At 2,812 feet, Black Mountain looms large, way up, and behind, the smaller hills to the west of Highway 280 in Silicon Valley.
It’s at the top-left of the park map, and is accessed from Rhus Ridge Road, off of Moody Road.
Last, but not least, is to get a permit (and gate code) to park on upper Montebello Road, from the Midpeninsula Open Space folks (“Waterwheel Parking” permit application).
The park map shows both the parking lot, and Black Mountain, on the right side.
