![]() | FoothillsOpen Space Preserve - California |
This tiny 212-acre gem's steep and forested ravines form part of the Adobe Creek watershed above Hidden Villa Ranch and are adjacent to Palo Alto's Foothills Park.
Here you'll find a grassy ridgetop surrounded by steep chaparral covered slopes, with oak-madrone woodland in the ravines and on the north facing slopes.
