Cabrillo State Marine Reserve

Cabrillo SMR is located on the southwestern tip of the peninsula, and bordered by sandstone cliffs that slope down into the intertidal zone. About 76 million years ago beneath the Pacific Ocean, sand, mud, and gravel were compressed to create a sedimentary geologic formation known as the Point Loma Formation. These rocks were then molded by uplift and erosion into the Point Loma Peninsula. Fossils from this period can still be found in the SMR’s tidepools.

From the intertidal zone to rocky reefs, the SMR protects several thriving natural communities. In nearshore tidepools, mussels, barnacles, brittle stars, and gobies navigate daily tidal fluctuations and hide among mats of coralline algae, seaweed, and seagrass. In deeper water, leopard sharks and barred sand bass cruise the sandy seafloor, while California sheephead hunt urchins, and California spiny lobsters and abalone hide in rocky crevices shaded by towering giant kelp. Beyond the edge of the kelp forest in deeper waters, gray whales pass by during their annual migration between Alaska and Baja Mexico.

The SMR protects habitat for more than 200 species of migrant and resident birds, including brown pelicans, black oystercatchers, cormorants, and terns; many species can be seen soaring in the sky, resting on the rocks, or foraging along the rocky shoreline for food.

For centuries, Native American Tribes in California have relied on marine and coastal resources. Many of these Tribes continue to regularly harvest marine resources within their ancestral territories and maintain relationships with the coast for ongoing customary uses. The Kumeyaay people have lived in what is now San Diego County for thousands of years. The Kumeyaay traditionally harvest the coast's animals and plants for both food and jewelry.

Point Loma experienced its first recorded European visitor in September 1542 when Juan Rodriguez Cabrillo landed. Originally named “La Punta de la Loma de San Diego”, which means Hill Point of San Diego, the official name was later changed to Point Loma. The first European colonizers, a combination of soldiers, explorers, and missionaries, arrived in 1769. In 1848, the Treaty of Guadalupe Hidalgo gave ownership of the land to the United States. The treaty split the homelands of the Kumeyaay, leaving part of their people on either side of the border between the United States and Mexico.

In 1851, a year after California gained statehood, Point Loma, at 422 feet above sea level, was selected as an ideal spot for a lighthouse. However, low lying fog and clouds obscured the light, and it was decommissioned in 1891. When the United States government recognized the military significance of the location, Fort Rosecrans was established on the point. This military reserve afforded vital coastal and harbor defense throughout World Wars I and II. In October 1913, the half-acre of ground surrounding the old lighthouse was proclaimed Cabrillo National Monument to commemorate Juan Rodriguez Cabrillo. Today, the old lighthouse remains open to visitors, and the new lighthouse, automated in 1973, continues to warn mariners about the rocky point.

The shoreline along Cabrillo SMR is an accessible rocky intertidal area that offers ample opportunities for coastal exploration. The easiest access is through Cabrillo National Monument. During low tide, visitors can explore the diversity of life hiding in the tidepools. However, collecting any items, from rocks and shells to fish, algae, and any other marine resource, is not permitted within the SMR.

Cabrillo National Monument Visitor Center delivers interpretive information about the location's cultural and natural history, and offers striking views of the SMR and Baja’s Los Coronados Islands that lie offshore. Visitors can also get a glimpse of Ballast Point, thought to be the landing site of Cabrillo in 1542. There are walking paths within the National Monument, and Old Point Loma Lighthouse has a historically refurbished interior and remains open to the public as a museum. Sightseers have opportunities to view migrating gray whales from December to March, as well as more than 200 species of birds. This is considered one of the best birdwatching spots in San Diego.
