Rancho San Antonio County Park and Open Space Preserve
Although it seems like one park, Rancho San Antonio is actually two parks: the 165-acre County Park and the adjoining 3,988-acre Open Space Preserve. The combined Rancho San Antonio, known to locals simply as "Rancho", is one of the most accessible trail running parks in the Bay Area due to its well-maintained and well-marked trails and its close proximity to I-280 and I-85. Rancho is a great place for a beginner or advanced trail runner to experience the joy of trail running. There are many trails in the park so you can create anything from a short run to an epic 15+ mile loop to Black Mountain. Rancho also connects to Monte Bello Open Space Preserve via the Black Mountain Trail so you can do even longer multi-park runs. Elevations in the park range from about 400' at the entrance to over 2800' at Black Mountain, and the climbs range from moderate to difficult.
There are a few different trailheads at Rancho. The main parking area and trailhead is off of Cristo Rey Drive in Cupertino. There are bathrooms and drinking fountains at the main entrance. In addition, there is "back entrance" with a smaller parking area and trailhead off Rhus Ridge Road in Los Altos Hills. There is only parking for about 10 cars here, and no bathrooms or water. This trailhead provides the most direct access to the Black Mountain Trail; however, be prepared for 600 feet of climbing in the first mile!
All of the Favorite Runs on this page start at the main parking area near the bathrooms. After driving through the main park entrance, stay to your right and follow the twisty road all of the way to where it ends in the main parking lot. You will know you are there when you see the bathrooms.
In addition to great trails, Rancho San Antonio is also the home to Deer Hollow Farm, a real working farm with cows, pigs, goats, sheep, chickens, other animals, and an organic garden as well as numerous turn-of-the-century ranch buildings. An additional attraction is the restored Grant Cabin, furnished to represent living conditions in the late 1800s. The farm offers tours, classes, special events, and camps for children. Please refer to the Deer Hollow Farm page for more info.

Favorite Run #3: Power Poles (8.4 mi, ~1700 feet elevation gain)
|
The "Power Poles" trail (officially called the PG&E Trail) is a fire road that was built by PG&E up the steep walls of the canyon to run power lines all of the way up to Skyline Blvd. The trail is pretty steep in places but gives you a great workout when you want to get the maximum workout in the minimum time! The route as described here is an out-and-back, but you can make it into a loop by climbing PG&E Trail and then taking High Meadow Trail back down from the top of PG&E.
Start this run by heading across the wooden bridge at the northwest corner of the north parking lot (the bridge by the stretching bars). GPX Track Printable Trail Map Driving Directions |

Favorite Run #4: Quarry Trail Figure-8 (13.3 mi, ~2200 feet elevation gain)
|
This is a great loop that covers most of Rancho San Antonio Open Space Preserve. This run starts out with a gentle climb past the farm, and the climb then gets progressively steeper as you go. The last mile or so on the Quarry Trail has some extremely steep sections. However, you are rewarded with some spectacular views from the Quarry Trail followed by a 6-mile decent on the awesome singletrack Black Mountain Trail and Chamise Trail.
