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. Picnic tables are located adjacent to the Spring Ridge parking area — a super beginning to a day, or the perfect ending to a long hike!

Windy Hill is an ideal spot for kite flying. Hang gliding, paragliding, and remote control gliding are allowed by obtaining a special activity permit. Please see Permit Information for more information.

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.
