San Diego Natural History Museum
About
Founded in 1874 as the San Diego Society of Natural History, this is the oldest scientific institution in Southern California and the second-oldest west of the Mississippi River. Its permanent home in Balboa Park opened in 1933, and a major expansion in 2001 more than doubled the building's size, adding a postmodern facade and glass atrium.
The museum's research collections include hundreds of thousands of insect and reptile specimens, millions of marine invertebrates, and extensive fossil holdings tied to its long-running Fossil Mysteries exhibit on the region's prehistory. A newer Paleontology Center added in 2025 continues the museum's original focus on documenting the natural history of California and Baja California specifically, rather than the world in general.
Because the exhibits center on the plants, animals, and geology of this specific binational region, they can double as an introduction to the local landscape for a family that just arrived and has not yet had the chance to explore the desert, coast, or mountains nearby in person.
