Enjoy a four-mile loop trail around the newly opened Mangini Ranch Educational Preserve, which includes 207.8 acres situated between the Crystyl Ranch residential development in Concord and Lime Ridge Open Space in Walnut Creek.

 The preserve includes grassland, stream canyons, blue oak woodland, chaparral, and oak savannas. It’s home to rare species such as the northernmost stand of desert olive, Hospital Canyon larkspur, and threatened Alameda whipsnake. Deer, coyotes, burrowing owls, kestrels, and lots of other wildlife live here too.
