Hiddenbrooke Open Space
These rolling grasslands offer expansive views of San Francisco, San Pablo, and Suisun Bays and the mountains that encircle them, from Mount Tamalpais to Mount Diablo. You have short steep climbs along this exposed trail and must return to Hiddenbrooke Parkway. During summer, take this trip on cool mornings; some spots are muddy after heavy rains.
