Overview
Monte Bello Open Space Preserve is a 2,800-acre protected landscape managed by the Midpeninsula Regional Open Space District (MROSD), situated in the Santa Cruz Mountains above the towns of Los Altos Hills and Cupertino in Santa Clara County. The preserve occupies a ridge that runs roughly parallel to the San Andreas Fault, and this geological identity shapes much of what visitors experience here — from the rolling topography to the diverse plant communities that shift with elevation and aspect.
The preserve is best known for its commanding views from Black Mountain (elevation approximately 2,800 feet), its mixed woodland of oak, madrone, and bay laurel, and the upper headwaters of Stevens Creek, which support riparian habitat and a remnant old-growth redwood grove. It connects directly to the adjacent Stevens Creek County Park below, creating a much larger continuous natural corridor.
Monte Bello draws hikers, mountain bikers, and nature photographers from across the Bay Area. Because it sits above the Silicon Valley smog layer, clear days offer visibility stretching to Mount Diablo, the Diablo Range, and the Santa Cruz Mountains ridge. The preserve is strictly non-commercial — there are no food vendors, lodging, or retail on site.
Before You Go
Entry and Permits
The preserve is free to enter and open to the public. No reservation or permit is required for general day use. Verify current hours and any seasonal closures on the official MROSD website (openspace.org) before visiting, as conditions and access points can change after wet winters or fire risk periods.
What to Bring
- Ample water — there is no potable water available at the trailheads or on the ridge
- Sunscreen and layers; the ridge is exposed and temperatures can drop sharply in afternoon wind
- Trail map (downloadable from the MROSD site or available at some trailhead kiosks)
- Sturdy footwear; many trails involve significant elevation gain and rocky terrain
- Snacks for full-day hikes — no food is sold on site
Dogs and Bikes
Dogs are not permitted in Monte Bello Open Space Preserve. Mountain biking is allowed on designated trails only; check the MROSD trail use map carefully before planning a bike-specific visit. Cyclists and hikers share certain multi-use corridors, so awareness and courtesy are expected.
Getting There
By Car
The primary trailhead and parking area is located off Page Mill Road, above Palo Alto. The road is narrow, winding, and gains elevation rapidly — allow extra time and drive carefully, especially on weekends when traffic can back up. A second access point exists near the Monte Bello Road area; verify current trailhead availability with MROSD before visiting. Parking lots fill early on weekend mornings in spring and fall.
By Public Transit
Public transit access is limited. The preserve sits at high elevation on a rural road not regularly served by local bus routes. Most visitors arrive by private vehicle. Carpooling is strongly encouraged given limited parking. Verify whether any seasonal shuttle services operate in a given year with Santa Clara Valley Transportation Authority (VTA) or MROSD directly.
From Major Hubs
The preserve is roughly 15–20 miles from downtown Palo Alto and approximately 50 miles from San Francisco. San Jose Mineta International Airport (SJC) and San Francisco International Airport (SFO) are the closest major airports, both within a reasonable drive, though a rental car or rideshare will be needed to reach the preserve.
Getting Around
All travel within the preserve is on foot or by bicycle (where permitted). There is no internal shuttle or motorized access beyond the parking areas. The trail network is well-signed at major junctions, but carrying a printed or downloaded map is recommended because mobile signal can be unreliable at elevation.
The main ridge trail to Black Mountain is the backbone of the network. Side trails branch into the Stevens Creek drainage toward the redwood grove, making loop routes possible and rewarding. Total elevation gain for a summit-and-return circuit can exceed 1,500 feet depending on your starting point, so assess your fitness honestly before committing to longer loops.
Things to See & Do
Hiking
Hiking is the primary activity. The trail to Black Mountain summit offers panoramic Bay Area views and is the most popular objective. The Canyon Trail descends into the redwood grove along Stevens Creek and provides a strong contrast to the exposed ridge — cool, shaded, and botanically rich. Loop combinations of varying lengths suit both casual walkers and experienced hikers.
Wildlife and Nature Observation
The preserve supports a notable diversity of wildlife including mule deer, coyote, red-tailed hawk, wild turkey, and various raptor species. Spring wildflowers on the grassy ridgelines include California poppies, lupine, and blue-eyed grass. The riparian zone along Stevens Creek hosts songbirds and occasional sightings of newts in wet months.
Photography
The ridge offers some of the clearest and most expansive views of the Santa Clara Valley available from public land. Early morning and late afternoon light are particularly favorable. The redwood grove and creek corridor offer entirely different compositional opportunities in softer, filtered light.
Mountain Biking
Designated multi-use trails within the preserve allow mountain biking. The terrain is challenging and technical in places. Riders should consult the current MROSD trail use map to confirm which segments are open to bikes, as regulations can be updated.
Practical Information
Restrooms
Vault toilets are available at the main Page Mill Road trailhead. There are no restroom facilities within the trail network itself.
Connectivity
Mobile phone signal is unreliable throughout much of the preserve, particularly in the canyon areas. Download offline maps before arriving.
Leave No Trace
The preserve is a protected natural area. Pack out all trash, stay on designated trails, and do not pick plants or disturb wildlife. Fires and smoking are prohibited throughout the preserve.
Accessibility
The terrain is largely rugged and not wheelchair accessible. Contact MROSD directly to ask about any accessible segments near trailheads.
Emergency Contact
In a true emergency, call 911. Cell coverage may be limited; inform someone of your plans before visiting remote areas. MROSD Ranger patrols operate within the preserve on a regular basis.
Safety
Mountain lion activity has been recorded in the Santa Cruz Mountains, including the Monte Bello area. The risk of an encounter is very low, but hikers should remain aware of their surroundings, avoid hiking alone in remote areas, and know the standard advice: do not run, make yourself appear large, and make noise. MROSD posts current wildlife advisories at trailhead kiosks and on their website.
The San Andreas Fault runs through the preserve. While this does not pose a day-to-day hazard, it is worth knowing if you are curious about the terrain's character. Rattlesnakes are native to this region and may be encountered on warm days, particularly on sunny, rocky sections of trail. Watch where you step and place your hands.
Weather on the ridge can change rapidly. Morning fog common in the Bay Area can reduce visibility significantly. Afternoon winds are often strong. Layer appropriately and check the forecast for the specific elevation band (near 2,500–2,800 feet) rather than valley forecasts, which will not reflect ridge conditions accurately.
