Redwood Regional Park 7867 Redwood Rd. Weekend parking & dog fee. This unassuming 1,830-acre park is full of surprises. It holds a grove of second-growth redwood trees that are 150 years old and older—a remnant of the solid old-growth redwood forest found here in Oakland long ago, which was harvested to build homes in San Francisco after the Gold Rush--and has the only fish ladder in the Bay Area where rainbow trout spawn (the fishway interpretive site is just inside the main park entrance off Redwood Road). The popular Stream Trail that follows Redwood Creek is mostly paved.
