IT'S HARD TO BELIEVE that more than a century ago, this wild and rugged foothill country was full of miners with picks carving out some 150 miles worth of coal mining tunnels. This hike explores jagged and jumbled ridges, erratically sloped grasslands, and sprawling valleys, all dotted with blue oaks and patches of chaparral. This is remote land where the prairie falcon soars and coyote still howls at night, out of sight and sound of cars and houses.

Elevation: 2000+ft.

The Preserve's 42 miles of trails traverse areas of grassland, foothill woodland, mixed evergreen forest, chaparral, stream vegetation and exotic plantings. Notable among the latter are several tree species introduced by the coal miners. These include the black locust, pepper tree, almond, eucalyptus and tree of heaven.
Black Diamond is noted as the northernmost location of Coulter Pine, Black Sage, Desert Olive and Dudleya. In addition, several species that are restricted to the Mt. Diablo area occur here, including the Mt. Diablo Globe Lily, Mt. Diablo Helianthella and Mt. Diablo Manzanita. In the SPRINGTIME, the hills are covered with some of the most REMARKABLE wildflower displays in the Bay Area.

Black Diamond supports a healthy wildlife population. Coyotes and snakes are commonly seen. Mountain lions, bobcats, foxes and deer are occasionally spotted, while birds of prey soar overhead. Over 100 species of birds have been seen, from the rare golden eagle to the ever-present meadowlark.
The side-blotched lizard has its northern limit in the Preserve, and one rare animal species has been found here--the Alameda Whipsnake.

If you have a ride to offer or need a ride state so in your RSVP or use the discussion board.

    What trail are we taking? I'm very familiar with this terrain. I hike here all the time.
