The Windy Hill Open Space Preserve is named so for the distinctively breezy and grass-covered hilltop, a site that can be spotted from several areas around the peninsula. The open preserve is spread out across 1,335 acres and consists of forests of oak, fir, and redwood and ridges of open grassland. Windy Hill is a perfect place for anyone who likes to fly kites and leashed dogs are permitted on all of the trails with the exception of the Razorback and Lost Trails. There is also limited equestrian and bike access on trails, and picnic tables available.
