Wilderness Landscape & Natural Heritage
Rocky Ridge Open Space Preserve encompasses over 3,200 acres of hillside terrain in the Santa Cruz Mountains of San Mateo County, California. Characterized by steep rocky ridges and chaparral-dominated landscapes, this preserve provides visitors with panoramic views of the Pacific Ocean to the west and the San Francisco Bay Area to the east on clear days. The preserve’s diverse ecosystems feature coastal scrub, grasslands, oak woodlands, and occasional stands of Douglas fir, providing habitat for a variety of wildlife including bobcats, deer, and numerous bird species. Historically, the area was part of Mexican land grants and later used for grazing before being acquired by the Midpeninsula Regional Open Space District in the late 20th century to protect it from development. Key recreational opportunities include multi-use trails suitable for hiking, mountain biking, and equestrian activities. Visitors are drawn to the challenging climbs, especially via the Rocky Ridge Trail, and the rewarding scenic vistas from the preserve’s highest points. The preserve has no developed facilities or campgrounds, emphasizing a more primitive outdoor experience. Its remote feel and relatively lower visitor traffic compared to nearby parks contribute to a more solitary natural experience. Rocky Ridge Open Space Preserve appeals to outdoor enthusiasts looking for strenuous exercise, nature observation, and impressive ridge-top panoramas within easy reach of the Bay Area.
