The East Bay Regional Park District comprises 73 parks and a system of interpark trails spanning over 125,000 acres in Alameda and Contra Costa counties. These parklands preserve the natural beauty that makes the Bay Area such a desirable place to live. They provide habitat for wildlife, including many rare and endangered species. They also enhance the region's quality of life, resulting in tangible economic benefits as well as aesthetic values. Whether you enjoy hiking, biking, fishing, swimming, nature programs, volunteer activities, or just relaxing in beautiful natural surroundings, there is a park for you.
Know before you go! View Alerts & Closures notices below before heading out to parks. Some trails, park areas, swim facilities, may be temporarily closed -- due to weather conditions, water/algae conditions, park projects, habitat restoration, or repairs and maintenance.
