Morgan Territory Regional Preserve

Sandstone hills within the park's 5,321 acres are adorned in spring with more than 90 species of wildflowers, including the Diablo sunflower (Helianthella castanea), which grows only in the foothills of Mount Diablo. Deer, coyote and even the elusive mountain lion may be seen here, and a variety of raptors frequently soar overhead.

Expansive ridgetop views reveal Mount Diablo to the west, Mount St. Helena to the north and the snow-covered Sierra to the east. Lowland valleys cradle the headwaters of Marsh Creek.

Park activities include hiking, horseback riding, picnicking and camping. There is a backpack campsite in the Regional Preserve. Reservation is required to use the campsite. To make a reservation, call 1-888-EBPARKS or 1-888-327-2757, press option 2.
