Deer Hollow farm is a working homestead farm operated for educational purposes in the park. 

The farm is operated by the City of Mountain View Recreation Division and is located about a mile from the main parking lot (see the map). As said before, the farm is a educational center and provides visitors, schools, and community groups a place to observe and even participate in farm life. The farm also has a short self guided tour available for visitors, and the live stock can be viewed at any time, if the animals are feeling friendly. The farm has several goats, a hog, a cow, a large group of chickens and ducks. The farm is about 150 years old and was donated to the city by the Grant family.

The farm has on occasion borrowed other animals from nearby farms to visit the farm, occasionally for
breeding purposes. The livestock pens are off limits to the public, much to the disappointed of many groups. The animals should not be fed anything, as it can be unhealthy for them. Visitors should also keep in mind that the farm has no trash cans, so if you bring it in, bring it out and do not feed it to the goats (even
though they eat anything). The farm does sell fresh eggs and seasonal produce although the quantity is limited and tends to sell quickly.

The farm has a selection of activities for those interested. In the odd apple shed (an original building!) is the farm nature center. On every third Saturday of the month a 'Friend of Deer Hollow Farm' serves as a docent to answer questions for the general public about the center. The center reflects the local diversity of flora and fauna in the park. For the younger patrons, there are hands-on activities, although if an older visitors asks nicely, they might share.

School trips bring in thousands of visitors each year to the farm. Classes are offered for kindergarten aged children up to the fifth grade during the school year. The classes generally involve a tour of the farm, meeting the animals, wilderness exploration of the park and learning about the native American culture of the Ohlone Indians.

The Farm program also offers a summer wilderness camp for kids of first through ninth grades in order for them to better experience the farm and the park as a whole. The program includes a series of hands-on activities with both educational and entertainment goals in mind.
