Just upstream from the Carbon Canyon Dam, you'll find the 175 glorious acres that make up Yorba Regional Park. This accommodating place, formerly a cattle ranch, is now a perfect spot for a family picnic. Nature trails for hiking abound, along with separate equestrian trails and a paved bike path, which is much easier for little bicyclists to navigate than dirt trails. The terrain is made up of rolling foothills, with native coastal plants and wildlife. Don't miss a truly magnificent 10-acre stand of Coastal Redwoods while you're hiking or biking around. Picnic shelters are large, shady and equipped with barbecue grills, so bring a little charcoal along with those franks and burgers. The lakes here are stocked and fishing is permitted with a license.
