About San Juan Open Space Preserve

San Juan Open Space Preserve offers 1,100 acres of protected natural habitat with a network of trails ideal for hiking, trail running, and wildlife viewing just outside the urban areas of Morgan Hill.

Wilderness Landscape & Natural Heritage

San Juan Open Space Preserve is located in Santa Clara County, California, southeast of Morgan Hill. The preserve spans over 1,100 acres of rolling foothills, grasslands, and oak woodlands, providing habitat for a variety of native wildlife including deer, coyotes, raptors, and numerous songbirds. The preserve is part of the Midpeninsula Regional Open Space District and was acquired to protect open land from development while offering public access to outdoor recreational activities. Visitors can explore multi-use trails that are popular with hikers, trail runners, and equestrians. The preserve’s gentle terrain combined with sweeping views of the surrounding hills and distant mountain ranges makes it an excellent destination for casual day outings. Access points include the main entrance along San Juan Road, with trailheads connecting to nearby parklands and open spaces. The area has a Mediterranean climate with dry summers and mild, wet winters, supporting oak groves and native grasses. Historical use of the land includes grazing and small rural farms, but conservation efforts have focused on ecological restoration and fire prevention. Wildlife enthusiasts have opportunities to observe native species as the preserve acts as an important wildlife corridor in a rapidly urbanizing region. The preserve's management emphasizes low-impact recreation and maintaining the natural character of the landscape, making it a valuable resource for residents and visitors who want to experience nature close to Silicon Valley.
