About Keller Regional Park

Keller Regional Park is a scenic recreation area in San Joaquin County offering a combination of forested trails, a freshwater lake, and picnic facilities, ideal for hiking, fishing, and family outings.

Wilderness Landscape & Natural Heritage

Keller Regional Park, located in the Sierra Nevada foothills near Lodi, California, encompasses over 500 acres of natural landscapes with rolling hills, oak woodlands, and riparian habitats surrounding a central 120-acre reservoir. The park was developed and opened in the mid-20th century as a regional outdoor recreation facility managed by the San Joaquin County Parks Department. Its topography features mixed evergreen and deciduous trees, providing habitat for various native wildlife including deer, hawks, and waterfowl. The reservoir supports warm-water fishing with species such as bass, catfish, and bluegill. Visitors can explore nearly 10 miles of well-maintained hiking and biking trails ranging from easy lakeside strolls to more challenging routes through upland terrain. The park is a popular destination for picnicking, boating, and wildlife observation, offering multiple picnic areas, a boat launch, restrooms, and playgrounds. Keller Regional Park serves local communities as a convenient natural getaway that combines water recreation with forested trails. It also plays a role in watershed management and environmental education programs led by area schools and community groups. The park’s accessibility and range of moderate outdoor opportunities make it a favored spot for family recreation and outdoor enthusiasts seeking a versatile day-use area within driving distance of the Central Valley.
