Overview

Rancho San Antonio County Park & Open Space Preserve offers visitors a unique experience with a sampling of diverse environments, interesting cultural history and a variety of activities. The area features over 24 miles of trail throughout the 3,988-acre open space preserve and adjoining 165-acre county park.

Bike and Equestrian Access Limited: Activities may not be designated on all trails within the preserve -- refer to the map and trail signage for where each activity is permitted.

Temporary COVID-19 Restrictions

  • Face coverings are required when you can’t stay 6 feet away from persons you don’t live with. Many Midpen trails are narrow — wear a mask, bandanna or gaiter you can pull over your mouth and nose as needed.
  • Paper maps are not available at preserves. Please download a map before leaving home or snap a photo of the signboard map before you hike.
  • One-way routes are in place on some trails, download preserve map for information.

Please Be Alert

If you see a mountain lion do not run; slowly back away, leave the area and report the sighting to a Midpen ranger at 650-691-2165.

Mountain lions in California face many challenges. They need large habitats, and because their native territories in the Santa Cruz Mountains have become hemmed in by roads and development, some mountain lions inhabit areas of open space near the wildland-urban interface. As a top-level predator, mountain lions play an important role our local ecosystem and projects like the Midpen Highway 17 Wildlife and Trail Crossings are critical to keeping wildlife populations safe and healthy.

Features

Rancho San Antonio County Park is managed by Midpen through an operations and management agreement with the Santa Clara County Parks and Recreation Department. Together, Rancho San Antonio County Park & Open Space Preserve provide diverse recreational opportunities. 

Rancho County Park

At Rancho San Antonio County Park, the most popular activities are jogging and hiking. Stretching bars are available at the restroom parking area and equestrian staging area. The park provides hiking, bicycling and equestrian trails, which connect with additional trails within the open space preserve. Bicycles are restricted to designated trails only, and are not permitted west of Deer Hollow Farm. Similarly, equestrians are limited to the equestrian staging area and Coyote Trail, within the county park. 

The South Meadow area, located in the county park and adjacent to the parking areas, provides opportunities for informal play on a "rough grass" area. The equestrian staging area, which includes a horse-watering trough, is located adjacent to the South Meadow. Nongas-powered model airplane enthusiasts use a staging area adjacent to the parking lots near the park entrance for takeoffs and landings and fly their aircraft above the South Meadow area. Download model airplane rules here. Please note that during red flag warnings the model aircraft area will be closed.

The North Meadow area, across Permanente Creek from the parking and staging areas, provides an informal irrigated meadow grass play area. The North Meadow includes a small number of picnic tables and barbecues. The picnic area is on a first-come, first-serve basis and the maximum group size for the area is 25 people. Please note that during red flag warnings the barbecue area will be closed.

 

Open Space Preserve

The preserve's extensive 24 miles of trails are available for exploration, whether one chooses to hike (dogs, however, are NOT permitted), bike, or horseback ride. Trails can be combined to form loops of different lengths and difficulties including the 3-mile Wildcat Loop Trail and the 4-mile Black Mountain Trail, To get to the northern part of the preserve from the valley floor, take the 2.1-mile Chamise Trail, which ascends gradually to a tranquil, secluded meadow in the Duveneck Windmill Pasture Area. This was once the location of a picturesque windmill from former ranch days when cattle freely roamed the hillsides. Visitors can now picnic amid fields of grass in the shadow of Monte Bello Ridge and Black Mountain. A major part of this area was a gift from Frank and Josephine Duveneck, and adjoins Hidden Villa Ranch, a non-profit environmental education facility.

A highlight of the preserve is Deer Hollow Farm, a working farm with turn-of-the-century ranch buildings, an organic garden and a cow, pigs, goats, sheep, chickens and other animals. An additional attraction is the restored Grant Cabin, furnished to represent living conditions in the late 1800s.

How to Get Here

Parking at the preserve can be congested at busy times. Bicycling, walking, use of ride apps or public transportation are encouraged.  Or, take the NEW Via-Cupertino Shuttle—an on-demand shuttle service providing transportation anywhere in Cupertino and to Sunnyvale Caltrain!

 

Driving directions From I-280 (north or south):

  • Take the Foothill Boulevard exit and proceed south on Foothill Boulevard approximately 0.2-mile to Cristo Rey Drive.
  • Turn right on Cristo Rey Drive, continue for about 1 mile, veer right around the traffic circle, and turn left into the County Park entrance.
  • There are several parking lots, including one designated for equestrian trailers. The trailhead for the preserve is located adjacent to the 85-car parking area in the northwest lot.

Trails

This preserve's extensive 24 miles of trails are available for exploration, whether one chooses to hike (dogs, however, are NOT permitted), bike or horseback ride. Trails can be combined to form loops of different lengths and difficulties.

Bike and Equestrian Access Limited: Activities may not be designated on all trails within the Preserve -- refer to the map and trail signage for where the activity is permitted. 

Wildcat Loop Trail – 3.0 miles - A popular route for hikers and joggers, the trail follows a creek into a cool, fern-walled narrow canyon, ascends through chaparral to open meadows on the middle ridge, and loops back to Deer Hollow Farm. Lupine, poppies and patches of blue-eyed grass bloom in the meadows in spring. Visitors can pause or picnic here and, on a clear day, enjoy spectacular views of Mt. Tamalpais to the north and Mt. Hamilton to the east.

Black Mountain Trail - (4.0 mi) The trail climbs through chaparral, grassland, and oak woodland to the top of Black Mountain. Steep canyons and narrow ridges can be seen from various points. At the top of 2,800-foot Black Mountain, there are other views west into Stevens Creek Canyon and open space lands along Skyline Ridge, as well as across Santa Clara Valley.

Stephen E. Abbors Trail - (3.7 mi) A more challenging Trail with 1600 ft elevation gain, follows the path of electrical towers up Black Mountain. Hikers are rewarded with great views of the bay area and western foothills. Combine with some of the other trails Wildcat Canyon or Upper High Meadow Trails for a longer loop. (formerly PG & E Trail)

To get to the northern part of the preserve from the valley floor, take the 2.1-mile Chamise Trail, which ascends gradually to a tranquil, secluded meadow in the Duveneck Windmill Pasture Area. This was once the location of a picturesque windmill from former ranch days when cattle freely roamed the hillsides. Visitors can now picnic amid fields of grass in the shadow of Monte Bello Ridge and Black Mountain. A major part of this area was a gift from Frank and Josephine Duveneck, and adjoins Hidden Villa Ranch, a non-profit environmental education facility.

History

The Ohlone Indians lived in the Rancho San Antonio area for over 3,000 years prior to the arrival of the Europeans. A large village, known as Partacsi, was located in this general area. An expedition led by Colonel Juan Baptista de Anza passed through this area in March of 1776. Mission Santa Clara de Asis was founded in October of the same year. In 1822, Mexico became independent and the Secularization Act stripped the missions of their holdings. After 1833, land grants were mainly given to army veterans and many ranchos were established. The chief commercial products of the ranchos were cattle hides and tallow. Governor Alvarado granted Rancho San Antonio to Juan Prado Mesa in 1839. This 440-acre rancho was bounded by Adobe Creek to the north and Stevens Creek to the south, and included Permanente Creek. Mesa had been a soldier at the San Francisco Presidio since 1828, served as a corporal in the Santa Clara Guard. Mesa died in 1845. California became part of the United States in 1848 and all land grants issued by the Mexican government became subject to review under U.S. law.

In 1853, William Dana, a former seafarer and merchant, purchased the Rancho. During this time the original Mexican land grants were challenged and six persons laid claim to the Rancho. Two of the claims were patented by the United States in 1857, with Dana retaining 3,542 acres. In 1861, John and Martha Snyder purchased 850 acres of the original Rancho San Antonio lands on Permanente Creek. The Snyder's grain crop of 1862 was the first raised without irrigation in this area of the county and was so successful that it inspired others. The Snyder's had about 500 acres under cultivation, including a 16-acre vineyard with a large winery and 25 acres in orchard. John Snyder, born in 1828 in Indiana, arrived in Santa Clara County in 1850 where he was employed on local farms. In 1855, he married Martha Kifer. John died in 1901 and his wife continued to live on the ranch until her death in 1919.

In 1923, the Catholic Church purchased the Snyder Ranch and in 1926 constructed Saint Joseph's Seminary and the Maryknoll Seminary. St. Joseph's was badly damaged in the 1989 earthquake and was subsequently demolished. The Maryknoll Seminary, with its oriental motif, stands east of the park across Cristo Rey Drive. The Santa Clara County Parks Department purchased 130 acres in 1977 and another 35 acres in 1981 from St. Joseph's Seminary. The county park improvements were constructed in the early 1980s, with additional improvements completed in 1993.
