"Almaden Quicksilver County Park is one of the jewels of the Santa Clara County Park system. In terms of size, historical significance, and natural beauty, it rivals any state park. The park sits on the southern edge of the Silicon Valley, with millions of people and thousands of businesses and industries spreading out below it to the north. It occupies most of the Los Capitancillos Ridge, running southeast from the Guadalupe Landfill to Almaden Reservoir. To the north are the upscale suburbs of the Almaden Valley. To the southeast is the historic mining town of New Almaden. To the southwest is the soaring forested wall of the Sierra Azuls, topped by Mt. Umunhum. The park takes up 4157 acres of steep hillsides, cool forests, open meadows, and deep valleys. It borders two long reservoirs and contains several small ponds. It is crisscrossed by trails, including 34.2 miles for hiking, 23 miles for equestrians, and 10 miles for bicycling." - County Park page
