The East Bay Regional Park District (EBRPD) is a special district operating in Alameda County and Contra Costa County, California, within the East Bay area of the San Francisco Bay Area. It maintains and operates a system of regional parks which is the largest urban regional park district in the United States. The administrative office is located in Oakland. As of 2020, EBRPD spans 124,909 acres (50,549 ha) with 73 parks and over 1,330 miles (2,140 km) of trails. Some of these parks are wilderness areas; others include a variety of visitor attractions, with opportunities for swimming, boating and camping. The trails are frequently used for non-motorized transportation such as biking, hiking, and horse riding. More than 200 miles (320 km) of paved trails (identified as Interpark Regional Trails) through urban areas link the parks together. From Wikipedia
