The park contains the Guajome Adobe, a National Historic Landmark constructed in the 1850s using traditional sun-dried mud bricks.
The park's name originates from the Luiseño word 'qawaxami,' meaning 'frog pond.'
The park is situated on a former Mexican land grant known as Rancho Guajome.
The wetlands provide a protected habitat for the endangered least Bell's vireo bird species.
The park features a unique combination of five distinct plant communities, ranging from freshwater marsh to southern willow scrub.
Guajome Regional Park covers 557 acres of diverse ecosystems, including wetlands, woodlands, and grasslands. The park is anchored by Guajome Lake, a primary water feature that attracts numerous migratory bird species throughout the year. Visitors can navigate 4.5 miles of multi-use trails suitable for hiking, horseback riding, and mountain biking. The park offers 33 electric and water campsites, alongside equestrian-friendly campsites. The historic Guajome Adobe, an 1850s Mexican-era ranch house, is located within the park grounds and is listed on the National Register of Historic Places. The terrain encompasses coastal sage scrub and riparian habitats, providing significant local biodiversity. Park facilities include multiple picnic areas, playgrounds, and an amphitheater.
