About

El Sereno Open Space Preserve offers breathtaking vistas and expansive trails in the Santa Cruz Mountains. Part of the Midpeninsula Regional Open Space District, this 1,614-acre preserve rises from rolling foothills to the majestic 2,500-foot Mount El Sereno. It serves as a vital natural escape, showcasing California's diverse ecosystems and offering a serene backdrop to the bustling Silicon Valley below.

The preserve boasts approximately seven miles of multi-use trails, welcoming hikers, mountain bikers, horseback riders, and dog walkers. These trails wind through vibrant chaparral communities, sun-drenched meadows, and occasional shaded areas near creeks. Along your journey, you'll encounter a rich tapestry of native California plants such as fragrant California bay laurel, resilient chamise, widespread coyote bush, and the distinctive yerba santa. Keep an eye out for diverse manzanita and ceanothus varieties, as well as the unique California coffeeberry.

Visiting El Sereno Open Space Preserve is an opportunity to immerse yourself in nature and witness some of the region's most spectacular scenery. On clear days, the ridgelines provide sweeping panoramic views of Silicon Valley, the serene Lexington Reservoir, and the distant Sierra Azul and St. Joseph's Hill Open Space Preserves; some fortunate visitors might even glimpse the Monterey Peninsula. Beyond the views, the preserve is home to local wildlife, including mule deer, coyotes, gopher snakes, and brush rabbits, making every visit a chance for a memorable encounter with the natural world. Don't forget to bring the Snappit nature identification app along to scan local species.

El Sereno Open Space Preserve holds a significant place in the conservation efforts of the Midpeninsula Regional Open Space District, which acquired the land in 1975, making it one of the organization's oldest preserves. In a continued commitment to expanding public access and preserving natural connections, Midpen partnered with the Peninsula Open Space Trust in 2020-2021 to acquire an additional 182 acres. This crucial expansion linked two segments of the Aquinas Trail, integrating it into the broader Bay Area Ridge Trail network and enhancing the preserve's connectivity. To honor his dedication to open space, a commemorative bench for State Senator Jim Beall was installed along the Aquinas Trail in December 2020, offering a scenic spot overlooking Lexington Reservoir and San Jose.

Carry a map

Although trails are generally well-maintained, carrying a map is advisable, as signage can be minimal in some areas.

Arrive early for parking

Parking is very limited at trailheads, particularly at Montevina Road, so arriving early, especially on weekends, is recommended. Some specific parking areas might require a permit.
