We'll have to double-check with Webster, but we're pretty sure feeding a flock of ducks by a lake is pretty much the definition of leisure. It's one of the many activities you can get in on at Yorba Regional Park. Situated at the mouth of Santa Ana Canyon, this mile-long expanse of lush grass, serene lakes, softball diamonds, modern playgrounds and bike trails is one of the few things about the eastern end of Anaheim that helps cultivate the identity of one of the most delightfully slow-paced areas of OC. Among its biggest draws are its diverse stable of rental bikes, paddle boats (yes, you can actually get out on the water!) and Big Wheels for the kids. Local school troops and party planners get plenty of use out of this local haven for daytime diversions, and the huge shade trees, gazebos and barbecue pits make this an easy place to bring people together.
