The Midpeninsula Regional Open Space District preserves more than 70,000 acres with roughly 250 miles of trails, while the Santa Clara Valley Open Space Authority manages preserves that are free to visit year-round and support hiking, mountain biking, horseback riding, and environmental education.
This guide covers the best parks, preserves, and open spaces across the full Silicon Valley footprint — from iconic destinations like Rancho San Antonio Preserve and Fremont Older Open Space Preserve to city favorites and lesser-known local gems across San Jose, Palo Alto, Mountain View, Cupertino, Sunnyvale, Santa Clara, Los Gatos, Saratoga, Campbell, Milpitas, Fremont, Menlo Park, Los Altos, and Redwood City.
