On 806 acres, only a short distance from the San Ramon Valley subdivisions, Bishop Ranch Open Space Regional Preserve provides peace and solitude. Deer, red-tailed hawks, and turkey vultures are among the species to keep an eye out for.

Recreational Events in the Park

Some of the activities accessible on this ridge-top refuge include hiking, kite flying, and blanket picnicking. Aside from a trailhead and trails, there are no other services.

Park Accessibility

The trails are usually not suitable for wheelchair users due to steep grades.


To get to the park, take I-680 west to Bollinger Canyon Road in San Ramon and then west to San Ramon Valley Boulevard. Drive to Morgan Drive by turning left (south) on San Ramon Valley Boulevard. On Morgan Drive, turn right (west) and go a short distance. The trailhead is on the left side of Morgan Drive.


Bishop Ranch Regional Preserve (BRRP), also known as Bishop Ranch Regional Open Space Preserve, is a 444-acre (1.80 km2) regional park situated on a ridgetop near San Ramon, California. It's west of San Ramon Valley Road and south of Bollinger Canyon Road, in a suburban area. There are no amenities other than a trailhead, and the trails are steep. The East Bay Regional Parks system contains it.

The Bishop Ranch Preserve is mainly used for nature observation. There are three hiking, walking, and horseback riding trails, but no picnicking or camping facilities. The steep terrain makes the trails unsuitable for wheelchairs in most situations.

EBRPD reported in August 2015 that it had purchased a 362 acre (1.46 km2) tract along the Calaveras Ridge, which will be added to BRRP and will connect Bishop Ranch and Dublin Hills Regional Park. This purchase, according to EBRPD board member Beverly Lane, "is part of an EBRPD initiative to create a continuous trail that will extend from Sunol to Lafayette via six regional parks." The property was previously owned by the Wiedemann family, who had been raising cattle here since the 1860s and paid $2 million for it. Harlan Hill, a local landmark that rises to a height of 1,719 feet, is part of the new addition (524 m). Before EBRPD can open this new acquisition to the public, it must complete a land-use plan for the Bishop Ranch open space.
