The city of Monte Sereno, California is named after El Sereno mountain. A portion of the city is built on the foothills of the mountain. El Sereno mountain is paired with El Sombroso mountain on each side of Los Gatos, California. Geology
The San Andreas Fault runs in the valley immediately to the south of the mountain. The Berrocal fault zone runs under the mountain's northern slope. A small, unnamed fault runs in the small valley that leads down to Canon Dr. The northern slope forms the headwaters of San Tomas Aquino Creek. Views
The preserve offers visitors views of Silicon Valley, Los Gatos, California and Lexington Reservoir. The Monterey peninsula can be seen in the distance. Trails
Limited parking is available at the end of Montevina Rd. The Montevina Ridge Trail from there connects to both Bolhman Road and the Aquinas Trail. Aquinas Trail goes from the Montevina Ridge Trail to Sheldon Road, the Serenity Trail and the Loma Vista Trail. The Serenity Trail goes to the base of a power pole overlooking Lexington Reservoir.
