About Annadel State Park

Annadel State Park is a popular destination for hikers and mountain bikers, located just east of Santa Rosa, California. The park offers a mix of shaded groves and open meadows alongside small lakes and dense woodlands, providing a dynamic environment for outdoor activities.

Wilderness Landscape & Natural Heritage

Annadel State Park, located in the heart of Sonoma County, California, encompasses over 5,000 acres of rolling hills, thick woodlands, and scenic meadows. The park, accessible from Santa Rosa, draws outdoor enthusiasts for its extensive network of trails popular with both hikers and mountain bikers. Lake Ilsanjo, nestled within the park's boundaries, offers respite for anglers looking to catch sunfish and bass. Historically, the region was home to Pomo and Wappo tribes before later serving as a quarry site in the late 19th and early 20th centuries. Today, remnants of its historical legacy can be seen in the form of old quarry pits. Annadel’s ecological appeal is characterized by its abundant wildflowers, which bloom prolifically in spring, as well as its diverse fauna, including deer and coyotes. The park serves as an ideal backdrop for leisurely picnics and nature photography, ensuring its popularity among a range of visitors.
