Almaden Valley is the most southwestern area of San Jose. The area received its name after the New Almaden Quicksilver Mines, which were named after the Old Almadén mine in Spain that produced mercury to process ore during the Gold Rush.

Almaden is home to some great primary and secondary schools, such as Almaden Country School and Leland High School.  There are great historical parks like Almaden Quicksilver County Park and outdoor activities, including hiking, biking and fishing at Calero Dam and Reservoir.  The valley is located between the Santa Teresa Hills and the Santa Cruz Mountains.  With Mount Umunhum to the west, it's near the California State Route 85 highway.

The neighborhoods consist of primarily upper-middle class families, with homes owned by local professionals, scientists, professional athletes, and Silicon Valley executives.  Almaden is also home to two top-rated golf courses, the Almaden Golf & Country Club and the Boulder Ridge Golf Club.
