Mount Stakes, Mountain summit in Diablo Range, California, US.

Mount Stakes is a mountain summit in the Diablo Range between Santa Clara and Stanislaus counties in California. The peak stands at approximately 3,810 feet and offers views across the surrounding valleys and ridges.

The mountain has served as a geographic boundary between Santa Clara and Stanislaus counties since the 19th century. This location at a county line has shaped the area since both jurisdictions were established.

Mount Stakes is the highest point in Stanislaus County, which makes it a target for hikers working through California county high points. The summit sits on the Santa Clara–Stanislaus county line, less than a mile north of Henry W. Coe State Park, so the county-line position is part of what draws peak baggers.

Access is through Henry Coe State Park with a lengthy round-trip hike from Bell Station Gate. On certain April weekends, limited vehicle access into the park reduces the walking distance significantly.

Mount Stakes is the highest point in Stanislaus County, a fact that draws county-highpoint collectors. The summit lies less than a mile north of Henry W. Coe State Park and receives some snow in winter.
