Russian Ridge Preserve

Overview

Hours

Open a half-hour before sunrise until a half-hour after sunset. The Mindego Hill area will be closed when the National Weather Service declares Red Flag Warning weather.

In summer, the hills of this 3,137-acre preserve turn to gold with the late evening sunlight. Autumn, when the fog recedes, is the ideal time to enjoy the ridge views of San Francisco Bay and the Santa Cruz Mountains through the crisp, clean air. Winter storms occasionally dust the top of the hills with snow.

Diverse plant communities, miles of forest edge, and abundant springs make Russian Ridge an outstanding habitat for wildlife. Large numbers of raptors soar over the lush grasslands, and coyotes patrol the ridges. The steep forested canyons create a secure refuge for a tremendous variety of animals.

History

Russian Ridge was named for Mr. Paskey, a Russian immigrant who grazed cattle and ran a dairy farm here from about 1920 to 1950. Paskey originally leased his land from James "Sunny Jim" Rolph, Jr., then mayor of San Francisco, and later California's governor.

Native Americans are thought to have used the area for gathering seeds, and may have burned some of the grasslands to encourage a bountiful crop the following years.

Borel Hill, is named for Antonio Borel, a Swiss banker who lived here from 1885 to 1910. Borel was involved with the Spring Valley Water Company, which later created Crystal Springs Reservoir.

The district began acquiring the preserve in 1978, through a series of complex transactions, from its owners, who were planning to subdivide and build houses.
