Windy Hill is named for its distinctive, breezy grass-covered hilltop, which can be seen from many areas of the peninsula. The 1,414-acre preserve features open grassland ridges and forests of redwood, fir, and oak.


Recognized as a significant addition to Midpen in 1980, Windy Hill Preserve was formed in the "upper" portion with a 537-acre acquisition with major support from the Peninsula Open Space Trust. A second major purchase of 429 acres in 1987 added the "lower" portion and included the scenic backdrop of Spring Ridge.

The Peninsula Open Space Trust, a local nonprofit land trust, provided major support for acquisition of this preserve.
