a year passed before the lighting apparatus - a five foot tall 3rd order Fresnel lens, the best available technology - arrived from France and was installed. At dusk on November 15, 1855, the keeper climbed the winding stairs and lit the oil lamp for the first time. In clear weather its light was visible at sea for 25 miles. For the next 36 years, except on foggy nights, it welcomed sailors to San Diego harbor. The light had only a short life because the seemingly good location concealed a serious flaw: fog and low clouds often obscured the beam. On March 23, 1891, the keeper extinguished the lamp for the last time. Boarding up the lighthouse, he moved his family and belongings into a new light station at the bottom of the hill. Today you can see the "New" Point Loma Lighthouse from the Whale Overlook, 100 yards south of the Old Point Loma Lighthouse.
At the time Juan Rodriguez Cabrillo sailed into San Diego Bay in 1542, a rich diversity of life was present, ranging from desert cactus to moisture-loving algae, tarantulas to sea slugs, and gray foxes to sea lions. Approximately 3,000 Native Americans lived in the San Diego area at that time. The Kumeyaay, or Diegueos according to the Spanish accounts, lived simply in the environment but likely impacted the landscape through the use of fire. Today, largely due to the impacts of European colonization and centuries of growth and development, the habitat Cabrillo saw is now among the rarest in the world. Although only a remnant of that biologically diverse ecosystem remains, it is well worth visiting and protecting. This unique diversity of plants and animals occurs here because Cabrillo National Monument lies at the southern-most extent of some plant and animal ranges, and the northern-most extent of others. Located in a large metropolitan area just west of the city of San Diego, Point Loma encompasses more than 660 acres of native habitat. Cabrillo National Monument rests protected on 160 acres at the southern-most tip of the peninsula, which is bordered by the Pacific Ocean on the west, San Diego Bay on the east, and urban development on the north. Cabrillo National Monument enjoys a Mediterranean climate characterized by warm, dry summers and cool, mild winters. Weather data is recorded for San Diego at Lindbergh Field (the airport) which is directly across the bay from the monument. The average annual temperature is 64 degrees and the average annual rainfall is a scant 9.5 inches. Rainfall is concentrated in the winter, from November to April, but the amount can drastically change year to year, from 3.4 inches to 19.4 inches. This variability in rainfall causes certain types of plants to thrive one year and barely survive another. Nature makes up for this lack of rain when cold air from the ocean meets the balmy air on the land and dense fogs roll in. The fog adds moisture to allow species requiring more water to coexist with the desert plants and animals. The ocean also keeps air temperatures mild year-round, which allows heat-loving cactus to grow next to evergreen shrubs common in cooler climates, salamanders to walk past sunning desert snakes, and mosses to grow in the cool shade, a stones throw from where parched lichen cling to dry, hot boulders. In addition to the unusual climate, Cabrillo National Monument hosts many uncommon species of birds because of its location along the Pacific flyway. Over 200 species of birds have been recorded at here, including land, shore, and sea birds. It is not uncommon to see a tiny ruby-crowned kinglet hopping through a bush on land, huge brown pelicans flying silently low in formation over the ocean waves, and a solitary red-tailed hawk soaring overhead searching for its next meal. On the west side of the park, a rocky interface between the land and the ocean provides a spectacular coastline and fascinating habitats to explore. A myriad of marine plants and animals, including lacy red and slimy green algae, sluggish sea hares, leggy octopi, darting fish, and the always entertaining hermit crabs, live in this rocky intertidal area. Also on the west side of the park and just past the intertidal area, but not yet reaching the horizon, visitors can see the imprints of the kelp forest on the ocean surface. This subtidal zone is an underwater forest with large kelp that provides food and shelter for some of the animals that live there: snails, urchins, abalone, sea stars, kelp bass, sheephead, and octopi. From December to March, visitors can look beyond the kelp forest toward the horizon and see the Pacific Gray Whale pass by the shores on its annual migration from Alaska to Baja California, Mexico, where it will birth and rear its young.
