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 100-foot-tall 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. One section of redwoods that is most spectacular is the old-growth navigation trees that were used by ships to navigate the bay. Located near the Madrone Picnic Area at nearby Roberts Recreational Area, it holds a monument and some of the largest redwoods. The park also 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 park is also known as a gathering spot for hibernating ladybugs in the winter. The densest congregation is usually around the junction of the Stream and Prince trails. The popular Stream Trail that follows Redwood Creek is partially paved.
