Windy Hill is named for its distinctive, breezy grass-covered hilltop, which can be seen from many areas of the peninsula. The 1,335-acre preserve features open grassland ridges and forests of redwood, fir, and oak.

Peninsula Open Space Trust, a local non-profit land trust, provided major support for acquisition of this preserve.
