Pinnacles National Park is the southernmost park in the San Francisco Bay Area Network, covering about 27,000 acres at the southern end of the Gabilan Mountains. Ancient volcanic activity and subsequent erosion formed its namesake rock spires, cliffs, and talus caves. The park also protects a rare broadleaf chaparral ecoregion.

Due to its unique resources, Pinnacles National Park supports a rich community of flora and fauna. It hosts one of the highest densities of breeding prairie falcon populations in North America and has the highest bee diversity per unit area known in the world.

Encroachment of exotic species, climate change, fire management, and recreation management are top natural resource concerns for the park.
