Los Buellis Hills are a short sub−range of hills in the northwestern Diablo Range, in the South Bay region of the San Francisco Bay Area, within Santa Clara County, California.
The hills are located east of the Berryessa community in northeastern San Jose, and slightly west of Felter Road.
The Los Buellis Hills average about 2000feet in elevation.
The hills support a non-native grassland habitat, and are used primarily for cattle grazing. High-voltage transmission lines pass through the hills.
