History of Alum Rock Park

Alum Rock Park is California's oldest municipal park, established in 1872 but serving as public land since the pueblo was established in 1777. Located in a valley in the Diablo Range foothills on the east side of San Jose, the 720 acre park offers 13 miles of trails and is rich in natural and cultural history.
