The Society of California Pioneers, established in 1850, is dedicated to the study and enjoyment of California art, history, and culture. Founded by individuals arriving in California before 1850 and thriving under the leadership of several generations of their direct descendants, the Society has continuously served its members, the academic community, and the public. As the oldest organization West of The Mississippi, The Society opened the first library in California, as well as a grand hall for meetings, lectures, and social events. Today The Society operates a public museum and a research library, both housed in one of the iconic Montgomery Barracks Buildings on The Presidio of San Francisco's historic Main Post. Pioneer Hall features rotating exhibitions of art and artifacts amassed since 1850; free museum education programs for school-aged children, as well as public tours and events are offered. The Alice Phelan Sullivan Research Library, which houses a large portion of The Society's collections, is open to the public by appointment, allowing researchers and historians access to The Society's privately held repository of rare primary source materials. The Society's service to the community is designed to support scholarship and encourage new interpretations that illuminate and honor the diverse experiences of those who came before us. According to its constitution, The Society's mission is "to collect and preserve information connected with the early settlement and formation of this new state."The Society continues to be a membership organization, and "Membership is open to direct descendants of those who arrived in California prior to January 1, 1850."

Established in 1917, the Presidio Fire Department provides primary emergency response to the Presidio of San Francisco. During the 1940s, '50s and '60s the Presidio's Firehouse served as the headquarters station to a much larger department consisting of many Stations located at the various forts around San Francisco such as: Fort Baker, Fort Barry, Fort Funston, Fort Mason, Fort Winfield-Scott, Fort Cronkhite, Chrisy Field, and Angel Island along with fire prevention duties and air show fire protection at Hamilton Air Force Base after its closure and prior to its transfer to the City of Novato. Although most of the firehouses have long since been demolished, some still stand such as those located at the Presidio of San Francisco's Main Post, Fort Cronkhite, Fort Mason and Angel Island. The National Park Service maintains the daily log books dating back to the 1940s from several of the department's stations in the Park Archives of the Golden Gate National Recreation Area and they are available to the public for viewing. Over the years the Presidio Fire Department was reduced and left with two fire stations. Fire Station 1 was located in the Presidio of San Francisco's Main Post and Fire Station 2 was located in the Marin Headlands at Fort Cronkhite. In 1994, as a result of the Presidio of San Francisco's closure under the Base Realignment and Closure act the Presidio Fire Department and staff was transferred from the Department of the Army to the National Park Service and became the only full-time fire department within the National Park Service under the Golden Gate National Recreation Area, Division of Visitor Protection. However, as indicated by report #RECD-00-154 issued by the Government Accountability Office in 2000; the National Park Service as a whole was unable to effectively operate its various fire protection programs throughout the country. The GGNRA was no exception to this, and after years of struggling attempting to operate the Presidio Fire Department, the GGNRA began exploring options to rid themselves of the management burden of running a full-time fire Department.

Crissy Field is a public recreation area on the northern shore of the San Francisco Peninsula in California, United States, located just east of the Golden Gate Bridge. It includes restored tidal marsh and beaches.Crissy Field is a former United States Army airfield which is now part of the Golden Gate National Recreation Area. Historically part of the Presidio of San Francisco, Crissy Field closed as an airfield after 1974. Under Army control, the site was affected by dumping of hazardous materials. The National Park Service took control of the area in 1994 and, together with the Golden Gate National Parks Conservancy, worked to restore the site until 2001, when the Crissy Field Center was opened to the public. While most buildings have been preserved as they were in the 1920s, some have been transformed into offices, retail space, and residences.

Crissy Marsh is a wetland area in San Francisco, California, United States. Crissy Marsh has brackish waters, making an ideal habitat for many bird species along the Pacific Flyway. Here, freshwater runoff meets the salt water of the bay. It is 130-acres and located on the northern end of the San Francisco Peninsula. This salt marsh was largely destroyed to build Crissy Field, an airfield used during World War I and World War II. It has since been restored, with the airfield being removed. It now hosts abundant and recovering wildlife on the northern San Francisco coast.

San Francisco National Cemetery is a United States national cemetery, located in the Presidio of San Francisco, California. Because of the name and location, it is frequently confused with Golden Gate National Cemetery, a few miles south of the city. About 1937, San Francisco residents voted to no longer build cemeteries within the city proper and, as a result, the site for a new national cemetery was selected south of the city limits. The cemetery is one of only four officially existing within San Francisco city limits (the others being the Columbarium of San Francisco, the historic graveyard next to Mission Dolores, and the sarcophagus of Thomas Starr King).

The Presidio of San Francisco (originally, El Presidio Real de San Francisco or The Royal Fortress of Saint Francis) is a park and former U.S. Army post on the northern tip of the San Francisco Peninsula in San Francisco, California, and is part of the Golden Gate National Recreation Area. It had been a fortified location since September 17, 1776, when New Spain established the presidio to gain a foothold in Alta California and the San Francisco Bay. It passed to Mexico in 1820, which in turn passed it to the United States in 1848. As part of a 1989 military reduction program under the Base Realignment and Closure (BRAC) process, Congress voted to end the Presidio's status as an active military installation of the U.S. Army. On October 1, 1994, it was transferred to the National Park Service, ending 219 years of military use and beginning its next phase of mixed commercial and public use.In 1996, the United States Congress created the Presidio Trust to oversee and manage the interior 80% of the park's lands, with the National Park Service managing the coastal 20%. In a first-of-its-kind structure, Congress mandated that the Presidio Trust make the Presidio financially self-sufficient by 2013. The Presidio achieved the goal in 2005, eight years ahead of the scheduled deadline.The park has many wooded areas, hills, and scenic vistas overlooking the Golden Gate Bridge, San Francisco Bay, and the Pacific Ocean. It was recognized as a California Historical Landmark in 1933 and as a National Historic Landmark in 1962.

El Polín Spring is a natural spring in San Francisco, California located in the Presidio. It is the source of the central tributary of El Polín Creek (also called Tennessee Hollow Creek). The spring was used by the Ohlone people, the Spanish military, and the U.S. Army as a freshwater source. Much of the stream was channelized or placed in underground culverts, and many riparian areas were used for landfill. Beginning in the 2000s, the Presidio Trust has worked to rehabilitate El Polín spring and daylight sections of the creek downstream. In 2005, 77,000 tons of landfill were removed from Thompson Reach, a downstream section, and native riparian species were planted. In 2011, El Polín was restored, with new trails, native plants, and a picnic area installed.
